Thermal Vapour Recompression

Evaporators with thermal vapour recompression technology use a part of the vapours to heat the unit. To this end, vapours are absorbed by an ejector and the vapours recompress up to a higher pressure. The ejector is usually designed for specific working points and works on a jet pump principle. It has no moving parts, which guarantees a simple construction and safety in operation.


Compelling arguments for thermal vapour recompression (TVR):

  • The top product is water only, or water with negligible content of organic substances
  • The distillate can be easily evaporated in order to provide motive vapours for the ejectors
  • The heating agent is available at the necessary temperature level
  • Moderate difference between top and bottom temperature
