How it works

compabloc plate heat exchanger

The cold and hot media flow alternately in welded channels between the plates.

Each medium flows in a cross-flow arrangement within each pass. For multi-pass unit, the media flow in countercurrent.

The flexible flow configuration makes both sides keeping the best thermal efficiency. And the flow configuration can be rearranged to fit the change of the flow rate or temperature in the new duty. 


☆ Plate pack is fully welded without gasket;

☆The frame can be disassembled for repair and cleaning;

☆ Compact structure and small footprint;

☆ High heat transfer efficient; 

☆ The butt welding of plates avoid risk of crevice corrosion;

☆ Short flow path fit low-pressure condensing duty and allow very low pressure drop;

☆ A variety of flow form meets all kinds of complex heat transfer process.
