Air-To-Air Heat Exchangers

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…
