Seminar On Frictionless Compressor Technology- Mechanical Seminar Topic


A new compressor technology introduced in international Air-Conditioning, Heating, Refrigerating, Exposition (AHR  Expo).This technology is designed and optimized take full advantage of magnetic bearing technology,the compressor was awarded the first AHR  Expo innovation award in energy category.traditional centrifugal compressors use roller bearings and hydrodynamic bearings,both of which consume power and require oil and a lubrication system.By using this system we can prevent the lubrication of the bearings and the maintenance cost and pollution decreases.


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 newrevolutions in the field of air conditioning, refrigeration etc. Frictionless Compressor Technology is one of the fast growing Technology in the engineering field.
The Frictionless compressor is also the world’s first totally Oil-Free compressor specifically designed for the Heating, Ventilation, Air Conditioning and Refrigeration (HVACR) industry. The variable-speed centrifugal compression and digital electronic technologies enables the frictionless compressors (nominal 60-150 ton capacity range) to achieve the highest compressor efficiencies, cost effectively, for middle-market, water-cooled, evaporative cooled and air-cooled HVACR applications. The well-proven energy performance advantages of variable-speed centrifugal Compressors are now brought to mainstream middle-market applications through the use of High-speed, two-stage centrifugal compression with integral variable-speed drive. Compressor speed is reduced as the condensing temperature and/or heat load reduces, Optimizing energy performance through the entire operating range from 100% to 20% or below of rated capacity.
Operations to near zero loads are achievable via an optional, digitally controlled, load balancing valve. Centrifugal compressors tend to be more efficient than screw or scroll Compressors, and take advantage of speed control more effectively, but they are usually only availablein larger sizes. By using the smaller shaft, they are able to take advantage of the centrifugal compressor technology in a smaller size than is normally available.

What is frictionless compressor?

  • The frictionless compressor technology  is the compressor with which the application of the magnetic bearings & permanent magnet synchronous motor.
  • In the frictionless compressor instead of the roller bearings & hydrodynamic bearings, magnetic bearings will be use.
  • Magnetic bearing technology is significantly different. A digitally controlled magnetic-bearing system, consisting of both permanent magnets and electro-magnets, replaces conventional lubricated bearings . 


  • When the magnetic bearings are energized, the motor and impellers, which are keyed directly to the magnetic shaft, levitate(Floating).
  • Permanent-magnetic bearings do the primary work, while digitally controlled electromagnets provide the fine positioning.
  • As the levitated assembly moves from the center point, the electromagnets’ intensity is adjusted to correct the position
