Traditional centrifugal compressors use roller bearings and hydrodynamic bearings, both of which consume power and require oil and lubrication system. This can be overcome by the introduction of new compressor technology called frictionless compressor technology. The frictionless compressor technology is compressor with the application of magnetic bearings and permanent magnet synchronous motor. In frictionless compressor instead of roller bearings and hydrodynamic bearings, magnetic bearings are used. Magnetic bearings consume less power and there is no need for oil and lubrication systems. Permanent magnet brushless synchronous motor has permanent magnet instead of copper windings.
After 10 years of development, magnetic bearing compressors offer economic, energy, and environmental benefits. Chief among them are increased energy efficiency, the elimination of oil and oil management and considerable less weight, noise, and vibration. This is initial mid-range package offers centrifugal compression efficiencies previously reserved for large tonnage systems only. This compressor has high reliability, efficiency, less maintenance cost and staff. With the help of digital control system the controlling and monitoring of work is very easy. The frictionless compressor technology makes new revolutions in the field of air conditioning, refrigeration etc..
