Brazed plate heat exchangers

These are built from a stainless steel plates pack with no gaskets and welded together by copper brazing in a vacuum furnace.
The plates can have two different corrugations:
  • "H" - High efficiency, high pressure drop
  • "L" – Low efficiency, low pressure drop
The selection of the most suitable model and corrugation for the requested application is made by our technical staff using a calculating software.
Among the advantages of the brazed plate heat exchangers are the following:
  • High pressures and temperatures
  • Small dimensions
  • Low price
All our brazed plate heat exchangers are 1-pass and operate in parallel flow. They can be used both for heating and chilling, using any kind of water also with glycol.
For the verification of compatibility with other fluids contact our technical office.
