UV-FLOW .... CL is composed of:

The UV-FLOW .... CL must be anchored to the ceiling to generate a special horizontal flow that will create a "zone of intense radiation" below the ceiling, which destroys all airborne microorganisms, due to natural convection of air.
The air, rich in microbes, is continuously treated and disinfected by the ultraviolet rays; a progressive decontamination of bacteria, viruses and molds is made, decreasing the possibility of bacterial, viral transmissions and contaminations in general.
Continuous operation ensures a permanent progressive healthy environment, especially in hospitals, schools, restaurants, indoor workplaces as offices, laboratories, etc..An extremely important disinfection activity  can be done in hospitals intensive cares units, to prevent the spread of diseases such as TB and other transmissible pathologies through air.


The UV-FLOW .... CL is a controlled multidirectional flow device, with four powerful UV lamps inside and a narrow emission peak at wavelength of 235.7 nm. (nanometers), which has a strong germicidal effect against all micro-organisms (molds, bacteria and viruses).
There is also a parabolic, mirror bright aluminum surface, which generates UV rays parallel beams by reflection. These beams pass through a special black laminated grid that directs UV rays to form a unidirectional flow ("blade UV"). When installed according to the instructions, this device can be used in the presence of people for intensive and continuous air disinfection.



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 light genuinely works if properly applied and with the necessary precautions. The difference between a quality project, and an application that fails to bring the desired results, lies in the degree of knowledge about the subject, and level of experience acquired over time. Light Progress has been developing successful projects worldwide since 1987, and has built a client portfolio consisting of important companies in all fields requiring certified hygienic conditions to produce quality products and services.
