Duct Mounted UVGI System

Environmental conditions within an air-duct promotes the growth of biological contaminants (viz. mould). This contamination eventually spreads down the ductwork and into the living spaces. The in-duct UVGI System is designed to maximize airborne kill of dangerous pathogens such as viruses, bacteria, and mold spores and other pathogens.

This duct mounted UVGI system is designed for intensive airstream UVC irradiation. The system features multiple UV high-output germicidal UV lamps which sterilize airborne biological contaminates as they pass by. The In-duct UVGI system is fully customizable and can be configured to fit a wide variety installation parameter. The desired exposure time for adequate dosage in ductwork is an important design criterion. When there is limited time of exposure due to the velocity of the moving airstream, more than one UV light unit may be required to achieve adequate exposure time.

The primary variables important to the design configuration of a UVGI system include air duct dimensions (W x H x L); airflow rate; UVC lamp specifications (viz. UV power, arc length, lamp radius); lamp quantity and locations; duct reflectivity; and filtration.

The average irradiance for a typical air duct application should range from 1,000 to 10,000 μW/cm2 depending on the microbes to be inactivated and operating conditions such as air temperature, air velocity, and humidity.
