CENTRIFUGAL CHILLERS (TURBOLEV-KSM/KDM)

Single stage compressor design
Optimized impeller designs
High efficiency, refrigerant cooled motors
Free standing Variable Frequency Drive
Frictionless compressor bearings minimize efficiency Loss
Easily meeting BEE 5–Star Rating : ISEER 9.87 to 10.0
IPLV @ AHRI conditions < 0.30 IkW/TR
Capable of operating at a high lift conditions, such as high condensing or low leaving chilled water

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
Combination of soft start function and variable speed drive combined, limits inrush current at Start up

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
