General information

The Airec Compact exchanger is an asymmetric brazed plate heat
exchanger consisting of stainless steel plates brazed together with
copper or nickel. The Compact family consist of six different mod-
els, Compact 25, 26, 36, 37, 71, 72 and 73 which refer to the plate
size, for further measurements, please see respective Product
Data Sheet on www.airec.com. The Compact family consist of sev-
eral types depending on material combinations, pressure ratings
and functions.

Connections
All connections on the Compact are brazed in the general vac-
uum-brazing cycle, which gives a very strong seal between the
connection and the cover plates. However, do not use excessive
force which can damage the connection.
The Compact are available with connections adapted to the
model/size, for exact measurements, please see respective Prod-
uct Data Sheet on www.airec.com.
The Compact are available with threaded ISO-G connections for
liquid and condensate connection. The gas connections are of
type welding/brazing connection.
