Closed cell sealing strips

Technical information

Functional description

Decentralised secondary air units dissipate cooling loads and heat loads.

The room air is taken in by an EC centrifugal fan and passes through a filter fleece. The air is subsequently heated or cooled by the heat exchanger and eventually supplied to the room as an inducing displacement flow.

Decentralised secondary air units of Type FSL-B-SEK, with heat exchanger, for installation under the sill.
