 Product Description
Total heat exchanger is made of ER paper which is featured by high moisture permeability, good air tightness, excellent tear resistance, and aging resistance. The clearance between the fibers is very small, so only the moisture molecules of small diameter can go through, the odor molecules of larger diameter are unable to pass through it. By this means, the temperature and humidity can be recovered smoothly, and prevent the pollutants infiltrating to the fresh air.
 
Top 10 China Total Heat Enthaply Air to Air Crossflow Heat Exchanger
Heat recovery efficiency up to 85%
Enthalpy efficiency up to 76%
Effective air exchange rate over 98%
Selective molecule permeability
Flame retardant and mildew resistance

Working principle
The flat plates and the corrugated plates form channels for fresh or exhaust air stream. When the two air steams
passing through the exchanger crossly with temperature difference, the energy is recovered.
