MSG® 25 Centrifugal Air & Gas Compressor

MSG compressors are custom designed and built for individual customer needs for a variety of applications. Our MSG style compressors are manufactured with a highly engineered air flow components, designed for easy, low-cost installation and operation.
  • Impellers: Five-axis milled impellers designed and manufactured with advanced techniques and methods.
  • Vane Diffusers: Optimized design and placement of vanes for greater efficiency.
  • Lubrication System: Autonomous low-pressure lubrication system.
  • Intercoolers/Aftercoolers: Interstage and aftercooler assemblies with water tubes slide out to simplify inspection and cleaning.
  • Advanced Pinion Bearing Design: Designed for extended lifespan and operation under any load.
  • Seals: We offer a wide variety of non-contact and wear-free designs capable of handling numerous different gas processes, which do not require buffer air for an oil-free seal.

Standards Compliance:

  • ISO 8573-1 class 0
  • American Petroleum Institute (API)
  • ISO 9001:2008
  • ISO 14001:2004

Easy Operation/Maintenance

  • State-of-the-art MAESTRO control systems
  • Fully automated operation for any process conditions
  • Machine self-diagnostics
  • Compression elements do not wear or require periodic replacement
  • Accessible horizontally split gearbox for quick inspection
  • Removable intercooler and aftercooler bundles for easy cleaning

Simple Installation

  • Compressor, lubrication system, intercoolers, shaft coupling, coupling guard, interconnecting piping, etc. on a common base
  • Easy installation with no special foundation requirements
  • Easy component accessibility
  • Site connection point flexibility
  • Reduced floor space required
  • Dynamic compression process is pulsation-free, so installation of additional dampening equipment is not required.

MSG centrifugal compressors are exceptional by design.

  • One, two or three rotors, up to six stages per gearbox
  • Horizontal split line(s) for easy access to parts

APPLICATIONS

Engineered Air Applications

  • Industrial gases
  • Instrument air
  • American Petroleum Institute (API) standards
  • Soot blowers
  • Large plant air
  • Power industry related

Gas Compressor Applications

  • Fuel gas boosting
  • Natural gas gathering
  • Hydrocarbon refrigeration gas
  • Carbon monoxide
  • CO2 (wet or dry)
  • Syngas
  • Low molecular weight recycle gas
  • High-pressure nitrogen
  • Landfill gas

GAS FLOW ARRANGEMENT

MSG centrifugal compressors feature an advanced arrangement of gas flow components. Advantages of this arrangement include:

  • Directed gas movement to reduce turbulence induced friction
  • Air is cooled after every stage to provide high isothermal efficiency
