In Copper Brazed (CB) heat exchangers, the surfaces used to provide heat transfer from one medium to the other are thin, corrugated stainless steel plates stacked on top of each other. The two media are sealed within the plate pack by a brazed copper seal around the edge of the plates.
The GEA PHE Systems GP Series is an innovative Plate & Fin construction designed for high heat transfer and endurance. By combining brazed plate and fin technologies, an ultra-compact heat exchanger is possible that is 30% to 60% smaller than conventional designs and provides higher performance.

Making stainless steel brazed heat exchangers a success Moreover, the life-cycle cost of a brazed plate heat exchanger can often be half that of a corresponding gasketed solution. Tomas says SWEP can also target new applications where nickel and copper cannot be used. Höganäs' stainless steel brazing filler is highly durable and can withstand difficult conditions that copper cant.
