Multiple air channels formed by fins generate heat transfer between the exhaust air and the fresh air, resulting in heat recovery. This is the sensitive type. There is heat transfer between the two air streams, but there is no moisture transfer. It is advantageous not to have moisture transfer for this type. Exhaust air and fresh air pass through the heat exchanger mainly from opposite directions.

Technical values such as heat recovery, temperature efficiency, air pressure drop on both sides and the risk of water freezing in winter are calculated in-house using specially developed software.

The width (W) and height (H) of the heat exchangers are fixed, while the length (L) and pitch (h) may vary.

Types L, U, etc. are available for the airflow side.
The fins are made of aluminium as standard. On request, marine alloy aluminium, epoxy or hydrophilic industrial pre-coating can also be used for the fins. Covers can be manufactured in galvanised sheet metal, or in aluzinc and aluminium alloy on request.
