AHU use heat recovery ventilator core

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

* Sensible heat recovery

* Total separation of fresh air & exhaust air streams

* Heat recovery efficiency up to 75%

* 2-side press shaping

* Double folded edge

* Completely joint sealing

* Resistance of pressure difference up to 2500Pa

* Under pressure of 700Pa, air leakage less than 0.06%.
