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

Applications

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, Edwards also offers water, gas and air operated ejectors for a wide variety of applications throughout the process industries.
