We just completed an overhaul on this Corken FT691-4 compressor for an Air Liquide hydrogen facility in California. After several years of issues with the factory piston rings failing due to heat build up in this dry gas application, we reached out to a channel partner who designs and manufactures reciprocating compressor piston rings and packing. We provided them the operating conditions and worked with them on specific dimensional information. They were able to formulate a custom piston ring material that will perform far better and significantly improve reliability.
We don’t just install new parts and ship it back out.
