Cross counter flow
sensible heat exchange
Higher heat efficiency
Complete sealing
Double side pressing plate
Two neighbor aluminum foils form a channel for fresh or exhaust air stream. Heat is transferred when the partial air streams flow crossly and partial air streams flow counter through the channels, and fresh air and exhaust air is totally separated. -
1.Sensible heat recovery
2.Total separation of fresh & exhaust air streams
3.Heat recovery efficiency up to 90%
4.2-side press shaping
5.Single folded edge
6.Completely joint sealing.
