Ultraviolet Lighting Improves Coil Efficiency, Indoor Air Quality

November 2010

Airborne pollutants, such as mold, bacteria, dust and pollen, are a serious issue for facilities in that they can hinder airflow, negatively effect the efficiency of heating and cooling systems, and irritate allergies and other respiratory ailments. However, these pollutants are no longer plaguing the IRS facility in Covington, Ky. facility, thanks to the installation of ultraviolet lights on its cooling coils.

Airborne pollutants, such as mold, bacteria, dust and pollen, are a serious issue for facilities in that they can hinder airflow, negatively effect the efficiency of heating and cooling systems, and irritate allergies and other respiratory ailments. However, these pollutants are no longer plaguing the IRS facility in Covington, Ky. facility, thanks to the installation of ultraviolet lights on its cooling coils.

"These lamps have been so effective that plans have been made to consider adding fourteen more Steril-Aire ultraviolet lighting systems to the facility," says Dan Tarkington, president of Four Seasons Environmental, Inc. "This installation will provide U.V. lighting for all 23 cooling coils in the facility."

Furthermore, the IRS facility in Covington, Ky. isn’t the only local facility looking to ultraviolet coil lighting. Plans are underway to add ultraviolet lighting to two air handlers at the NIOSH Taft Laboratory in Cincinnati. The $6,000 pilot project will be used to determine if further ultraviolet coil lighting at the NIOSH facility is advisable, pending funding.

In all, the ultraviolet coil lights can offer the following benefits: energy savings, maintenance savings, improved indoor quality, water conservation, extended food shelf life (when used in food-storage facilities), and LEED contribution for facilities seeking LEED certification..
