Ejector Systems Variable - Flow Ejectors

Variable - Flow Ejectors are based on proven GEA jet pump technology and often used for heat recovery.

GEA steam jet systems have a simple design, they are reliable and require low maintenance.



  • upgrading of waste steam / low-pressure steam
  • heating of evaporators
  • heating recovery from hot condensate

Mode of operation

  • a low pressure steam is compressed to a higher pressure level (driving energy: medium- or high-pressure steam)



  • low maintenance 
  • quickly and easily put into operation
  • decades of lifetime, when a suitable material of construction is chosen
  • can be manufactured from various materials of construction
  • low acquisition costs
  • a motive nozzle needle allows precise adaption on varying mass flow and pressure requirements
