Brazed Plate Heat Exchanger General information Alfa Laval introduced its first brazed plate heat exchanger (BHE) in 1977 and has since continuously developed and optimized its performance and reliability. Brazing the stainless steel plates together eliminates the need for gaskets and thick frame plates. The brazing material seals and holds the plates together at the contact points ensuring optimal heat transfer efficiency and pressure resistance. The plate design guarantees the longest possible life. The design options of the brazed heat exchanger are extensive. Different plate patterns are available for various duties and performance specifications. You can choose a standard configuration BHE, or a unit designed according to your own specific needs. The choice is entirely yours. Liquid/liquid applications: - HVAC heating/cooling - Process heating/cooling Working principles The heating surface consists of thin corrugated metal plates stacked on top of each other. Channels are formed between the plates and corner ports are arranged so that the two media flow through alternate channels, usually in countercurrent flow for the most efficient heat transfer process. Standard design The plate pack is covered by cover plates. Connections are located in the front or rear cover plate. To improve the heat transfer design, the channel plates are corrugated. Particulars required for quotation To enable Alfa Laval's representative to make a specific quotation, specify the following particulars in your enquiry: - Required flow rates or heat load - Temperature program - Physical properties of liquids in question - Desired working pressure - Maximum permitted pressure drop External threaded Welding Compact flanges
