The MAN RG integrally geared centrifugal compressor features a multi-stage arrangement with up to five pinions and up to ten impeller stages. Intercooling is possible after each stage, which lowers power needs, and individual process stages within one casing are also possible, which makes for more efficient operation. All shafts are equipped with maintenance-free tilting pad bearings. This enables a very compact design, compression of a wide range of gases, and a high-pressure ratio. Improved impeller design, pinion speeds, and aerodynamics guarantee the highest level of efficiency.
