Sundyne Compressors
Over the years, Sundyne compressors have evolved from the reliable, integrally geared line-mounted compressor (LMC) technologies that we built our name on to the API-617 rated base-mounted (BMC) and Pinnacle multi-stage units that we sell today.

Integrally Geared Centrifugal Single Stage Heavy Duty Compressor
Sundyne Corporation single-stage centrifugal compressors typically provide the same performance range as multi-stage, piston driven positive displacement compressors, allowing for smaller, easier to maintain equipment that requires overall less energy to keep running.

Sundyne Standard
In the 1960s, Sundyne Corporation (then Sundstrand Fluid Handling) emerged as the leading expert for integrally geared centrifugal compressors.
