Process-gas Screw

More than 60 years of experience

Starting in 1952 with the first supply of an oil-free screw compressor unit MAN Energy Solutions has set milestones in the field of process gas screw compressors ever since. Not only offer MAN Energy Solutions the widest range of screw compressor sizes in the market with rotor diameters starting from 102 mm to 816 mm. With the highest referenced discharge pressure (51.5 bar_a) and greatest in-field volume flow (77,000 m³/h) MAN Energy Solutions screw compressors also demonstrate its exceptional reliability at even the most critical conditions. MAN Energy Solutions' screw compressor units have proven high availability factors over more than 100,000 hours of trouble-free operation in continuous refinery service and other fields of applications such as:

  • Mining
  • Iron and steel mills
  • Chemical complexes
  • Petrochemical industry
  • Oil fields
  • Oil-Free Process Gas Screw Compressors

Oil-free process gas screw compressors

MAN Energy Solutions' capabilities in the field of oil-free screw compressors are unique: Over 60 years of experience, more than 2,000 compressor units in the field, proven trouble-free availability of more than 100,000 continuous operating hours underline the exceptional quality of MAN Energy Solutions oil-free screw compressors.

Designed for suction volume flows from 200 up to 100,000 m³/h, suction pressures down to 0,1 bar and discharge pressures reaching above 50 bar, the robust process-gas screw compressors offered by MAN Energy Solutions can handle highly contaminated gases and gas mixtures that would normally shorten the availability and life time of other types of compressors. Wide fluctuations in gas composition and associated molecular weight do not influence a screw compressor's mechanical behaviour. Relatively low tip speeds allow both the compression of dust laden gases as well as the injection of liquids into the compression chamber for cooling and washing.

MAN Energy Solutions can offer a wide range of shaft seal arrangements to adapt the process gas screw compressors to any application. The modular design of the compressor package allows for perfect adaption to any customer specification or space restrictions.
