Wide selection of frames and cylinders for different pressures, flows, and applications.
Variable Volume Control Pockets (VVCP) for capacity control and balancing.
Available provisions to prevent leaks of toxic/corrosive gases.
Low power consumption for high-ratio compression applications using multiple stages and inter-stage cooling.
Parts availability for common components.
Expansive service network.
Detailed simulation softwares and responsive support centres.
Disadvantages of Reciprocating Compressors
Multi-stage units require a lot of interconnected piping and are capital intensive, both on materials and assembly.
Reciprocating movement tends to create relatively higher vibration than rotation, and can cause stress on components.
Multiple suction and discharge valves on each cylinder.
Operating procedures typically specify VVCP’s can only be adjusted on a de-pressurized unit.
Very low tolerance for liquids in the gas stream.
Discharge gas will have lubrication oil in it.
What’s NEXT for Reciprocating Compressors
EVCPs, or comparable technologies. Internal capacity control while operating – similar to a slide valve – helps provide flexibility to an otherwise static design point. The technology exists, and it is a matter of field testing and establishing successful run-time.
Expanding supply chain options. GE recently announced that their compression lines have been sold and established as Cooper Services, with the focus being servicing the existing fleet. Competition is critical to a healthy supply chain, and we will push to bring more options to market.
