UV-FCU-CL is composed of:

UV-FCU-CL works by direct irradiation, with its application we obtain a strong reduction of the microbes present both on the exposed surfaces and in the passing air, such as: Bacillus, Coli, Clostridium, Legionella, Vibrio, Salmonella, Pseu-domonas, Staphylococcus, Streptococcus, Virus, mould. This allows the sanitization of the air and the radiant batteries in the FANS (FANCOIL) and the U.T.A. Inserted in the section between the fan and the radiant thermal battery UV-FCU-CL disinfects the heat exchange fins receptacle of dirt and microbes radiating them directly and eliminates all bacteria and viruses from the air. The ignition of the appliances can be managed by means of special control units (MASTER series), which can manage various operations:
  • Programmed switching on. It is possible to program the time of irradiation by means of an adjustable timer.
  • Automatic switch-off. A safety system switches off the lamps in case of entry of personnel.
  • Fault alarm. In case of failure of one or more lamps, a light on the panel will be activated.
  • Hour counter. Management of the replacement of lamps about to run out of life.
  • Automatic switch-off. A safety system switches off the lamps when personnel enter.
  • Fault alarm. A warning light is switched on in the event of a fault.
  • Hour counter. Control of the replacement of lamps about to run out of life.


The UV-FCU-CL air disinfection system can be applied for air disinfection in fancoils and air handling units. (U.T.A).
For installation on FANCOIL it is sufficient to fix the supplied clips in the space between the fan and the heating/cooling battery; the lamp is inserted between the above sections and locked with the clips. Installation is simple and it is also possible to use it on already installed and working fan coils (re-trofit technology on already existing systems). The supplied electronic power supply unit, which is small in size, is supplied with a plug/socket connection system that simplifies lamp replacement.
For the sanitization of the air and the radiant batteries in the air treatment units (A.T.U.) the UV-FCU-CL device directly radiates, with UV-C rays, air filters and cooling and/or humidification batteries inside the A.T.U., to avoid the formation and growth of microorganisms potentially harmful to people’s health. The use of the UV-FCU-CL represents an economical and reliable solution to stop the access of microbes to social rooms or to controlled contamination chambers, through a simple installation that is safe for the personnel, since everything is limited to an irradiation inside the AHU ducts, allowing a considerable saving in management costs and health protection from infectious diseases such as:
1) Sick Building Syndrome;
2) Legionnaires’ disease (Legionella Pneumophila - typhus of legionnaires); 
3). Tuberculosis (Mycobacterium Tub.)
4) Monday or humidifier fever.

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.
