An "Air to Air" Heat Exchanger will reduce the energy costs of any commercial clothes dryer by at least 40%.

All dryers need a constant supply of hot air (about 70ºC) to dry the load.

You pay constantly to heat this air.

The colder the initial air supply, the more you pay for energy to heat that air.

The Heat Exchanger is connected to the exhaust air duct of the clothes dryer, and transfers waste heat from the damp exhaust air, to fresh air which is introduced directly into the back of the dryer, (after is has been preheated by the heat recovered from the exhaust air stream).

1. Staff subjected to constant draft of air (summer and winter) feeding clothes dryer.
   
2. Massive energy waste.
   Hot damp air exhausted directly to outside

1. Room ventilation is independent of the dryer air supply.
   
2. Energy is recovered.
   Heat is transferred from the hot, damp exhaust air stream to the fresh supply air stream.

 
This heat transfer process can heat fresh air from 0oC to over 50oC, thus reducing the dryer's demand on its heat (energy) source.  (Gas, Electricity or Steam).

Moisture in the exhaust air stream is 100% separated from the fresh air at all times.   Nothing but heat is transferred from the exhaust air, to the fresh air flowing into the dryer cabinet.

For most dryers with a heat exchanger, energy costs are reduced by 50%, but the brand of dryer, the type of laundry, and the geographical location will cause variations. We guarantee a saving of at least 40%. The colder the fresh air normally consumed by the dryer, the better the performance of the heat exchanger.
