The True 3Å Wheel is marketed globally and now competes against numerous other brands that have since adopted aluminum wheels with a 3A molecular sieve desiccant coating. In addition to its low EATR, it also incorporates an anti-corrosion and anti-stick coating to reduce cross contamination. Pre-engineered and factory assembled, the EP Series system also provides the air handling … Pressure Loss (in in. A metric was put in place to report recovered energy divided by the power used to recover that energy. 70. FläktGroup SEMCO wheels provide the solution to the ASHRAE 62 mandate. SEMCO® LLC has introduced the eQ Series, the HVAC industry's most efficient dedicated outdoor air energy recovery system under 15,000-cfm for schools, offices, hotels, and other commercial applications 50,000 square feet and less. It was a concerted effort by SEMCO to understand the real world application of energy wheels. As a result, the outdoor air quantity can be increased from 5 to 20 cfm per person without increasing energy costs. True 3Å Wheel was introduced and patented in 1987. Animal Labs. Cartridges Capable of handling a wide variety of chemical fluids for storage and application. In conjunction with an Energy Recovery Unit the SEMCO wheels help to pre-cool and dehumidify the outdoor air during the cooling season and preheat and humidify the outdoor air during the heating season.
