GIG Karasek - Model TVR - Thermal Vapour Recompression System
FromGIG Karasek GmbH
The thermal vapor recompression (TVR) builds on the same principle as the mechanical alternative, but uses only a portion of the resulting vapor for heating the system. The compression of the steam for heat recovery takes place in a steam jet pump. This is usually designed for a specific operating point and works on the jet pump principle. A certain amount of steam, the so-called motive steam, is required for the operation of a thermal vapor compressor. The resulting energy savings correspond in many cases in about an additional evaporator stage.

- no moving parts
- low wear
- high operational safety
- less / less investment costs
- simple and effective design
- The main product is water or water with a negligible content of organic substances
- The distillate can easily be vaporized to supply the vapors to the ejectors
- The heating medium is available at the required temperature level
- Moderate difference between upper and lower temperature
The main advantage of the thermal vapor recompression is thus improved steam economy for a moderate investment cost, which is lower than that for an additional evaporation stage.
