Paul Mueller Company's semi-welded plate heat exchanger is ideal for solution chilling and refrigerant condensing in refrigeration applications.

The plate pack uses welding cassettes (two plates welded together). The refrigerant side is contained within the welded portion of the cassette, including the welding of the solution port. Gaskets seal the secondary side, making the plate pack easy to disassemble and clean.

The welded cassettes are designed for optimum gasket sealing. Higher pressure improves the sealing of the gaskets.
