Gas Compression

Russian

Under the Rosscor brand and now Colfax Fluid Handling‚ we have been the leading OEM packager of Howden screw compressors for our gas compression systems since 1960. In a gas compression system‚ compression is achieved by the intermeshing of two helical rotors contained in a suitable casing. These helical rotors force the gas into smaller and smaller space‚ compressing the gas and generating the pressure required.

The Howden oil injected twin screw compressors‚ models XRV and WRV‚ are positive displacement rotary design. As such‚ they have the characteristics and stability of reciprocating compressors and offer the following advantages over reciprocating technology:

  • Reduced physical size
  • Fewer moving parts
  • Low vibration
  • Extended operating life cycle
  • Designed for direct drive
  • Suction or discharge valves and unloaders are not typically required
  • Constant inlet volume draw
  • Is not affected by gas density or composition
  • Meets varying differential pressure requirements
  • Low pulsation
  • Low power consumption

Typical gases or refrigerant handled by the Howden range of oil injected screw compressors include:

Refrigerants

  • R717
  • R134a
  • R404A
  • R407C
  • R410A
