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 … w.g.) 2 What are molecular sieves and why is the 3A version the right choice for total energy wheels? All our technical and sales documents in one place. FläktGroup SEMCO wheels provide the solution to the ASHRAE 62 mandate. True 3Å  is available singly, in self-contained conditioning units, or as retrofits of existing wheels. A metric was put in place to report recovered energy divided by the power used to recover that energy. >> Read the site inspection summary "Longevity of the SEMCO TRUE 3A wheel: Confirmed in Continuous Laboratory Exhaust Environment", Competitor Wheel                                       SEMCO True 3Å. SEMCO recovery wheels employ fluted aluminum media for true laminar flow and require minimal maintenance. True 3Å Wheel was introduced and patented in 1987. No SEMCO wheel has ever failed an AHRI certification test. Comparison of SEMCO's EXCLU-SIEVE wheel perfor-mance with published data by competitors. We specialize in the design and manufacture of a wide range of air climate and air movement solutions. Semco offers four basic cap seals for cartridges: Threaded-Cap Seal, S-Seal, Tri-Seal Cap and T-Seal. Designed specifically to replace a wide range of existing heat wheels and energy recovery wheels, many that have performed poorly, or failed completely. As a result, the outdoor air quantity can be increased from 5 to 20 cfm per person without increasing energy costs. Minimal maintenance has been completed since the systems are only shutdown during extended holidays or on an emergency basis. (See also Wheel.) It was a concerted effort by SEMCO to understand the real world application of energy wheels. Hygienic Hygroscopic wheel with molecular desiccant coating, which avoids contaminant carryover. “It is said that imitation is the sincerest form of flattery,” says John C. Fischer, SEMCO’s director of technology and the patented True 3Å Wheel’s inventor. SEMCO developed a wheel providing end users the industry best RER. 70. SEMCO LLC is celebrating the 30-year anniversary of its True 3-angstrom (3Å) Total Energy (TE) Wheel used in commercial, institutional, and industrial facility HVAC systems. 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. Note 1: Results Based upon laboratory testing showing average contaminant carry-over for eight different chemical families. SEMCO’s True 3Å Wheel The SEMCO True 3Å Wheel has the industry’s highest recovery performance (AHRI Certified) and Recovery Efficiency Ratios (RER).

In addition to its low EATR, it also incorporates an anti-corrosion and anti-stick coating to reduce cross contamination. ASHRAE 84 procedures followed, contaminant familes chosen by the Georgia Tech Research Institute. Why 3A? SEMCO pioneered an application of a 3 angstrom desiccant on wheels to improve indoor air quality in buildings by not transferring exhausted VOCs back into the fresh outdoor air. Cassette – The framework supporting the wheel. – Technology Consultant, SEMCO Inc. Johns Hopkins Ross Research Building: The Owner’s Perspective. [NEW] Energy Recovery Wheel Purge - ASHRAE 62.1 Compliance. The wheel has a molecular sieve-desiccant coating that is selective in what it absorbs from an exhaust air stream.

With more people at home this spring, SEMCO has experienced an increase in line hits caused by people digging before calling MISS DIG. It is available as both a single (EP) or dual (EPD) wheel system. AHRI Guideline V was developed to calculate the efficiency of energy recovery ventilation. SEMCO's EP Series offers the ultimate performance in the transfer of total energy (both latent and sensible). SEMCO sound attenuating and fire rated panels are quickly assembled together to provide enclosures for equipment and processes. Bearing failure of SEMCO’s heat wheel caused seals to rub media, closing off air flow.
