AIR DISINFECTION – ULTRAVIOLET GERMICIDAL IRRADIATION (UVGI)

Ultraviolet germicidal irradiation (UVGI) uses short-wave ultraviolet

(UVC) energy to inactivate viral, bacterial, and fungal organisms so

they are unable to replicate and potentially cause disease. In short,

UVGI does not kill viruses, it just deactivates them.

• UVGI system is a cost-effective and a flexible solution.

• Can be placed within ducts, Air Handling Units (AHU), plenum spaces, or in rooms above occupied areas.

• Low electrical consumption if installed centrally within a unit-- approximately 2-3 kw for a 100k sf office building.

• Ideal conditions are, 200-400 fpm air velocity & 80-95F ambient air dry bulb temperature.
