Heatcraft®’s Heat Recovery fluid coils incorporate many of the features found in Heatcraft®’s Fluid Heating and Cooling coils. They are incorporated in what is commonly referred to as a run-around or loop heat recovery system. Heat Recovery Coils are most often located in an air handling system’s supply and exhaust air stream. They may also be applied in an industrial process’ exhaust stream to recover and reuse the thermal energy.
