Process-gas Screw

More than 60 years of experience

Starting in 1952 with the first supply of an oil-free screw compressor unit MAN Diesel & Turbo has set milestones in the field of process gas screw compressors ever since. Not only offer MAN Diesel & Turbo 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 Diesel & Turbo screw compressors also demonstrate its exceptional reliability at even the most critical conditions. MAN Diesel & Turbo 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-Injected Process Gas Screw Compressors

Oil-free process gas screw compressors

MAN Diesel & Turbo’s 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 Diesel & Turbo 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 Diesel & Turbo 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 Diesel & Turbo 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.

 Features & Benefits

  • High robustness and availability
  • Excellent part load performance
  • Suitable for liquid injection
  • No lubricant contact with process gas

Typical Performance Data

  • Suction flow rates up to 100,000 m³/h
  • Discharge pressures up to 50 bar

Oil-injected process gas screw compressors

As a result of intensive R&D efforts MAN Diesel & Turbo has developed its new oil-injected process gas screw compressor series CPO. Drawing from its vast experience in oil-free process gas screw compressors MAN Diesel & Turbo know exactly the demanding requirements from customers in the oil & gas as well as petrochemical industry. Knowing that there is no substitute for experience MAN Diesel & Turbo went into a close cooperation with its former affiliate GHH Rand being widely recognised as a global leader for oil-injected screw compressors for over 60 years. By uniting the exceptional competencies of both MAN Diesel & Turbo and GHH Rand it is guaranteed that the new CPO series will set new standards for oil-injected process gas screw compressors.

  • High robustness and availability
  • Built-in slide valve allows for excellent economic control of volume flow
  • Perfect compatibility of lube oil and process gas by customized oil selection
  • Oil carryover down to 1ppm_wt

Typical Performance Data

  • Suction flow rates up to 4,700 m³/h
  • Discharge pressures up to 25 bar
