The FläktGroup® SEMCOTM True 3Å Wheel has the industry’s highest recovery performance (AHRI Certified) and Recovery Efficiency Ratios (RER). Anti-corrosion, anti-microbial, anti-stick face coatings are standard. This wheel is supported by an improved, extruded aluminum structural hub, spokes, and rim system. The True 3Å Wheel is available as a standalone wheel, in self-contained conditioning units, or as a replacement for existing wheels.
AHRI Guideline V was developed to calculate the efficiency of energy recovery ventilation. A metric was put in place to report recovered energy divided by the power used to recover that energy. FläktGroup SEMCO developed a wheel providing end-users the industry’s best RER.
FläktGroup SEMCO pioneered an application of a 3 Ångstrom desiccant on wheels to improve indoor air quality in buildings by not transferring exhausted volatile organic compounds (VOCs) back into the fresh outdoor air. Contaminant carry-over with True 3Å is less than .045%. It was a concerted effort by FläktGroup SEMCO to understand the real-world application of energy wheels. The focus of wheel technology is to have nearly equal latent and temperature transfer. Having an enthalpy wheel results in not only significant cooling season energy savings but, equally important, the ability to operate at much lower winter ambient conditions without condensation or frost formation.
FläktGroup SEMCO energy recovery wheels employ fluted aluminum media for true laminar flow and require minimal maintenance. They effectively operate with low-efficiency filters without impacting the long-term performance of the recovery device.
