confirms the ability of the SEMCO 3A wheel to limit the transfer of gaseous contaminants below the .045% claimed in our literature. SEMCO’s True 3Å Wheel The SEMCO True 3Å Wheel has the industry’s highest recovery performance (AHRI Certified) and Recovery Efficiency Ratios (RER). Coaxial Cartridge Two sections of the cartridge and both have their own molded pistons. Importance of the 3A Molecular Sieve Desiccant Coated Total Energy Wheel to the HVAC Indoor Air Quality (IAQ) Market (Revision 3) Background on the development of the 3A molecular sieve “total energy” recovery wheel: During the energy crisis of the 1970’s, the … ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality, defines the minimum outdoor air ventilation rates required to achieve acceptable indoor air quality. 6500 850. This wheel is supported by an improved extruded aluminum structural hub, spokes and rim system. Johns Hopkins Ross Research Building: • 450,000 cfm of combined laboratory/vivarium • 164 fume hoods, 154 biosafety cabinets and general exhaust through recovery wheels • Eight SEMCO 3Å molecular sieve coated total energy 66. Comparison of SEMCO's EXCLU-SIEVE wheel perfor-mance with published data by competitors. All rights reserved. SEMCO Antimicrobial Activity Wheel Research. This wheel is supported by an improved extruded aluminum structural hub, spokes and rim system. SEMCO recovery wheels employ fluted aluminum media for true laminar flow and require minimal maintenance. 8000 757. 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. • This wheel is supported by an improved … Bearing failure of SEMCO’s heat wheel caused seals to rub media, closing off air flow. Today, 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. SEMCO 3A heat recovery wheels recover heat from exhaust streams that contain contaminants that must not be reintroduced into labs or other industrial applications. 81. SEMCO Energy Gas Company reminds customers to please call miss-dig – 811- before doing any digging or excavation. According to the company, its combination of a proprietary 3A molecular sieve desiccant coating on a durable fluted aluminum wheel revolutionized sensible and … GTRI Cross Contamination Testing Report. It has the industry's lowest contaminant carry-over and has been installed to process air such as those exhausted from many medical research centers and laboratories-- facilities where solutions to … SEMCO's EP Series offers the ultimate performance in the transfer of total energy (both latent and sensible). Designed specifically to replace a wide range of existing heat wheels and energy recovery wheels, many that have performed poorly, or failed completely. One such product with ultra-low EATR’s is Semco’s model #TC3 ‘True 3A’ Energy recovery wheel. It is available as both a single (EP) or dual (EPD) wheel system. Our collective experience is unrivalled. “It is said that imitation is the sincerest form of flattery,” said John C. Fischer, SEMCO’s Director of Technology and the patented True 3Å Wheel’s inventor. The focus of SEMCO wheel technology is to have nearly equal latent and temperature transfer. Longevity of the FläktGroup® SEMCOTM TRUE 3Å wheel: confirmed in continuous laboratory exhaust environment Find out how FläktGroup SEMCO wheels have played a prominent role in the laboratory HVAC systems in Johns Hopkins labs and how the technology … 84 procedures followed, contaminant familes chosen by the Georgia Tech Research Institute physical.
