Compact

Compact

Counter-flow arrangement for maximal heat transfer and efficiency in asymmetrical applications, normally gas-to-liquid.

Compact is made in stainless steel 316L/1.4404 with copper and in most cases nickel as optional brazing material. The plates are stacked together creating alternating high-volume flow channels (side B, with low pressure drop) and lower-volume flow channels (side A, with higher pressure drop).

All connections are integrated into the heat exchanger. No outside housing or casing is required.
Compact is complete with a condensate connection enabling condensate in the gas medium in side B to drain easily from the heat exchanger.
Compact has an even higher thermal efficiency than Cross due to its compact design and large heat transfer surface.The thermal efficiency for the gas side can often exceed 95 %.

The vacuum-brazing process creates a very large number of brazed contact points between each plate, delivering superior mechanical strength.

Compact is the perfect solution for high-pressure gas applications (up to 25 bar in some versions).
Both vertical and horizontal gas flow is possible with Compact.

The Compact design is currently available in three different plate sizes:
