What is a Brazed Plate Heat Exchanger?
A Brazed Plate Heat Exchanger (BPHE) is a compact, durable type of heat exchanger made by permanently fusing together multiple thin, corrugated metal plates using a brazing material in a high-temperature vacuum furnace.
Unlike the gasketed plate heat exchanger, which can be opened for cleaning, a BPHE is a single, sealed unit with no gaskets, bolts, or a frame. This makes it ideal for high-pressure and high-temperature applications where a leak-proof seal is critical.
Simple Analogy: If a gasketed plate heat exchanger is like a paperback book where you can remove pages, a brazed plate heat exchanger is like a hardcover book where all the pages are permanently glued to the spine.
