Integrally geared centrifugal compressors represent the latest technology, offering significant advantages over outdated, less-efficient and more costly compressor designs. These advantages are inherent in the centrifugal design and are further enhanced by Ingersoll Rand's 60+ years of centrifugal expertise.

  IR Engineered Centrifugal Compressors Other Compressors

  • No wearing parts requiring regular replacement
  • Oil filter elements and seal gas filter elements are easily replaced online
  • Require regular maintenance, such as replacement of piston rings, gland packing and valve plates
  • Result in high operating expenses and significant machine downtime

Oil-Free Process Gas
  • 100% oil-free
  • Prevent contamination of system
  • Meet strict downstream requirements
  • Oil filters must be installed at discharge
  • Potential for oil carryover to foul the process

No Pulsation
  • Pulsation-free and require no dampers
  • Require the use of large pulsation dampers to reduce pressure fluctations

Optimum Control
  • Feature inlet guide vane control plus bypass for consistent gas delivery under all conditions
  • The use of cylinder unloading for stepped flow control can result in complicated process control due to sudden changes in capacity

Compact Installation Footprint
  • Capable of handling substantially higher volumes of gas in one or two small casings for a smaller overall package
  • May have 4 or 6 cylinders requiring more space for installation

No Vibration
  • Essentially vibration-free
  • Require only a pad suitable for supporting the static weight of the package
  • Require large and deep foundation to handle heavy weight and unbalanced forces
  • Precautions must be taken to prevent transmission of vibration to other equipment
