UV Lamp For AHU (Air Handling Unit)

A UV-C lamp integrated inside an Air Handling Unit (AHU) is an advanced solution for maintaining clean and hygienic indoor air in centralized HVAC systems. As warm outside air enters the AHU, it may carry contaminants such as mold spores, bacteria, viruses, and volatile organic compounds (VOCs). The air first passes through filtration, where larger dust mites particles are captured.

UV-C lamps are installed inside the AHU chamber between the filter and cooling coil directly exposing the cooling coil to germicidal ultraviolet light. These lamps continuously disinfect both the moving air and the internal components. The UV system helps prevent biofilm formation on the cooling coils, reduces microbial buildup, and minimizes the circulation of harmful pathogens throughout the building, and by integrating UV-C technology into existing AHU or HVAC systems it enhances indoor air quality, improves system efficiency, and reduces energy consumption and maintenance requirements, making it an ideal solution for hospitals, commercial buildings, pharmaceutical facilities, schools, and other high-occupancy environments.

Also installing the lamp downstream of the coil (on the leaving-air side) allows continuous surface irradiation and helps prevent microbial buildup before air is distributed through the duct system.
