Screw Compressor

Two-stage compression From Petrotek UAE
The main difference between two-stage and single-stage compression is that the compression process at the two-staged compression is splitted on two airends. After compression in the first airend, the air is intercooled. Then the air in the second compressor airend is compressed to the final pressure.

The compression process is close to isothermal compression, i.e. the outlet temperature is almost as high as the inlet temperature, thus avoiding energy losses.

With two-stage compression, the pressure differences in the individual stages are smaller. This reduces leakage losses.

Overall, two-stage compressors consume between 11 and 15% less energy than single-stage compressors of comparable size. Screw Compressors in uae
