INDUSTRIAL ELECTRICAL INSTALLATIONS: HOW TO DESIGN AND IMPLEMENT THEM SAFELY

Carrying out an industrial electrical installation is more complex than a civil electrical installation.

 This is due both to the presence of more complex machinery and to the strict regulations on the subject. For this reason, it must be designed and carried out by experienced and qualified personnel.


FM distribution systems

Downstream of the secondary distribution panels is the actual energy distribution network which is designed to serve all motive power, lighting, service sockets and all the equipment that services user systems.

 This distribution follows the architectural development of our customers' facilities and is essentially conveyed through steel ducts and walkways designed to contain and mechanically protect the distribution lines; it then continues in the detail of the last few metres with steel piping until it reaches the final user.

 Electricity distribution is carried out according to the specific needs of each customer, always considering basic design criteria.

Switchboards

Process control, electro-instrumental or on-board machine control panels


Process control and electro-instrumental interface boards are boards which generally do not involve significant electrical power. They are mainly used to contain the hardware of the control systems, PLCs or DCSs which, with their signal acquisition and measurement peripherals, interface with field instrumentation for the measurement and processing of information on the production process or are used to regulate, even remotely, machine parameters, operating temperatures andswitching lights and air conditioning machines on or off in order to save energy. 


In addition to acquisition peripherals, these switchboards also house the interfaces for the field instrumentation, which in the chemical-pharmaceutical sector often represent the EEx (safety) barriers for the field where there is hazardous area equipment.


In these switchboards, there is generally also an electro-pneumatic system where the control valve system is combined with pneumatic drives called solenoid valves. In these sections, there are pneumatic circuits powered and distributed through compressed air-driven devices.


Telesicurezza Service issues the accompanying technical documentation for each supply: single-line and functional wiring diagrams, front and internal topography, terminal boards, equipment list, test certificates and conformity documentation in accordance with current regulations.

  • A short journey to discover various types of automatic gates and maintenance rules.

    The use of automatic gates and doors has become commonplace and their use gives you the convenience of not having to get out of your car to open or close them.

    But what is the best type of automation? How should installation be carried out? Is there any particular obligation to maintain the gate?

    We will try to answer these main questions in this article.

    The EN 12445 deals with the testing methods to be applied to automatic gates in order to verify compliance with the requirements of EN 12453.

  • Installation of automatic gates: who can do it, compliance and permits

    European safety standards prohibit the DIY installation of an automatic gate by a private individual. Once the work has been completed, the installer must issue a certificate of conformity, known as a declaration of conformity, and a user and maintenance manual for the gate, which lists all the components installed.

    It is also compulsory to install safety devices, such as photocells, on the automatic gate to comply with the requirements of EN 12453 standard. Once the gate has been installed, the qualified technician (a certified electrician) must carry out calibration correctly.

    The installation of an automatic gate does not require any DIA (Denuncia di Inizio Attività in edilizia) or SCIA (Segnalazione Certificata di Inizio Attività) permits, but as mentioned above, the work must only be carried out by certified and authorised technicians and installers.

    Obviously, if the automatic gate is to be installed on public land, or in particular areas with planning restrictions, you will need to apply for authorisations and permits.

    Once the work has been completed, you must have the CE declaration of conformity label affixed to the gate, indicating the identification number of the automatic gate and the date of installation.

  • The safety regulations for an automatic gate

    Since 1 August 2002, the reference for the safety of automatic gates has been the European standards EN 12453 and EN 12445, which replaced the Italian standard UNI 8612. These two standards refer to "Industrial, commercial and garage doors and gates - Safety in use of motorised doors".

    The first, EN 12453, deals with the safety requirements for the installation of an automatic gate, barrier or motorised door to prevent possible dangers to people in industrial, commercial and residential environments (including condominiums).  For example, this standard details the maximum level of anti-crushing safety to correctly calibrate the opening and closing force of your gate.

Automatic gate and sectional door maintenance

An automatic gate can break and cause greater problems than a traditional gate, although current gates have a long operating life. It may be that the automatic gate does not close properly due to misalignment or incorrect calibration or you may have electric motor or arm problems. An automatic gate that is locked open or locked in the middle of the path are both also foreeseeable problems.

These problems can be avoided with proper maintenance.


Maintenance of the automatic gate is good to do even before the winter. If temperatures drop excessively, the automatic gate can fail to open in cold weather. In all these cases, Telesicurezza Service is available to have the gate serviced or repaired by our gate automation technicians.

Automatic door maintenance

An automated appliance can break and cause greater problems than a normal access door, although automatic doors have an operating life of around 1,000,000 openings. It may be that the automatic door does not close properly due to misalignment or forcing just as it can happen that the automated door stops halfway through the path. These problems can be avoided with proper maintenance performed by specialist technicians.


