Oil Free Screw Compressor Packages

Complete package systems for process critical applications

There are many situations where oil free technology presents the best approach. Oil free screw compressors are available in different configurations and materials providing the most compact arrangement, to allow the handling of gases with high levels of liquid, dirt and particulates. There configurations are eminently suitable for use with hazardous or corrosive gases, or where contamination is an issue.


Oil Free Compressor Range

Howden Oil Free Screw Compressor packages are used in processes such as:

  • Vapour recompression
  • Gas Liquefaction
  • Flare Gas Recovery
  • Gas Gathering
  • Sour Gas Handling

The oil free compressor range is able to provide gas compression to up to discharge pressures of 45 bar (653 psi) and 15 bar (217 psi) differential pressure. Available in 10 models the range covers flows up to 92,000 m3/h (54,150 cfm).
