. CB77 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. Typical applications - HVAC heating/cooling - Refrigerant applications - Industrial cooling/heating - Oil cooling Working principles The heating surface consists of thin corrugated metal plates stacked on top of each other. Channels are formed between . plates and corner ports are arranged so that the two media the flow through alternate channels, usually in countercurrent flow for the most efficient heat transfer process. Examples of connections 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.
