UVR-KL

Viruses, bacteria, mold, spores, fungi, etc., can rapidly multiply in damp, dark HVAC systems and spread throughout the building via air conditioning systems, making the indoor environment infectious. Our UV germicidal devices installed in air ducts inactivate pathogenic microorganisms “on the fly.” Building managers should consider installing this technology in their buildings.

Principle of operation

Our family of UV air disinfection racks, or our UV frame series, has been designed with UV tubes of various power ratings (48, 72, 95, and 155 W) and frame lengths (400, 650, 880, 1200, and 1550 mm). We use three types of technical designs for flexible adaptation to HVAC duct systems:
– UV rack mounted outside the air duct – integrated, meaning with controls built into the junction box (cut to fit the duct wall). See the image!
– UV rack mounted outside the air duct – not integrated into the junction box, i.e., with external controls (duct wall cut to size).
– Indoor UV rack – not integrated into the junction box, i.e., with external control.
For the most effective germicidal and bactericidal effect, an air velocity of 2–2.5 m/s in the air duct is recommended.

To destroy microorganisms, a radiation dose of 10–100 Ws/m² is generally required, although the radiation sensitivity of individual organisms varies greatly. The D10 dose value can range from 7 Ws/m² (Escherichia coli) to 1000 Ws/m² (fungi). The D10 value is the UV radiation dose that reduces an initial number of germs by 90%. The effect of UVC radiation on coronaviruses is well known. The D10 dose for these viruses is approximately 40 Ws/m2.
