Sundyne BMC API 617 / ISO 10439 Base Mounted Integrally Geared Process Gas Compressors

Reliable and economical, Sundyne API 617 / ISO 10439 base mounted integrally geared 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 BMC API 617 – Base Mounted Horizontal Compressor line features single-stage integrally geared centrifugal designs that process engineers utilize 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 850 acfm (1,450 AM³/hr)
  • Maximum working pressure 1,440 psi (100 bar)

Built to meet exacting API-617 / ISO 10439 standards, the BMC 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.
