How does it work? 　　The TFA incorporating energy recovery device exchanges the energy from the exhaust air to incoming fresh air. The exhaust air drawn through the exhaust section is passed through half section of the rotary heat exchanger, where it give up its energy to the exchanger. The filtered supply air passes over the other half of the rotating heat exchanger, in the supply section and exchanges the energy. This, pretreated air passes over a cooling (optional) coil, for further cooling, before it is supplied into the area.

Ecofresh advantage over conventional systems Typical recovery: 80% No cross contamination between exhaust and fresh air. Selective adsorption: special grade molecular sieve desiccant allows only water molecules to pass through it, rejecting all other pollutants. Two tier system handling exhaust and supply air stream Inlet damper section Filter section both for exhaust and supply bag filters for dusty application incorporates Ecofresh Heat Wheel along with filtration, damper control, other airtreatment devices/options Supply and exhaust air blower and motor Double skinned, Eco-friendly insulation. Eliminates need for complicated ducting Available in the range from 0.3m/s to 60.m/s Advantage of Ecofresh inside! Total energy recovery, recovers both latent and sensible energy Ecofresh has equal recoveries unlike etched (European) wheels,which are limited in latent recover. For latent recoveries special grade desiccant, Ecosorb-340, ensures selectivity for moisture only; eliminating contaminant carry over through the desiccant almost totally For a given face velocity, recovery nad pressure drops of "Ecofresh" are better than any internationally available rotary heat recovery wheel. A specially, adjustable purge section rules out cross contamination of air stream.(less than 0.04%) A special labyrinth sealing arrangement ensures no cross leakage of air stream between the supply and exhaust section.