In all these instances, Telesicurezza Service is available to have your automation serviced or repaired by our experts.

Telesicurezza Service is able to supply and install any automation on windows or doors or to supply the entire window frame including any masonry work necessary for the automated opening system.

Automatic doors

From shopping centres to public places and private homes: where automatic doors can be installed.


This type of closure is ideal in contexts with a high intensity of transit (such as shops, shopping centres, restaurants, hospitals, railway stations, public buildings, etc.) as it allows the flow of people to be controlled and promotes thermal insulation, reducing heat loss in winter and promoting coolness in summer. In commercial establishments, automatic doors are also fitted with anti-panic emergency opening systems that make it possible to manually unlock the door in the event of a fault, power failure or the need to quickly evacuate the environment for safety reasons.


It is also specifically required in places where it is necessary to eliminate architectural barriers and maintain high levels of hygiene, such as hospital wards and operating theatres. In these environments, automatic doors are also fitted with hermetic and semi-hermetic closures because it is important to ensure high levels of thermal, acoustic and sanitary insulation.

  • How an automatic door works

    There is no need to push or pull, as these special doors do not require any physical effort to open. Automatic doors open and close every time their photocell, the device that detects a presence in the vicinity, detects the presence of a person, allowing them to pass through even with their hands full.

    Very beautiful and the result of an innovative technology, they are often used in luxury environments and are able, thanks to their visual impact, to change the perception that people have of a structure, increasing its prestige.

    Let's take a closer look at all the advantages of installing these doors!

Types of automatic doors

Automatic doors are mainly of 3 different types:


Automatic sliding doors

Whether single or double paned, they can be configured in a wide range of variants. They are safe and easy to use and install, they adapt to any entrance and allow simple opening/closing and secure hermetic closure.


Automatic revolving doors

Available with two, three or four sectors, they are ideal when temperature control is of primary concern. They regulate inlet/outlet flows very well, thus ensuring an optimal separation between the internal and external environment.


Automatic swing doors

These automatic doors can be installed on both new installations and existing doors, they can be operated manually and their main feature is to ensure maximum use of the passageway. 


As already mentioned, sliding doors are available in a wide range of models and are made of different materials and designs. They offer numerous advantages in terms of functionality and comfort and can be installed in any structural context, even during renovation and on plasterboard walls.

  • Safety

    Automatic entrances are certified in compliance with safety standards and offer ease of use and maximum convenience. They are equipped with easily identifiable stop and emergency devices that can also be operated manually and are connected to photocells capable of sending stop commands if they detect anybody within the door's sliding path.

  • Practicality

    The automatic doors reduce the overall dimensions and are extremely silent in their movements. They can be installed in most structures (even as escape routes) responding well to any architectural request without having to resort to complicated masonry works, such as modifying the flooring. Even with a quick and easy installation process they guarantee performance and reliability.

  • Savings

    Automatic doors are space-saving and extremely quiet in their movements. They can be installed in most structures (even as escape routes) and can meet any architectural requirement without the need for complicated masonry work, such as changing the floor. Even with a quick and easy installation process, they guarantee performance and reliability.

    They are suitable for all places with a high frequency of traffic and are the ideal solution when space is limited.

  • Aesthetics

    Sliding doors bring prestige to the entrances of the facilities where they are installed, offering attractive design solutions and simple, elegant styles. They also adapt to any design requirement and are perfect for installation in:

    Businesses, public and private offices, hotels, bars, restaurants, shops, shopping centres, hospitals, etc.

    Banks.

Sectional doors

Beautiful and well made!


Aprico automatic sectional overhead doors (https://www.aprico.com) installed and sold by Telesicurezza Service are the smartest solution for garages because they improve the aesthetics of the building and offer excellent thermal insulation of the interior. Elegance, comfort, energy saving, mechanical anti-intrusion mechanisms, quality details and finishes are the elements that make Aprico sectional overhead doors the best alternative to traditional and simple overhead sheet metal doors.


New looks, increasingly high quality materials and finishes for garage doors.


And to make access, transit and manoeuvring easier, there are clever and safe opening mechanisms.


Now that anonymous (and sad) garage door closures have been banned for good, doors with an increasingly attractive look are appearing on the street thanks to the elegant contemporary lines and the noble materials of the door panels - mainly wood, available in an infinite range of colours and finishes - new generation doors now perfectly match the other doors and windows of the house, helping to define their style and character. But the surprises go far beyond style. What makes garage owners (and would-be garage owners) even happier is the development of locking system technology: traditional up-and-over doors are giving way to more practical, convenient and secure sectional overhead doors, the intelligent and space-saving alternative.

