Gas jet compressor

Using a gaseous motive medium, gas jet compressors compress gases or vapors with a large pressure differences.

Applications :

Gas supply

  • Mixing of evaporated liquid gases (propane, butane) with air.
  • Conveying and mixing of natural gases.
  • At gas storage tanks and under- ground high-pressure sensors.

Chemical industry

  • At loading points for liquid mineral oil products to prevent emissions.


  • As a controllable unit fitted with a nozzle needle.

Steam jet compressor

Using water vapor as motive medium, steam jet compressors compress gases and/or vapors with large pressure differences.

Applications :


  • Compression of low-pressure steam with high-pressure steam as motive medium for feeding into medium pressure systems.

Chemical industry

  • Heating of distillation columns.

Foodstuffs- and chemical industry

  • As components of evaporating systems, e.g. for milk, fruit juices, waste water, chemicals, sea water.
  • To cool and concentrate liquids.

Paper industry

  • In steam- and condensate systems of single- and multi- cylinder machines.
  • To increase pressure in steam systems/to increase performance capacities of paper machines.
  • In connection with steam boxes to utilise low-pressure steam


  • Re-utilisation of vapors coming from the boiling process.


  • Steam recovery in “TMP” systems.

Petrochemical industry

  • Removal of column head vapors.


  • As a controllable unit fitted with a nozzle needle.

Liquid jet gas compressor

Using a liquid as motive medium, liquid jet gas compressors compress gases or vapors with large pressure differences. There is a special ejector design for mixing air or other gases with the motive liquid or for aerating waste water. These ejectors operate at a high gas/liquid mass transfer rate with simultaneous intensive mixing of the liquid itself.
