Advantages of our EVO®-Gas Products

  • High operation reliability – designed for gas applications in continuous operation
  • Includes all advantages of our built-in EVO® technology
  • Each compact unit is tested as a complete system before leaving our factory
  • No leakages due to reduced piping and connections as well as sealing with O-rings (Viton®)
  • Optimized compact design with very low space require­ments
  • Drive options: Belt drive, direct drive
  • Easy selection with our "ROTORCOMP SIZING GAS" prediction software.
  • Simplified service and maintenance

The outset components are included in each EVO®-Gas compact unit:

  • Rotary screw gas end
  • Thermostat regulator for oil
  • Oil pre-separator and receiver tank
  • Minimum pressure valve
  • Oil final separator cartridge/box
  • Oil level sight glass
  • Oil filter cartridge/box

Ultimate efficiency and reduced noise through

  • High volumetric output due to
    • Reduced internal leakage
    • Improved suction port efficiency giving reduced internal losses
    • Adapted compression ratio to inlet- and outlet pressure
    • Optimized oil injection point for increased intake pressures.
  • Low power consumption due to
    • Optimized torque characteristics and reduced internal friction
    • Adapted compression ratio to inlet- and outlet pressure
    • Improved outlet port with lower pressure losses
  • Reduced noise and low vibration due to
    • Smooth rolling of the rotors with new ROLLING PROFILE®
    • Optimized outlet port
