Steril-Aire's germicidal UVGI emitters eliminate surface biofilm – a mixture of mold, bacteria, viruses, and debris – when installed at the cooling coil and drain pan in an HVAC system. The devices deliver higher output at all temperatures than other types of tubes. Drain pans stay clean and free of debris, eliminating the need to further clean components. A new 61-foot emitter length is available for large indoor AHUs in medium to large commercial and industrial environments.
