Plate-type exchangers are made of corrugated stamped plates. The plates have a 180° orientation in order to create a grid. Fluids are normally routed in a counter-flow pattern. Plates are fused together using a brazing material with a lower melting point that the plate, itself this is normally copper or nickel.The brazing takes place in a vaccum furnace resulting in a robust long lasting joint.

The corrugated surface on the plates creates good turbulent flow to maximise heat exchange and reduce fouling.
Benefits of brazed plate coolers:

▪ High coefficient of heat exchange;
▪ Reduced dimensions and high performance;
▪ High pressure and temperature resistance;
▪ Easy installation