  • Sectional doors: there's no catch!

    Why is the sectional mechanism more intelligent? Because it eliminates the main defect of up-and-over doors, which swing, tilt and overflow outwards when opening and closing, requiring more caution on the part of the operator, taking up more space inside and outside the garage and requiring more complicated manoeuvres by car. Sectional overhead doors, on the other hand, open vertically and slide upwards on guides that run parallel to the wall, and at the end of their stroke they position themselves parallel to the ceiling.

    Maintenance in general, as well as being a legal obligation, must be aimed at ensuring the continuity of essential public services (hospitals, means of transport, banks, ministries, etc.), avoiding irreparable damage to priceless assets in terms of culture and history as well as economic damage from lost production.

    Among the laws and standards (UNI and CEI) dealing with maintenance, we would like to mention the standard CEI EN 60964, Classification CEI 17-21 "Common recommendations for high voltage switchgear and control equipment", which contains important guidelines concerning maintenance, based on a correct cooperation relationship with the manufacturers of the various equipment. In art. 10.3 the standard warns that the effectiveness of maintenance depends essentially on the way in which instructions are prepared by the manufacturer and then implemented by the user.

    The article provides recommendations for both the manufacturer and the user.

    To the manufacturer it recommends the issue of a maintenance manual and specifies what information it should contain, and to the user who wishes to carry out maintenance himself, to ensure that his personnel have sufficient qualification and detailed knowledge of the specific switchgear and control equipment.

    The standard also recommends that the user records a range of information about the equipment, the dates and degree of maintenance work carried out, the service history, periodic records of operations carried out, and other indications (e.g. short circuit operations), references to any failure reports. In the case of failures and defects, it recommends that a report be made and that the manufacturer be informed, specifying the particular circumstances and the measures taken.

In general, the voltage supply from the distributor is the only source of electricity that can support regular operation of an operation, whether it is productive or public, excluding emergency supplies which generally are not able to ensure the regular operation of the whole system. The user's electrical system originates at the delivery point which represents the boundary between the distributor's system and the user's system and from that point the user is responsible. Laws and regulations require electrical systems to be kept efficient with an acceptable level of safety; to fulfil this obligation it is necessary to carry out constant, periodic, scrupulous and adequate preventive and improvement maintenance.


It is appropriate to highlight the need to periodically carry out maintenance of the whole system, with the disconnection of the delivery point, in agreement with the distributor, in order to allow for the maintenance of all the equipment (including that of the distributor) and piping (copper rod or cable lines and relative terminations) connecting it to the user. The total disconnection of the entire system allows the user to operate in complete safety and carry out a complete maintenance operation.

Telesicurezza Service is able to supply different types of transformer substations:


  • Open cabin with electrical equipment located in masonry cells with front metal mesh;
  • Cabins consisting of medium voltage switchboards with transformers in masonry cells or in metal enclosures;
  • Cabins with prefabricated masonry structure;
  • Cabins with prefabricated metal structure.

Energy saving

'Energy saving' refers to all activities, measures and technologies aimed at reducing and optimising energy consumption. Energy saving and energy efficiency are essential to reduce the environmental and climate impact of fossil fuels. Consumers who are sensitive to this issue can make use of various solutions, contributing to environmental sustainability and, at the same time, reducing their bills: the effective reduction of electricity and gas consumption through good habits, the transition to the free energy market with the choice of a new operator or the use of technologies that allow the rationalisation of the energy used and self-production with the least possible waste.

  • Solar panels

    Solar panel technology makes it possible to reduce the take from the grid and lower the cost of energy. With photovoltaic systems consisting of solar panels, it is possible to capture sunlight and convert solar energy into electrical energy, producing electricity and heat. It is a 'clean' form of energy as it does not use or release harmful substances into the environment.

    The photovoltaic module is made of fibreglass, a tough cover that protects it from shocks, including atmospheric events such as hail, and consists of interconnected photovoltaic cells resting on a plastic element at the back that gives the module rigidity. The anodised aluminium frame provides high resistance to corrosion.

    The energy of photovoltaic systems can be stored in batteries that make it always available (so-called "stand-alone" or "isolated" systems) in areas not served by the grid, or it can be used immediately, even without batteries (this is the case of "grid-connected photovoltaic systems") to reduce one's energy bill.

  • What is included in energy saving

    When it comes to saving energy at home, this category includes the installation of:

    photovoltaic systems

    solar thermal panels for water heating

    energy-saving light bulbs and LED bulbs

    For example, the use of energy-saving lamps can reduce lighting costs by up to 60%.

