KRSP2: Two Stage Screw Air Compressor
Two-Stage Compressors have power advantage of 8 % to 15% over equivalent size single-stage compressors for two key reasons: Inter cooling and Division of Compression Ratio.
Low Operating Costs
Incorporates inter-stage coolant injection which atomizes the cool lubricating fluid into fine mist. This dynamic process rapidly absorbs the heat of compression from first stage and pre-cools the air entering the second stage prior to compression, drastically reducing power costs.
Division Of Compression Ratio
Ina Single stage Compression operating at 100 psig at sea level, the compression ratio is 7.8 to 1 {in absolute terms }. A two-stage compressor operating at the same pressure will have a compression ratio of 2.8 to 1 in each stage { 2.8 is the square root of 7.8} achieving the compressor's power savings.
Apart From Energy saving these series Have following Advantages
- Internal Leakage losses are reduced- Reduced pressure difference across each stage facilitates reduction in leakage loss.
- Extended bearing life – By Dividing the compression ratio across two-stage, the two-stage will significantly exceed the life of the average single-stage compressors. Bearing loads are reduced to 1/3 of single stage.
