Process Gas Centrifugal Compressors

Process Gas Axial and Centrifugal Compressors according to API-617 as well as customer's specification are supplied as fully packaged compressor skids with all auxiliaries, such as DGS panel, lube oil system, anti-surge valve and control system and all other compressor instrumentation & control systems in both single shaft and integrally geared configurations.

Single shaft centrifugal compressors are employed in a variety of applications with capacities well over 500,000 m3/h and pressures of around 450 bara such as:                                     

                                                                                                               Process Gas Centrifugal


  • Various gases for chemical and petrochemical plants
  • Recycle gas for refineries and synthesis plants
  • Synthesis gas for ammonia and methanol plants
  • Recycle gas in refineries
  • Circulator in petrochemical plants
  • Natural gas feed, feed air and refrigeration in ammonia plants
  • Natural gas transmission
  • Air, nitrogen and oxygen in air separation plants
  • Natural gas gathering


Single shaft centrifugal gas compressors are the ultimate choice when high RAM (Reliability-Availability-Maintainability) figures are expected. Such compressors are usually operated un-spared in the most harsh plant environment. Hence, the compressor block as well as all auxiliaries must be chosen with no compromise and ample redundancy, enabling the machine to be operated and maintained without interruption. Havacaran has the knowledge and the expertise to supply such compressors on the MODULAR PACKAGING approach from most reliable sources.

Havacaran offers a wide range of single shaft centrifugal gas compressors to API-617, both in axial split and radial split configurations, as follows:
