Ultraviolet filtration: Maintaining energy efficiency with UV

Ultraviolet-C energy (UV-C) in HVAC equipment is applied in surface irradiation of cooling coils, drain pans, and other interior surfaces of air handler plenums. This represents over 95% of the UV-C installations in US HVAC equipment. Here, Forrest Fencl, President, UV Resources looks at commercial HVAC UV-C applications, and how the technology can be a cost-effective supplement to air filtration.
