Air-To-Air Heat Exchangers
Key Features
- Filterless, low maintenance
- User friedly
- Compact design
Product Description
häwa air-to-air heat exchangers with a highly conductive aluminum core grid system have two separate closed air circuits, each of them equipped with one fan and sealed per IP 54. This assures that outside air does not penetrate into the interior of the cabinet.
The fan of the internal circuit draws hot air from the cabinet and blows it down along the heat exchanger, where it is cooled via the cooling fins and forced back into the interior of the cabinet. The external circuit fan draws in cool ambient air from the outside, blows it through the fins, where the heat is absorbed by the air, which is then forced back outside.
For external, internal, roof-mounted or any other mounting position, Mini heat exchangers partial mounting
Separate connection of external and internal fans
Simple cleaning of the exchanger core while mounted. Simple removal of exchanger core for wet cleaning (except for the Mini-heat exchanger)