    Energy savings can also be achieved by thermal insulation of houses through energy efficiency upgrades in buildings as well as boiler maintenance. All of the above measures fall under the definition of energy saving and allow a reduction in energy consumption for the same services. This is why we talk about energy efficiency, i.e. the ability to use the energy provided in the best possible way. Each technology or efficiency operation has a generic estimated percentage of savings, which however varies depending on the individual case.


    Facile.it's free consultancy service helps you to find the best solution for improving the energy efficiency of your home or place of business, cutting costs and choosing energy sources that do not impact the environment.

  • Domestic hot water and house heating directly from the sun

    The sun is an inexhaustible source of energy, which can be collected, stored and used for many purposes. A solar thermal system allows the sun to be used for heating homes and water.

    This type of system can be installed in place of a traditional boiler which uses fossil fuels such as petroleum derivatives, or in combination with a newly developed boiler, perhaps a pellet or condensing boiler, to improve efficiency and save money.

  • Solar Collectors: Same principle, different technologies

    The sun heats the earth's surface with its rays, and it is on this simple concept that solar thermal energy is based. Thanks to the principle of radiation, solar energy can be collected and stored.

    What many people don't know, however, is that different types of solar thermal panels have been developed, which have different yields and are adapted to different climatic regions of the earth.

    There are the classic glazed solar panels, which are also the first to be developed and installed, and vacuum tube panels, which have a better yield and are also suitable for colder climates, such as ours in the winter months.

    In turn, there are two variants of solar thermal systems, namely Natural Circulation, which is cheaper and more compact, and Forced Circulation, which has a better yield and a higher installation cost.

  • Energy saving: Eco-bonuses and deductions

    For several years now, energy efficiency and redevelopment work has also been eligible for specific tax breaks known as Ecobonus.

    The benefits for energy saving provide for a variable IRPEF deduction depending on the type of energy requalification work that one decides to carry out. For example, the Ecobonus for energy saving includes operations to improve thermal insulation, the installation of solar thermal systems or heat pumps.

Ground systems and protection of atmospheric discharges

What is an atmospheric discharge protection system?


An atmospheric discharge protection system is designed and installed according to precise regulations whose purpose is to reduce the probability of lightning strikes to a structure. In order to know how likely a facility is to be considered self-protected (i.e. it does not require an atmospheric discharge protection system), a detailed study by a qualified technician according to certain European technical regulations is required. This report is a compulsory document to be carried out by all employers for their operation.


If the technical report reveals the need for an atmospheric discharge protection system, it must be designed and installed by professionals registered with technical orders and registers.


Atmospheric discharge protection systems include rod-type systems, such as the typical lightning rod, rope-type systems and cage-type systems.


Therefore, if an activity has an atmospheric discharge protection system, it must be periodically checked by an inspection body or by ASL and ARPA.


This system must then be checked by an inspection body periodically to check its condition and that all maintenance has been carried out regularly. This check is required by Presidential Decree 462.

    Surge arresters (also known as SPDs - Surge Protection Devices) are mechanisms for safeguarding equipment from overvoltages and are characterised by two important advantages: they are inexpensive and can also be incorporated into an existing installation.

    A surge arrester is like a container connected between L-PE and which has an infinite impedance (Z) that does not change the installation's operation.

    When an overvoltage occurs, this causes the impedance at the ends of the container to drop, allowing the current to be absorbed. The drainage of the overvoltage keeps the voltage at the ends of the container constant, and the equipment will not be damaged if the voltage is compatible with the immunity and insulation level of the equipment.

  • The importance of proper installation

    The topic cannot be considered closed without devoting a few words to the subject of installation techniques; very often considered less important, they play a fundamental role in equipment protection.

    The consequence of incorrect installation may even be to render the surge arrester completely useless, and it is for this reason that it is important to verify that the equipment to be protected is connected to the equipotential bonding bar, and not just any bar, to which the SPD is connected.

    In addition to correct installation, it must be stressed that it is essential to use products that comply with the standards in force, which are considered the official method for creating legally compliant and therefore safe systems.

Home automation

What is home automation

Home automation includes all those processes that deal with the study of technologies to improve the quality of life in homes and buildings. But it does not stop there, as home automation can increase the performance and functionality of the various systems that make up a home.


This is done by optimising consumption and providing access to various functions such as security, energy saving, control, communication and comfort.


While a traditional system can be controlled by activating normal commands, such as a switch, which are incapable of communicating with each other, the home automation system allows the various functions to be governed from a single control point, guaranteeing coordinated management of the various smart devices in the home.

Networks and structured cabling

Structured cabling networks - LANs


The need to connect and interconnect more and more computer devices through the Internet or with dedicated LANs, makes it necessary to create data networks with high speed, reliability, flexibility and scalability.

 In buildings, whether civil or industrial, cabling that respects this is not just an interconnection system but a strategic element, sharing the resources of the company, employees and customers and projecting the factory computer system as the fulcrum of the company itself.

