Brazed Plate Heat Exchanger (BPHE)

This image displays a modern brazed plate heat exchanger (BPHE), a highly efficient device designed for transferring heat between two fluids without them mixing. The unit features a series of corrugated stainless steel plates, brazed together with copper (visible as the golden-brown edges) to form independent flow channels. It has four distinct connection ports – two at the top and two at the bottom – for the inlet and outlet of the two different fluids. Brazed plate heat exchangers are widely used in a variety of applications including HVAC systems (for chillers, boilers), industrial processes, refrigeration, and domestic hot water systems, where their compact size, high thermal efficiency, and robust construction are significant advantages.
