Efficiency Advantage - Compressor Design

• 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

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