This is a custom built refurbished compressor for a chemical plant in South Carolina. They have a nitrogen booster skid but did not have a spare compressor. We built this unit to meet their specific application needs and will also be handling the overhaul of the installed unit. This is a BLACKMER® HD362C oil-free, single stage unit. With our stock of used compressor frames, we have the ability to build custom compressor configurations that are fully tested and ready for install. All S&S Technical, Inc. refurbished compressors come with a test certificate and 18-month workmanship warranty.