 In a data transmission system, the nerve centre is the structured cabling

system made up of a set of copper or fibre optic cables, active and passive equipment (bridges, routers, switches) that are suitably wired and interconnected to allow connectivity between the various components of the company network represented by the end users (computers, smartphones, tablets, etc.).

 The heart of the structured cabling system is the star centre, represented by a rack cabinet in which all the signal management devices (bridges, routers, switches, etc...) and connection to the external data and telephone network (HDSL modem, switchboard) are grouped. The electrical connection to the sockets intended for the end users is developed from the star cabinet.

 The network architecture must be suitable for providing adequate transmission support for communications within the company premises, in compliance with the reference standards. The cabling must be realised in full compliance with the standards and regulations in order to obtain a high degree of reliability, security and functionality, as well as to allow a high level of diagnostic support.

  • Climate control systems: new regulations in force

    On 1 June 2014, new regulations came into force on air conditioning, both winter and summer, including air conditioners, boilers and other devices used for the comfort of buildings. 

    Both new and existing air conditioners must be accompanied by a system booklet - consisting of various sheets - in compliance with the one approved by the Ministry of Economic Development and launched in implementation of the rules contained in Presidential Decree 74/2013 on maintenance. In the case of previously installed air conditioners, this is the responsibility of the owner or user of the property, who must hire a technician to fill in the relevant data. The old booklets should not be removed but attached to the new one. They can be filled in manually or electronically.

    As well as establishing that a new booklet is needed to accompany the systems, the new standard also requires action to be taken on the forms of the air conditioner energy efficiency control reports (both during ordinary maintenance and checks and when assessing energy efficiency).

    In particular, energy efficiency control interventions must be carried out according to the periodicity established by Presidential Decree 74/2013, which envisages verification every two or four years, depending on the type of system adopted. The obligation to carry out periodic checks is the responsibility of the owner of the building or the tenant, who bears the risk of any administrative sanction in the event of non-compliance with the obligation. Telesicurezza Service is always able to carry out periodic checks, not only to avoid penalties, but above all to keep its systems efficient with consequent savings in electricity.

System with radiators or heaters

Now present in most homes, the traditional heating system is far from extinct as it remains a suitable and "convenient" solution in many situations.

  • Continue

    In addition, today there are various types of heaters that can become pieces of furniture, easy to manage and convenient to have in the home, especially if associated with certain precautions that simplify maintenance and maximise performance.


    As with the underfloor heating system, the traditional heating system uses water as the heat carrier fluid, in this case based on heat transmission by convection, but does so at higher operating temperatures (at least 70°). Only in this way can the radiators release heat into the room.


    At the heart of this operation is a boiler which heats water and transmits it to the radiators.


    Boilers can be of various types, depending on the heat output, fuel, exchange technology, type of air draught, etc. Today there are boilers that can also be used for heating water. Today there are boilers that also allow considerable energy savings, while also keeping the environment cleaner, such as condensing boilers.

Baseboard heating

The skirting board heating system is an innovative system of constant and homogeneous heat propagation for heating any type of room.

    This evolution of radiant systems makes it possible to heat every corner by improving heat distribution, with the great advantage of significantly reducing energy costs and increasing climatic comfort because it works with very low volumes of water (the water model uses 1/5 of the amount needed for a radiator) and, thanks to the uniformity of the heat, it allows the thermostat to be set at lower values. Savings will be even more evident if connected to renewable and sustainable energy technologies, such as photovoltaic systems and solar thermal panels, which heat water while consuming less in the short term.


    Very similarly to traditional systems, radiant skirting board heating works through the flanking of two pipes inserted in the lower part of the walls and hidden by the skirting board, one containing hot water inlet and the other cold water outlet.

Baseboard heating: water and electric variants

The water version can be operated with any heat generator (gas or oil boiler, heat pumps, etc.) but also with renewable sources, whose heat is released from the skirting board heating to the walls. 

  • Continue

    This system reduces the emission of thermal energy, and therefore costs, while increasing efficiency.


    There is also the option of choosing the electric variant to the water radiant system, in this case using the electric resistance to produce heat. In all cases the masonry work for installation is minimal, does not involve demolition of walls and is therefore perfect for conservational restoration, even of historic buildings.

Wall heating system

A variant of the underfloor system is wall heating. As with skirting board heating, it is based on the same principle of propagating heat by radiating it onto the wall and releasing it to the room.

  • Continue

    The heating elements inside the radiant panels installed on the walls of the house are heated with electrical energy or by coils in which water flows, which, as soon as the desired temperature is reached, transmit heat by radiation.

