Engineered Systems - February 2008 - (Page 13) U.V. RESEARCH REPORT EPA RTI New Government Research Studies Indicate American Ultraviolet Leads the Competition in Active “Dosage Per Watt Efficiencies.” June 2006 Report: A June 2006 EPA report compared In-duct UVC fixtures bio-aerosol inactivation efficiency in HVAC applications. Because the amount of UVC energy produced effects inactivation efficiency, all fixtures tested should have had a similar rating/sizing for the number of lamps, wattage and output – this was not the case, and some performance ratings were promoted as higher than others. One manufacturer published a finding that showed their fixture produced a much higher “dose (uWsec/cm2) per watt” rating, however, they simply increased the number of lamps and added reflective material with a rough surface, but only to their product, which unfairly enhanced their results. 48.35% PERCENTAGES REPRESENT THE “DESTRUCTION” OF THE PERSPECTIVE BACTERIA/VIRUS > 99.5% 99.97% 99.96% 98% 99% 99% 93% 96% 99% 47 .09% January 2008 Report: American Ultraviolet chose to re-submit a standard UVC in-duct fixture to the RTI/EPA testing facility, however, this time the fixture had the exact same number of high-output lamps (6) as the Steril-Aire in-duct fixture used in the June 2006 test. Following the same test protocol previously used, the American Ultraviolet fixture is now rated hiigher than all other manufacturer’s fixtures for “dose (uW-sec/cm2) per watt.” In addition, American Ultraviolet’s biological inactivation rates also compared equal to or higher than the others in most instances. Please review the accompanying charts for American Ultraviolet model DC24-6-120 to see how it compares to other manufacturers’ fixtures that also have high ratings.

More than 50,000 of these fixtures are safely operating throughout the world. Designed specifically for HVAC applications, Duct Clean (DC Series) and Coil Clean (CC Series) UVC fixtures increase the value of all air conditioning and air-circulating systems by maximizing system efficiency and prolonging blower life. In addition, American Ultraviolet fixtures treat air that passes through HVAC units with UV light that will reduce, or eliminate, DNA-based airborne contaminants and provide building occupants with healthier air to breathe. All American Ultraviolet UVC fixtures are made in the U.S. and feature: • Highest Output Lamps (800mA) • “Green” lamps (≤ 8mg of mercury) • Two-year (17,000 hours) guarantee on lamps • Easiest to install and replace patent-pending lamps Contact American Ultraviolet today. We’ll clear the air about the EPA report. And, in addition to clearing the air in your building, we’ll help you ensure HVAC system efficiency, prolong equipment life and lower your energy and maintenance costs. CC Series CC Series fixtures feature a moisture-proof design and easily mount in various configurations for pass-by air decontamination and/or to irradiate cooling coils and drain pans.
