In-duct UVGI systems are equipped inside heating, ventilation, and air-conditioning (HVAC) systems to treat coils and inactivate airborne pathogens as they flow through ductwork.
Surface Disinfection in Commercial Air Systems
Treating HVAC coils with UVGI keeps the coils, drain pans, and wet surfaces of your systems clear of microbial growth, which can significantly reduce energy efficiency. Such devices emit relatively low levels of UV energy that is continuously delivered 24 hours a day, making them a practical application.
Air Disinfection in Commercial Air Systems
UVGI systems designed for air disinfection apply a more intense level of UV energy to inactivate airborne pathogens as they move through your HVAC duct. While HVAC air disinfection systems usually require more power and more lamps (or both) to inactivate pathogens within a short period of time effectively. These types of systems are generally placed downstream of your HVAC coils to keep the coil, drain pan, and wetted surfaces free of microbial growth while simultaneously disinfecting moving air.
While UVGI for air disinfection can be used inside any HVAC system to disinfect airborne infectious pathogens, coil treatment UVGI is not powerful enough for disinfecting air and should not be relied upon for treatment beyond surfaces. Treating your coils can reduce HVAC maintenance and improve operational efficiency in large commercial systems.
