Why Ultraviolet Light?

Reduce Energy Consumption

According to the 2008 ASHRAE Handbook, because heat transfer and airflow are restored through the use of UVGI, energy savings can result, with the possibility of payback in less than two years.

Reduce Maintenance & Cleaning

Per Chapter 16, “Ultraviolet Lamp Systems,” of the 2008 ASHRAE Handbook, chemical and mechanical cleaning of air conditioning coils and drain pans can be costly, dangerous, and even difficult. Applying UV light can help maintain system cleanliness by keeping surfaces free of microbial contamination.

Eliminate Mold, Bacteria & Viruses in the HVAC System

UV light appears to be an effective way to lower the risk of infection in the operating room during total joint replacement surgery.

Maintain Peak System Efficiency

As stated by the 2008, ASHRAE Handbook, UV light makes it easy to maintain heat exchange efficiency, design airflow and to improve indoor air quality.

Cut Airborne Biohazards

The Centers for Disease Control recognizes UV as a viable means for the reduction of tuberculosis and in reducing the transmission of other infections in hospitals, military housings and classrooms. Source: CDC, October 1994.

A microbial analysis of 54 air conditioning units at nine schools in California indicated a notable reduction in the levels of microbial growth on the evaporator coils; and total fungal and gram positive bacteria reductions were from 65 to 100% of colony forming units.

UV-C Light

The “germicidal range” of UV light is approximately 200 – 300 nm, with a peak germicidal effectiveness at 254 nm.
