45kW 2 stage rotary screw air compressor

In a V&T twin screw air compressor, the elevated temperature air resulting from the initial compression phase is cooled via oil at a constant pressure before it proceeds to the subsequent compression stage. This cooling process closely mimics isothermal compression, minimizing potential energy loss. The pressure ratio for each compression phase is reduced, leading to a significant decrease in leakage at the rotor seals. Compared to single-stage compression, this design can boost the theoretical air delivery volume by 8 to 15%, with a corresponding reduction in energy consumption within the same percentage range. The cost-effectiveness of such compressors is optimized during prolonged periods of full-load operation. With this two-stage approach, components experience less stress per stage and operate under lower thermal loads, which contributes to extended service longevity.

air compressor 2 stage is suitable for applications that require high-quality compressed air, high compression ratio, and energy efficiency. For example, in large air compression systems, industrial automation, textiles, pharmaceuticals, food, etc., two-stage screw air compressors can meet the demand for efficient and stable air supply. In addition, in some cases where noise and vibration requirements are high, two-stage screw air compressors also show better performance.
