BioZone Scientific’s CoilCare® - UVGI for Cooling Coil Disinfection

HVAC systems are the perfect breeding ground for growth of bacteria, fungus, and molds because the coil’s function, removing heat from air, also generates condensation in the process. Biological pollutants that are airborne or growing on the moist interiors of HVAC surfaces (e.g., cooling coils, drain pans, or ductwork) over time form a biofilm consisting mainly of mold growth and bacteria. When the HVAC system is operating, a portion of this contamination is introduced into the air stream and spreads through the building, exposing occupants and inhabitants to contamination. The biofilm has another harmful effect in that the heat transfer of the cooling coils is altered, causing the system to loose considerable efficiency and requiring increase energy consumption to perform the same function.

Cooling coils and drain pans exposed to BioZone Scientific’s CoilCare® UV system are cleaned of biofilms, restoring the HVAC system to safe and efficient operation. In addition to the germicidal effect of UV-C light which inactivates microorganisms through ultraviolet germicidal irradiation (UVGI), the airborne gaseous pollutants are broken down by photocatalytic oxidation (PCO), converting them into harmless products. BioZone Scientific’s CoilCare® can provide a return on investment (through energy savings) in 2 years or less. The savings result from reduced coil cleaning maintenance costs and lower energy costs due to improved heat transfer and reduced pressure losses from airflow through the coils.
