UV-based purification technology promises total bacteria knock-out

摘要

Montreal, P.Q.—An ultraviolet-based air purification system that kills deadly microorganisms at first contact is making its way into biotech cleanrooms. The Sanuvox (www.sanuvox.com) UV Bio-Wall Air Purifier is designed to fit into the center of a cleanroom air duct, integrating five 19-mm high-intensity ultraviolet (UV) quartz lamps attached to five an-odized parabolic reflectors. When properly installed, Sanuvox guarantees a 99.99-percent first-time purification rate. "The Bio-Wall is not a filter, it's strictly a UV purifier, able to destroy the chemicals in the air, or bacteria virus in mold—it's a killer, but it doesn't do anything for dust or dirt," says Aaron Engel, director of marketing. Installation variables include how much fresh air is moving through the duct, the duct size, and air velocity. Offered in 40-, 50- and 60-foot lengths, two units of Bio-Wall are recommended to achieve sufficient UV dwell time when dealing with very large ductwork.
