Copeland, St. Louis, Missouri, releases its new oil-free centrifugal compressor to market, delivering high-lift performance, reliability, and efficiency enhancements in demanding chiller applications. The compressor features aero-lift bearing technology, enabling the compressor shaft to self-levitate and operate independently, without friction or reliance on electromagnetics, complex controls, or proximity sensors.
The new oil-free centrifugal compressor platform is being developed for the 50- to 200-ton capacity range and is optimized for use with the next generation of lower-GWP A2L and A1 refrigerants such as R-1234ze, R-515B and R-513A.
