Sundyne LF 2X80 API 617 / ISO 10439 Base Mounted Integrally Geared Multi-Stage Process Gas Compressors


Reliable and economical, Sundyne integrally geared multi-stage compressors

Process gas compressors are the heart of the process. Their reliability directly impacts the productivity and the efficiency of the midstream, hydrocarbon processing or chemical plant.

The Sundyne LF 2X80 is a compressor that can be outfitted to meet exact API and ISO standards, or it is can be economically engineered as a fit-for-purpose compressor.  The 2X80 features from one to four stages of centrifugal compressors on a single gearbox. These designs save valuable space and reduces energy costs. Process engineers utilize these multi-stage compressors for midstream, hydrocarbon processing and chemical manufacturing applica­tions including mole sieve dehydration, regeneration of the demethanizer, waste gas, hydrogen recycle and specialty chemical production.  Each compressor is custom built to provide pulsa­tion- and vibration-free operation, and to deliver oil-free process gas with zero emissions.

  • Flows to 6,000 acfm (10,200 AM³/hr)
  • Maximum working pressure 1,440 psi (100 bar)

With a design heritage meeting API-617 / ISO 10439 standards, the LF 2X80 will run continuously for 5 years without costly maintenance or an overhaul. These horizontally configured compressors are ideal for skid packaging — due to their unique modular baseplate — and are easy to install into any process environment. Packaging and instrumentation are customizable to meet your needs and specifications. NACE compliant Sundyne compressors do not rust or corrode.

Sundyne gas compressors provide the performance envelope, the feature set, the reliability ratings and the uncompromising efficiency needed to address the Best Efficiency Point (BEP) for any process gas application in the most demanding environments.


  • Mole sieve dehydration
  • Regeneration of the demethanizer
  • Waste gas
  • Hydrogen recycle
  • Specialty chemical production
  • Fuel gas boost for power generation

Proven to be reliable, safe, compact and efficient, the Sundyne line of integrally geared multi-stage compressors provide a number of operational benefits:

  • One or two stage in-line overhung integrally geared compressor
  • Single gearbox and motor saves energy and space
  • Maximized up time
  • Saves space-25% the size of competing reciprocating, barrel, rotary screw and diaphragm compressors
  • Continuous operations for 5 years with no overhaul
  • Optimized compressor engineering to meet the BEP – Best Efficiency Point to save energy through efficiency
  • Smaller gearbox housing to reduce weight and cost
  • Can be built as a fit-for-purpose compressor reducing instrumentation and complexity to meet customers needs
