Viruses, bacteria, mold, spores, fungus, etc. can grow rapidly inside the damp and dark HVAC systems and get distributed all over the buildings through the air-conditioning systems, making your indoor environment infectious. Our in duct installed air disinfection devices inactivate the pathogenic microorganisms “on the fly”. Facility managers should strongly consider incorporating this technology into their buildings.

Functional principle

The UVB air disinfection Stick was designed as one-tube and two-tubes family with different electrical power (36, 60 and 95 W) and with different lengths (195, 395 and 500mm). With this system we can adapt flexibly to the local conditions. In order to achieve the most favourable germicidal, bactericidal effect, an air speed of 2-2.5 m/s is required in the UV lamp area.

Installing two-tubes Sticks in an air duct:


A radiation dose of 10 to 100 Ws/m2 is generally required to kill microorganisms, while different organisms have very different radiation sensitivities, which can range from 7 Ws/m2 (Escherichia coli) to 1.000 Ws/m2 (fungi). The effect of UVC radiation on corona viruses is known. The D10 dose is around 40 Ws/m2. The D10 value is the UV dose that reduces a certain initial number of germs by 90%.
