Brazed Plate Heat Exchangers

Overview

Brazed plate heat exchangers use copper or nickel as brazing material, welded in vacuum furnaces. They feature compact structure, light weight, high pressure capacity, and high heat transfer efficiency (>80%). Compared to gasketed types, they eliminate gaskets for better sealing and wider operating ranges. Copper-brazed models handle up to 30-45 bar, nickel-brazed up to 20 bar, temperatures up to 200-250°C. Plate materials are typically 304 or 316L stainless steel. Widely used in refrigeration (evaporators/condensers), HVAC, hydraulic oil cooling, floor heating. Volume is only 20-30% of shell-and-tube equivalents.
