MSG® LMAC™ 20 Centrifugal Air Compressor

Features
AIR SEPARATION PROCESS
The volumetric composition of dry atmospheric air is ~78% nitrogen and ~21% oxygen, with the remaining ~1% being made of argon, carbon dioxide and trace amounts of other gases. These gases can be separated in an air separation process where the air is compressed, cooled and separated by molecular weight in a “cold box.” Once separated, the gases are again compressed for storage, transportation, or further processing. Ingersoll Rand has the technologies and resources to provide the main air compressor (MAC), booster air compressor (BAC), nitrogen gas compressor (GAN), nitrogen recycle compressor (NRC), and argon gas compressors.
The MSG LMAC is designed specifically to fulfill the role of the MAC with optimized aerodynamic efficiency. Interstage coolers are implemented after each stage of compression to remove the heat of compression and achieve high isothermal efficiency. The MAC is the heart of the ASU; its efficient and reliable operation is critical to the success and viability of the ASU project.
HIGHLY EFFICIENT DESIGN
MSG LMAC compressors are designed to deliver peak performance throughout the entire compressor operating range and feature:
- Custom, 5-axis milled impellers for process-specific aerodynamic designs
- Inlet Guide Vanes (IGV)
- High-efficiency intercoolers and optional aftercooler
ROBUST MECHANICAL DESIGN
MSG LMAC compressors are designed to withstand the rigors of a long and demanding service life with:
- Tapered rider ring thrust collars to absorb loads at low speed
- Tilting pad radial bearings
- AGMA 13 rated bullgear and pinion gears
STANDARDIZED COMPRESSOR PACKAGE
The highly accessible, standardized design allows for shortened delivery times and ease-of-installation/maintenance by providing:
- Standard engineering drawings
- Package-mounted intercoolers and terminal box/MAESTRO™ Universal control system
- Horizontally split gearbox
- Side-mounted lubrication console with duplex oil filters standard
- Compressor sub-base
ADDITIONAL APPLICATIONS
In addition to air separation, the MSG LMAC can be deployed for efficient, reliable service in several other applications, including:
- Aerospace
- Automotive
- Electronics
- Fertilizer
- Glass
- Life Sciences
- Mining
- Petrochemical
- Pharmaceuticals
- Power Generation
- Steel
