Air curtains

have an integrated heat exchanger. Our heat exchangers are manufactured for all kinds of heating media: e.g. low-pressure hot water – LPHW 70/50°C for normal temperatures and 60/40°C for low temperatures (other temperatures available on request), DX heat exchanger for use with heat pumps, electric heat exchanger for operation with 400V electrical power. Heat exchangers for steam are available on request. To save energy, warm door air curtains are installed inside a room, above or next to the door. The air stream prevents exchange of air and temperature and, despite the door being open, creates a zone of comfort in the entry area. Therefore, the staff do not become ill from standing in unpleasant cold draughts.
