Thermal wheel & efficiency

A Thermal Wheel, also known as a Rotary heat exchanger, or Rotary air-to-air enthalpy wheel, or Heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, in order to recover the heat energy. Other variants include Enthalpy wheels and Desiccant wheels. A cooling-specific thermal wheel is sometimes referred to as a Kyoto wheel.

The answer is Yes. I have used them down to 1000 cfm. Surprisingly very efficient. Just research the various applications be cause there are many types out there.
