CB300 - Brazed Plate Heat Exchanger

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, always in countercurrent flow. The media are kept in the unit by a brazed seal around the edge of the plates. The contact points of the plates are also brazed to withstand the pressure of the media handled.

Standard design

The plate pack is covered by cover plates. Connections are located in the front or rear cover plate. The channel plates are corrugated to improve heat transfer efficiency and to make them rigid.

Advantages of brazed plate heat exchangers in Industry and HVAC&R

The Alfa Laval Brazed plate heat exchangers (BHE) have several advantages over traditional heat exchangers in Industrial and HVAC&R applications.

  • - The high heat transfer efficiency of the BHE makes it extremely compact and also easy to install in places were space is limited.
  • - The unit has no gaskets and is therefore suitable in applications were temperature and/or pressure is high e.g. in district heating.
  • - The Alfa Laval supply system reassures that, no matter were you are on the globe, the BHE units are available with a very short delivery time.