    Compared to underfloor heating, wall heating is easier to install as the radiant panels are simply covered with plaster which, in addition to convenience, allows for faster heat distribution.

    As with all radiant heating systems, this type offers better air health: less dust and humidity.

Floor systems

Underfloor heating


This type of heating system can be either closed-circuit water heating, i.e. consisting of pipes, or electric heating, i.e. consisting of electrical resistance. 

  • Continue

    In both cases, the system emits heat by radiation from the bottom upwards, spreading it evenly throughout the room concerned.

    In this way some of the limits of a traditional system are overcome: the dispersion of heat upwards and the high operating temperature to keep the areas away from the radiator warm; the continuous movement of dust in the air; the size of the radiators on the walls!

    An underfloor system, also called "radiant panel", raises the average surface temperature and consequently with the same operating, comfort temperature, the air temperature can be kept lower.

    The underfloor system is more efficient than convection systems and leads to a minimum saving of 10% for the same heated building.

    Standard regulating "radiant" systems: UNI EN 1264.

District heating system

A district heating system is a district heating system that uses a series of pipelines in a network and transports heat from a power station to individual units.

  • Continue

    Compared to traditional systems, district heating is an excellent choice in terms of energy consumption (lower) and environmental impact (lower).

    It all starts with a district heating plant that produces heat and distributes it to end users through a network of pipes.

    This system undoubtedly has advantages in terms of safety, since the central plant will be subjected to frequent and strict testing; from an economic point of view, since the cheapest fuels on the market at the time will be used; in terms of maintenance, which is very limited since the supply takes place remotely in another plant; without forgetting the reduced environmental impact given the production of the same quantity of heat with optimised use of fuel.

Heating system with natural gas or LPG boiler

Speaking of costs:benefit ratios, it is very important to consider the type of power supply when choosing a heating system.

  • Continue

    Certainly in Italy, due to the widespread diffusion of the methane gas network, this is the gas most used by users, both private and public; while LPG is an excellent alternative in areas not served by the methane distribution network, using the installation of an LPG tank that can be rented or purchased, or used on a free loan basis.

    The yield in terms of calorific value is very similar between the two gases, and in both cases we talk about clean gases because compared to other fuels they do not pollute much.

    But let's look at some specific characteristics of each one below.

    For users connected to the methane network, methane arrives at the installation in a gaseous state, passing through a meter that measures consumption. The advantages include: low initial investment and price, practicality, limited space requirements and low-pollution combustion.

    It is also available in areas easily reached by the methane network, as it is transported in a liquid state. The advantages of LPG include: low initial investment thanks to the possibility of loaning the tank for use, practicality, the possibility of arriving anywhere, higher fuel prices than methane, and clean combustion.

Convector heating

Usually used as a supplement to other heating systems to speed up the spread of heat or to increase its intensity in very cold environments, convectors certainly play a major role in the speed and uniformity of heat diffusion.

  • Continue

    This type of heating is based on the principle of convection, which is nothing more than an exchange process: heat rises while cold air falls and is sucked in by the device.


    Thermoregulation and heat accounting

    By means of thermostatic valves installed on individual elements, each building unit can regulate the temperature independently.

    Some systems have a meter that is able to allocate consumption for each individual building unit.

    As of June 2017, heat metering is compulsory for all central heating systems throughout Italy (Legislative Decree no. 102/2012 and subsequent amendments and additions).

Water systems

Water-sanitary systems: supply and drainage networks

Telesicurezza Service operates in the civil and industrial sectors with competence and professionalism, guaranteeing continuous technological innovation of its materials. The company, which is constantly expanding, offers a wide range of services and solutions.


Turning on the tap in your own home and having access to drinking water, including hot water if necessary, is possible thanks to an essential system for modern homes: the water-sanitary system.


Water systems allow a constant supply of drinking water, so it is essential to pay due attention to the quality of water intended for human consumption, considering that it can be altered by external agents such as chemical and microbiological factors.

Preserving good water quality must be the main objective of those designing, installing, operating and maintaining water distribution networks. Some simple preventive measures can be the selection of pipe materials, correct sizing of the system (actual calculation of actual pressure losses) and maintaining hot water temperatures above 50°C.

Water systems

A sanitary water system includes

 - an adduction or supply system, consisting of all the networks, components and equipment that allow the adduction and distribution of hot and cold water to the various users of a building;

 - a drainage system, which allows the disposal of the quantities necessary to meet the needs of the users.

Adduction networks

A water supply system starts at the point of connection to the public drinking water supply and ends at the point where the water is used, i.e. the sanitary appliance (tap, bath, bidet, etc.).

The supply systems in almost all homes are connected directly to the public water supply network.

