Main feature:

1. Sensible heat recovery

2. Total separation of fresh & exhaust air streams

3. Heat recovery efficiency up to 92%

4. 2-side press shaping

5. Single folded edge

6. Completely joint sealing.

Working principle of  2-side press shaping counter flow heat exchanger :

Two neighbor aluminum foils form a channel for fresh or exhaust air stream. Heat is transferred when the air streams flow counter through the channels, and fresh air and exhaust air is totally separated.
