DescriptionSemco EPHC Series Packaged Energy Recovery Systems.The FläktGroup SEMCO EP packaged energy recovery system offers the ultimate performance in the transfer of total energy (both latent and sensible). Pre-engineered and factory assembled, the EP system also provides the air handling capability for the building’s exhaust and supply air. The system can be selected to precondition outdoor air going to other conventional air handling systems or as an integrated system that provides total space conditioning with the additional heating and cooling options available.The heart of this system is a technologically advanced True 3Å desiccant wheel. In addition to providing superior performance, the wheel’s 3Å molecular sieve-desiccant coating is selective in what it adsorbs from an exhaust airstream. The desiccant rejects airborne contaminants while it transfers water vapor, thus providing total energy transfer from the exhaust to the supply airstream. Selectivity allows True 3Å to be used in critical applications, including recovery from contaminated airstreams. In the past, energy recovery was avoided or limited to sensible-only energy exchange in applications like these.The True 3Å wheel uses a fluted media with an aluminum substrate, which is coated with a fast-acting, adsorbent desiccant surface. As the transfer media slowly rotates between the outdoor and exhaust airstreams, the warmer air surrenders its sensible energy to the aluminum. This energy is then shifted to the cooler airstream during the second half of the revolution.Just as the temperature is captured and released, so is the moisture. The True 3Å molecular sieve-desiccant coating has an enormous internal surface area and strong attraction to water vapor. Since the opposing airstreams have different temperatures and moisture contents, the vapor pressure will also be different. This pressure difference is the driving force in the transferring of latent energy.By using the desiccant coating, the True 3Å wheel recovers the moisture from the exhaust airstream to the supply airstream without the airborne pollutants exchanging. This very important and unique feature has been well documented through independent laboratory and field testing. (A copy of the Georgia Tech Research Institute study is available free of charge.)
