The work environment is decisively affected by indoor-air quality. In many businesses, an air-conditioning centre ensures the proper conditioning (percentage of fresh air, temperature, humidity) of the recirculated airstream.

However, central air-conditioning and ventilation systems also spread spores, bacteria and viruses evenly throughout the building via the circulation, and in some circumstances may promote their increase. Infections and respiratory problems may be the result. UVC disinfection in the central air-duct system effectively prevents this risk, allowing you to meet a major part of the hygiene requirements according to Association of German Engineers (VDI) directive 6022 without the use of chemicals.
