AIR PURIFIERS: we guarantee healthy and clean Air since more than 30 years - Light Progress
Air disinfection in community structures (schools, hospitals, offices) is very important, this avoids the diffusion of viruses and microbes that are often the cause of more or less serious infections.
The application of UV-C devices improves the living conditions of the occupants of the spaces, disinfecting the air and keeping the components of the air conditioning system clean and efficient, without the use of chemicals and keeping under control the consumption of energy and water. 
The keys to continued HVAC performance are the cleaning of cooling coils, drainage trays and other "wet" components.
Thinking of a situation without UV-C products all the components defined as "wet", with time and poor cleaning, are coated with biofilm and organic compounds. These products, resulting from poor cleaning, spread through the air ducts inside the building.
When mould, biofilm and other organic compounds accumulate:
-The air inside the ducts deteriorates in terms of quality. Odours develop and respiratory irritants, pathogens and allergens spread.
- The flow of air through the batteries becomes limited due to fouling, which leads to a reduction in comfort and energy performance. 
- Equipment and material life is reduced and maintenance requirements are increased.
All these elements threaten the "three E's" of a building: Energy, Efficiency and Economy... the common factor for the realization of a green building.
Ultraviolet (UV-C) lighting is a technology that responds to maintaining the cleanliness of HVAC components, reducing the use of chemicals by controlling energy and water consumption.
UV-C helps maintain or retrofit IAQ significantly. The application of UV prevents formation and reduces the spread of different categories of organisms, which can grow and/or spread in modern air treatment systems. These include pathogens (viruses, bacteria and fungi, which can cause a variety of diseases), allergens (bacteria and molds, which can cause allergic rhinitis, asthma, humidifier fever and hypersensitivity pneumonia), and toxins (endotoxins and mycotoxins, which can cause a variety of toxic effects, irritation and odors).
According to ASHRAE and the U.S. General Services Administration, UV-C rays prevent microbial "growth and transfer" in living spaces.

F.A.Q.

Ultraviolet rays are electromagnetic waves which are part of light. Electromagnetic waves are divided into three main wavelength bands, expressed in nanometers, nm: Ultraviolet rays (UV) 100-400 nm Visible rays (light) 400-700 nm Infrared rays (IR) 700-800,000 nm UV rays are in turn identified in three bands:

  • UV-A (315-400 nm) with tanning properties;
  • UV-B (280-315 nm) con proprietà terapeutiche e di sintesi della vitamina "D";
  • UV-C (100-280 nm) with germicidal properties.

UV-C rays (100-280 nm) have a strong germicidal effect and reach their maximum efficacy at the 265 nm wavelength. The germicidal effect of UV-C radiation covers bacteria, viruses, spores, fungi, moulds and mites; this is mainly due to the destructive effect of the UV-C rays on their DNA, which damage their reproductive system and prevent them from replicating.

Bacteria, Viruses, Spores, Fungi, Mould, and Mites are all sensitive to, and can therefore be eliminated with, UV-C light. Mircrobes cannot acquire resistance to UV-C light, unlike that which occurs using chemical disinfectants and antibiotics. UV rays are ecological. Polluting the environment is inevitable using normal disinfectants. Directly inhaling the vapours, or swallowing food products contaminated by any contact with said chemical disinfectants, can also give rise to a number of serious risks. In cases where chemical disinfectants cannot be eliminated (food, pharmaceutical, healthcare industries, etc.), using ultraviolet rays for disinfection allows a reduction in their use, with considerable economic savings and greater care for the environment, while maintaining and almost always improving the level of disinfection. UV-C light devices can be installed in environments and on machinery and be programmed to maintain the same level of disinfection day and night, guaranteeing ideal hygiene conditions, without highs and lows. On the contrary, chemical disinfectants are effective only during their actual use. Using LIGHT PROGRESS equipped luminaires, operating costs are negligible; it could be said that “LIGHT PROGRESS” UV-C systems do not require maintenance except for the normal replacement of the lamps. The cost/benefit ratio is considered excellent; the devices are both powerful and long-lasting. Hence the elimination of germs using UV-C technology is low-cost and highly effective compared to (or in combination with) other systems.

UV-C really does work when applied correctly and with the necessary precautions. The difference between a quality project and an unsuccessful application is in-depth knowledge and experience gained over time. Since 1987, Light Progress has been carrying out successful projects all over the world and has acquired a clientele of major companies in all sectors that require verified hygienic conditions to produce quality products and services.
