Features

MSG® INTEGRALLY GEARED CENTRIFUGAL COMPRESSORS

MSG (multi-stage geared) compressors offer outstanding design flexibility. MSG compressors are application engineered with numerous available configurations:

  • Flows from 4,200 to 230,000 m3/h (2500 to 135,000 CFM)
  • Input capacity to over 18,650 kW (25,000 hp)
  • Discharge pressures to 100 barg (1450 psig)

FEATURES

Oil-Free Air and Gas

  • Prevents system contamination
  • Reduces the potential for compressed air pipeline fires caused by oil carryover
  • No costly waste disposal associated with oil-laden condensate
  • Eliminates the expense and maintenance of oil separation filters at the discharge

High Reliability

MSG centrifugal compressors are designed to be extremely reliable due to:

  • Conservative high-quality gear design
  • Long-life pinion bearing design
  • Thrust loads absorbed at low speed
  • Stainless steel compression elements

Low Compressor Operating Life Cycle Cost

MSG centrifugal compressors provide better overall operating efficiency than positive displacement or other centrifugal compressors.

  • Excellent efficiencies at full load, part load and no load
  • Low maintenance cost
  • Increased uptime from high-reliability design (limits the need for multiple unit installations for basic reliability reasons)
  • No sliding or rubbing parts in the compression process that can cause wear and thereby efficiency loss 

APPLICATIONS

Engineered Air Applications

Gas Compressor Applications

class 0 centrifugal

ISO Certified Class Zero

1. Our MSG TURBO-AIR centrifugal compressor product line has been engineered to produce oil for more than 60 years
2. This certification officially acknowledges the ability of our compressors to produce 100 % oil free air, providing our customers with enhanced quality assurance

Easy Operation/Maintenance

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

Simple Installation

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

MSG centrifugal compressors are exceptional by design.

1. One, two or three rotors, up to six stages per gearbox
2. Horizontal splitline(s) for easy access to parts

 

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
