Frictionless compressors make new revolutions in air-conditioning, refrigeration. The design of these compressors is clearly innovative, elegant, and efficient, and all indications are that it is a quality product. Here we discussed how frictionless compressor technology is proven more energy efficient and reliable in comparison to traditional centrifugal compressors. Originally, it was designed and optimized to take full advantage of magnetic-bearing technology where a digitally controlled magnetic bearing system, consisting of both permanent magnets and electromagnets, replaces conventional lubricated bearings. Magnetic-bearing centrifugal chillers use a permanent magnet synchronous compressor motor.  Such a motor has a significant efficiency increase over an induction motor, especially at low motor speeds, as shown in the figure above.  Instead of physical bearings, magnetic levitation makes for a virtual frictionless operation. The motor also does not require oil lubrication; oil in the chiller evaporator creates a decrease in efficiency over time as the tubes foul, lessening heat transfer. 
They are different because of magnetic bearings, Oil-free design, virtual frequency drive VFD control, smaller and lighter than conventional compressors, and lesser noise. This compressor has the high efficiency, reliability, less maintenance cost & the staff. With help of the digital control system, controlling & monitoring of the work is very easy.
