AIR DISINFECTION – GERMICIDAL ULTRAVIOLET (GUV)

Germicidal Ultraviolet (GUV) uses short-wave ultraviolet energy (UV-C) in the 200 to 280 nm wavelengths to inactivate viruses, and to kill bacteria and fungal organisms so they are unable to replicate and potentially cause disease. Technically , GUV does not kill viruses it just deactivates them. • GUV is most effective in wavelengths of 265-270 nm and effectiveness drops off the further the UV is from this value. The optimum value varies depending on the type of germ. • GUV system is a cost effective and a flexible solution. • Can be placed or in rooms above occupied areas, within ducts and in Air Handling Units (AHU). Can also be used by robots in non- occupied spaces. • Low electrical consumption. Not included in lighting energy budgets.
