TWO-STAGE COMPRESSION: SETTING THE STANDARD FOR ENERGY EFFICIENCY

Compared to single stage compressors, a two-stage is much closer to isothermal compression. This is achieved by injection of fresh oil between the stages which reduces the inlet temperature to the second stage. This lower inlet temperature increases efficiency by reducing the compression ratio between the stages. In addition, leakage between the rotor seals is significantly reduced resulting in outstanding volumetric efficiency.

Two-stage air compressors are closer to the ideal isothermal compression:
• Reduced leakage increases volumetric efficiency
• Saves 10-15% of energy compared to single stage compressors
• Increases flow 10-15% compared to single stage compressors
• Lower pressure differential increases efficiency and reliability
• Low heat load
• Easy maintenance and service
• Lowest life-cycle cost of any compressor on the market