  • Continue

    Within the network, the water is kept at a pressure of approximately 5 to 6 bar, so that it can reach the highest floors of the buildings, while in the water distribution pipes in the buildings the pressure must not exceed 3 bar to avoid noise, water hammer and pipe breakages. To that end, pressure reducers are used to maintain the set pressure downstream of the system. These reducers are installed upstream of the internal distribution network and downstream of the meter.

Tanks and autoclave systems

When the pressure is not sufficient to reach the highest floors of a building, auxiliary lifting systems must be installed, such as the autoclave - a hermetically sealed metal tank containing a compressor that pumps air into the tank to prevent pressure variations and allow the system to operate at full capacity.

  • Continue

    For correct operation, the autoclave is combined with an electric booster pump whose task is to push the water up to the top floor of the building,

     using a one-piece polyethylene underground tank for containing not particularly aggressive liquids, built using the rotational moulding technique with constant wall thickness (7/10 mm).

Pipes and special components for water networks

The distribution network generally consists of horizontal distribution pipes, vertical risers, distribution pipes to the floors and to the various appliances, and shut-off devices (valves).

  • Continue

     The materials used in water networks are generally galvanised steel, copper and plastics (non-toxic polyethylene for drinking water and polypropylene). For example, galvanised steel is used to prevent corrosion by oxidation and for its excellent resistance to the stresses induced by pressurised water. Plastics, which are more widely used in recent years, are often chosen for their advantages in terms of reduced assembly times and for their greater lightness and manageability (they weigh about 10 times less than steel).

     

     However, all netting must be insulated to prevent heat loss.

Water meters and counters

Drinking water distributed by water systems, although complying with the specific values set by law, may nevertheless contain a number of substances (e.g. encrusting salts) that can cause serious damage both to distribution networks and to the appliances that use the water. It is therefore possible to treat the water before it is distributed in order to reduce the presence of undesirable substances.

  • Continue

    Water treatment equipment includes water purification filters, which retain sand and suspended solids in the water; polyphosphate dispensers, which introduce stabilising salts into the water to inhibit the precipitation of encrusting salts and/or form protective films against corrosion; and softeners, which transform encrusting salts into soluble salts through the action of ion exchange resins.

Regulations

As with other types of systems, the installation of the water system is governed by very precise regulations that make it compulsory to comply with certain construction standards, whether for a completely new home or one undergoing renovation. 

  • Continue

    The reference regulations are those contained in Ministerial Decree 37/2008 of the Ministry of Economic Development, on the subject of "installation activities of systems inside buildings" (it replaced Law 46/90). It is also important to remember that, on completion of the work, the person in charge of the company that modified or installed the system must issue the client with a declaration of conformity.

Air treatment plants

Air Handling Units

The air handling unit, better known by its acronym U.T.A. (air handling unit), is equipment for treating air in closed environments. It is usually made up of a heat exchange coil with chilled water (so evaporation takes place in the evaporator of the refrigerating machine) and hot water, both for cooling and heating, or a direct expansion coil in which the refrigerant gas circulates, for which evaporation takes place in the coil itself inside the rooms where it is used, an air filter and a low head intake/outlet fan.


For large air-conditioning systems, the definition of central air handling units, or A.T.C., is adopted. (air handling centres), whether they are all external air or mixed air. Their purpose is to take the air and treat it according to thermo-hygrometric requirements. The parameters involved in air treatment are temperature, humidity, velocity and purity. For each of these parameters there is a component of the machine capable of controlling, regulating and/or modifying it.

  • Video inspection of Air Treatment Plants: what is the operating procedure

    Good and correct maintenance of the aeraulic systems also includes a video inspection of the air treatment systems.

    Visual inspection is a preliminary operation to the cleaning and sanitising phase of the air treatment systems, necessary for complete evaluation of the state in which they are found and therefore plan subsequent maintenance procedures.

    Given the importance of this phase in the air duct management process, we have decided to produce an article in which we will deal with the subject of visual inspection in a complete and in-depth manner, analysing every aspect and explaining the most correct procedure for carrying it out.

  • How an air treatment system or VMC is made

    The UNI 10339:1995 standard defines an air treatment plant or aeraulic plant as "The set of equipment, devices, accessories and controls necessary to achieve the desired air quality under the predefined conditions".

    This definition would therefore include air conditioning/climate control, thermoventilation and controlled mechanical ventilation (CMV) systems.

    In other words, all those devices that allow the achievement of a certain air quality in closed environments according to certain parameters of temperature, humidity, air movement and purity.

    These are therefore systems that not only ensure air exchange and filtration, but also cooling, heating and dehumidification, and are therefore very complex and made up of several components, such as:

    Air handling units (AHUs);

    Air ducts;

    Diffusers, vents and grilles (or room air terminals);

    Ventilation valves;

    Flow rate controllers;

    Control dampers;

    Silencers.

