Aluminium crossflow plate heat exchangers (air-to-

Working principle Two neighbor aluminum foils form a channel for fresh or exhaust air stream. Heat is transferred when the air streams flow crossly through the channels, and fresh air and exhaust air is totally separated. Main features 1. Sensible heat recovery 2. Total separation of fresh air & exhaust air streams 3. Heat recovery efficiency up to 80% 4. 2-side press shaping 5. Double folded edge 6. Completely joint sealing. 7. Resistance of pressure difference up to 2500Pa 8. Under pressure of 700Pa, air leakage less than 0.06%
