UV-STICK-AX-SCR is composed of:

The device works by direct irradiation of UV-C rays. When the lampis turned on, it reduces the microbial load in the air and on the surfaces enlightened by the UV lamp. For example, in 2÷3 seconds, at a distance of 10 cm from the device, you will achieve a 99% reduction of the bacteria Bacillus, Coli, Clostridium, Legionella, Vibrio, Salmonella, Pseudomonas, Staphylococcus, Streptococcus, etc. The use of this device is allowed only in absence of personnel inside the AHU environment. In case of opening of a sector of the AHU, the switching-off of  the lamps must be provided, to avoid personnel’s affections at eyes (conjunctivitis) and skin (rash). The programming of the switching-on of the device can be made using specially designed electronic control units (MASTER series), which, above all in case of installation of various equipment, can manage various operations such as:

  • Timing. It is possible to program the duration of irradiation using of a timer.
  • Turning-off. A safety system switches off the lamps when people enter inside the AHU duct.
  • Failure alarm. In case of failure of one or more lamps, it will trigger a warning light on the framework clean contact.
  • Hour Counter. To control the duration of a lamp and substitute it at the end of its lifetime.


UV-STICK...AX-SCR device includes a series of UV-C reglette of reduced size and different lengths, to irradiate thermal batteries (coils) and internal filter sections of AHU - Air Handling Unit – in central air conditioning systems; their purpose is to eliminate the microbial load.
The device is a reglette built entirely in extruded anodized aluminum, IP55 protection and fitted with a reflecting screen in mirror bright aluminum, to increase the power of radiation, through the reflection of UV-C proportion that would otherwise be wasted in the opposite direction to the useful ones.
The extruded aluminum case, contains special electronic ballasts to maximize yield and duration of UV-C lamp.
To avoid flying splinters of glass after the collapse of the UV lamp, a protection of the UV lamp by means of the special thermo-retracted sheath UVLON®-PIPE (Tetrafluoroethylene), with UV-C transparency >85%. can be provided, always as an option UVLON®-PIPE is a patented system to withstand the wear and tear; it has low adhesion to any product or substance, is resistant to any aggressive chemical at high or low temperatures.  It is a polymer conforms to F.D.A. tests for use with foodstuffs.
The constituent materials of UV-STICK...AX allow its use even in harsh operating conditions (high humidity, low temperatures, etc..), or where conditions require a high resistance to chemicals and weathering.
We suggest to install one or more UV-STICK…AX-SCR in a layout that allow the device/s to irradiate coil’s surface entirely, to obtain an homogenous treatment of inner surfaces.
For this reason Light Progress offers a special and adjustable mounting kit to install devices properly.
Mounting kit is made in anodized aluminum, it can be used to install devices in serie, attacching them directly to AHU’s wall.
Devices are connected through SCR serial connectors, it is possible to switch them all ON through only one power supply cable
UV-STICK-SCR is built with high quality, extremely resistant components, it works perfectly in difficult operative conditions (high Humidity, low temperatures, etc).

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.
