Compresseurs d’air et de gaz centrifuge MSG-2/3
Fonctionnalités
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 70 to 3800 m3/min (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

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.

Advantages of Centrifgual Compressor Technology
The Right Compressor for Your Needs
MSG centrifugal compressors are exceptional by design.
- One, two or three rotors, up to six stages per gearbox
- 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
