Ejector Systems

  • Rough to medium vacuum, (1013 to 10-3 mbar)
  • Compression from momentum transfer
  • Optimally efficient at a single point
  • Multiple stages
  • Single stage compression ratio (CP) of typically 6:1
  • Maximum practical CP of 12 for steam (and 5 for air)
  • CP of 100,000:1 with 6 stages

Multi-stage ejectors are used to evacuate and maintain the vacuum in many industrial processes – degassing, desalination, deodourising, distillation columns, evaporation, fractionating, freeze drying, turbine condensing, vacuum cooling etc.

Applications are not limited to steam, LVI also offers water, gas and air operated ejectors for a wide variety of applications throughout the process industries.
