Kirloskar TURBOLEV® series of chillers uses the principle of magnetic levitation on application of an electric field, adapted to suit the chiller application.
Magnetic levitation, already a proven technology in aerospace, oil and gas exploration and transportation applications, is combined with variable-speed centrifugal compression and supported by digital electronics to run the compressor without any contact between the rotating dynamic and static parts and allows the compressor to operate in a frictionless environment so as achieve the highest efficiencies.
Centrifugal compression offers substantially higher isentropic efficiency compared with other compressor designs. Used most effectively in a centrifugal compressor, a variable-speed drive further enhances part load efficiency. The combination of this technology with magnetic levitation results in a machine with an unparalleled bouquet of benefits - extremely quiet operation very high efficiency without the need of lubrication which is so essential in conventional compressors.

Efficiency Advantage - Oil Free Design
- Over a period of time, oil in chillers with lubricated compressors tends to carry over to the heat exchangers and coat the heat exchanger tubes and reduce heat transfer, resulting in a deterioration in chiller efficiency.
- An ASHRAE determined the quantity of oil as a percentage of refrigerant in older chillers and found the average to be 12.88%. The study determined that even 3.5% of oil equated to an 8% efficiency loss.
- Thus, oil free compressors stand to benefit to a large extent due to the absence of oil
Starting Current Advantage:
- Starting Amps - 2 Ampere as against 200 ~500 A of conventional chillers
- There is gradual increase in the voltage until the DC bus reaches the up trip voltage
