UV-SMELL-SQ is composed of:

UV-SMELL-SQ can be installed directly inside the hood, providing a plenum (ducts enlargement) or directly inside the centralized apiration and filtration system.
The air flow must pass entirely through its “grid” of UV-C lamps placed on its Stainless Steel AISI 304 body.
Apart from the device, the Supply Box contains ballasts, a lamps’ LED Synoptic view, a digital hourcounter and the alarm check.
The module is designed to house also the TiOx® filter, a special Light Progress filter coated with nano-structured titanium dioxide and silver salts (optional) that, in combination with the very high UVC power emitted by lamps, is an excellent photo-catalyst that degrades pollutants and organic and inorganic compounds (SOV, NOx and VOC volatile organic compounds, nitrogen oxides).
TiOx® filter performs further oxidation of polluting particles, and contributes significantly to the deodorizing action of UV-C.
The special materials used for UVSMELL-SQ ensures watertight (IP 55) protection, high temperatures (45/50 °C) resistance.


In restaurants or industrial/ community kitchens, during food cooking phases, fats, pollutants and unpleasant smells are generated; this may be disputed by authorities and give often rise of legal issues with the neighborhood.
Applied inside kitchen hoods and aspiration systems, UVSMELL-SQ contributes significantly to minimize these problems;
fats are carbon and hydrogen compounds, with a structure made of complex chains. If fats are exposed to an intense UV-C irradiation, they absorb part of this powerful energy, and molecules, placed in a higher energy state, become more reactive. For this reason they recombine with oxygen present in the air.
This process causes a particular and immediate chemical reaction, the “cold combustion”. Results of this reaction are organic and odorless short chain gases, such as carbon dioxide (CO2), water, etc.., normally present in air.
So the air filtered by UVSMELL- SQ during normal cooking, reduces the formation and deposits of fat and the consequent risk of fires, limiting also the growth of molds that feed usually on fats.
UV-SMELL-SQ reduces the need of aspiration system cleaning and maintenance, extend filters’ life but, more importantly, offers the possibility to work safely.
UV-SMELL-SQ uses UV-C lamps and/or UV-C+O3 (Ozone) lamps, and it is the firts device in the market that can handle ozone or ozone-free lamps, alternatively or even combined together, according to clients’ needs.
In these kind of applications, UV power is often enough to reach great results, but ozone, persisting in air for few seconds before turning in simple oxygen, maximizes UV-C performances.




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.
