Centrifugal Compressors are high-speed mechanical devices that increase the pressure of a gas by reducing its volume. Calnetix Technologies’ Magnaforce™ permanent magnet (PM) motors, with their high efficiency, small size, and high-speed capabilities are ideal prime movers to drive these devices.
Calnetix designs and manufactures these high-speed superior performance compressors utilizing its Powerflux™ active magnetic bearing, Vericycle™ variable speed drive and PM motor technologies. Calnetix’s oil-free bearings enables frictionless operation, which reduces energy losses and allows the system to be hermetically sealed, especially in certain applications, such as hydrogen compression. Coupled with the motors’ variable speed drive, the compressor operates more efficiently at partial speeds and loads than standard compressors.
Calnetix has broad experience in designing PM motor solutions for compressors of all types and environments, including hydrogen. Our field experience encompasses the most demanding conditions in industrial and offshore applications, with units that have set new highs in reliability and efficiency for large HVAC chillers to oil-free compressors.
