IAQ Looks at Technology in New Ways
ORLANDO, Fla. - Exhibitors of IAQ products at the 2010 AHR Expo have not been idle. They have been improving on existing technologies for increased accuracy and performance, and in some cases, flipping concepts in order get better results. A sampling of new products is provided in this short and snappy roundup.
Dexen Industries (www.dexen.com) showed its IAQ monitor system, which measures oxygen levels rather than carbon monoxide. According to the company, an enclosed area is compromised when oxygen levels decrease at a faster rate than the rate of CO. The system recognizes an unsafe level of CO (less than 18.3 percent) and shuts down fossil fuel-burning appliances. It also triggers increased fresh air from the ventilation system.
The GeneralAire (www.generalaire.com) TERSus provides three technologies in one air purification system. The first stage is an electrostatically enhanced needled media filter that removes up to 96.3 percent of microscopic particles and airborne allergens as small as 0.3 microns. The second stage features 254 nanometer wavelengths of UVC light amplified to 10,000 times the intensity of sunlight to kill viruses and bacteria too small to be filtered out by high-efficiency filter media. In the third stage, UV light combines to create a chemical reaction with a permanent TIO2 Anatase semi-conductor called photocatalytic oxidation (PCO), converting VOCs into harmless carbon and water.
Panasonic Home & Environment Co. (www.panasonic.com) announced the expansion of its WhisperGreen® premium ventilation fan product line with four new models. Designed for 4-inch ducts, the new 80-cfm models (FV-08VKM2 and FV-08VKS2) are quieter than their predecessors at <0.3 sone. For larger bathrooms with 6-inch ducts, the new 130-cfm models (FV-13VKM2 and FV-13VKS2) offer low sone levels of 0.5. The FV-08VKM2 and FV-13VKM2 feature the SmartAction® motion sensor. All models are Energy Star® rated, HVI certified, and ideal for complying with ASHRAE Standard 62.2.