    Each system can be designed differently. It is therefore necessary to be familiar with the structure of a system and its components before cleaning. Visual inspection can be very useful in this respect.

  • What is the purpose of visual inspection of industrial air handling systems

    Included in those ordinary maintenance operations of the air ducts, aimed above all at cleaning and sanitising, the visual inspection of the aeraulic systems represents a fundamental step because it allows to check in detail

    Plant characteristics;

    Operating status of the system;

    Presence of dirt (dust, insects, mould, rust, etc.) in the ducts;

    Healthiness of the critical points of the air ducting systems;

    Conservation status of the filters.

    As we know, correct management and maintenance of air treatment systems is fundamental not only for the perfect efficiency of the systems themselves, but also for better indoor air quality.

    The air treatment units and ducts of an aeraulic system, in fact, are subject over time to the accumulation of pollutants, micro-organisms and dirt.

    These substances, if not removed, can be dispersed into the environment causing serious damage to the health of the individuals occupying a building.

  • Visual inspection of aeraulic systems: what to check?

    The main purpose of the visual inspection is therefore to provide a sort of snapshot of the current state of an aeraulic system from the point of view of both hygiene and maintenance, in order to assess and plan targeted cleaning and sanitising operations.

    The system components to be inspected with greater attention are above all:

    Air handling unit (AHU) and all its related components and accessories (air intake dampers, filters, recovery tank, drainage siphon, walls, heat exchange coils, humidifiers etc...);

    Air supply ducts and terminals;

    Cooling towers.

    For each of these parts of the plant, the presence of dirt, sediment, mould, obvious traces of biofilm and any other possible cause of microbiological contamination and/or clogging must be carefully assessed.

    According to the agreement between the State and the Regions on the evaluation and management of the hygiene of air treatment systems, the recommended frequency of visual inspections is annual.

    More frequent checks may be necessary in the event of changes in environmental or working conditions, the temporary presence of sources of pollution or wear and tear.

  • Air treatment systems operating procedure: how is the video inspection carried out?

    Internal video inspection of air ducts is carried out by inserting a wire-guided device inside the air-carrying ducts, equipped with a high-definition colour camera and LED lighting, capable of returning clear and detailed images of the system being inspected.

    The visual inspection takes in the whole plant, from the external air intake to the internal grilles. The robotic device is able to inspect both circular and rectangular ducts in:

    - Vertical;

    - Horizontal;

    - Slope.

    This provides an accurate picture of the health and internal situation of the ducts.

    The entire procedure will then be documented with images and videos that will make it possible to identify the points and conditions of fouling of the system, in order to assess whether it complies with the current regulatory framework, or whether remediation or maintenance work is required.

    At the end of the video inspection, the data collected is entered into risk assessment sheets, in accordance with the provisions of the Consolidated Safety Act (Legislative Decree 81/2008).

  • Legislation

    Legislation on air treatment in the workplace

    - Legislative Decree 81/2008 (implementing Article 1 of Law no. 123 of 3 August 2007) - "Consolidation Act on the protection of health and safety in the workplace";

    - Accordo Stato-Regioni "Procedura operativa per la valutazione e gestione dei rischi correlati all'igiene degli impianti di trattamento aria" - 7 February 2013;

    - Standard UNI 10339:1995 - "Aeraulic systems for wellness purposes. Generalities, classification and requirements. Rules for the request for proposal, offer, order and supply".


  • Technical inspection of air ducts: when is it needed?

    In the above-mentioned State-Regions Agreement, it is stated that for the "persistence over time of the proper functioning of the systems and for the maintenance of the hygienic requirements it is necessary to carry out periodic cleaning and maintenance operations that must include a visual inspection and, if necessary, a technical inspection".

    The technical inspection is essential when the visual inspection detects traces of microbiological and chemical contamination inside the air ducts.

    This procedure involves sampling and technical checks on all the components of an aeraulic system in order to:

    Diagnose criticalities;

    Evaluate the corrective measures to be taken;

    Define the timeframe for action.

    The technical inspection monitors all the components of the system, starting from the external air intake, following the air flow to the interior, including the inspection of the AHU and all the components of the ventilation system, assessing in particular

    Efficiency of filters and coils, pressure difference upstream and downstream of the filtering equipment and maintenance of airflow;

    The level of microbial contamination and/or the presence of pathogens hazardous to health;

    The amount of airborne particulate matter dispersed from the system into the indoor environment and deposited in the ducts.

    At the end of the procedure, the technicians in charge of the maintenance of the air extraction and air treatment systems, having evaluated the results, will indicate any necessary maintenance, cleaning and sanitisation.
