Brazed plate heat exchanger

Brazed plate heat exchangers are widely used in refrigeration plants. They are normally used to transfer heat from the refrigerant - the primary fluid - and from water or brine as the secondary fluid.

Units in the Alfa Laval AC series of copper-brazed heat exchangers are mainly used as:
Evaporators for dry expansion and cooling water
Condensers for rejecting or recovering heat to water
De-superheaters for partial heat recovery to water
Economizers for cooling liquid refrigerant and super-heating vapour refrigerant.
