Abstract

A compressor plant comprising two or more compressor stages. Each stage (11) comprises a driving motor (19) having variable rotary speed. Pressure sensing means (82) is provided for each stage. The speed of the compressor stage is controlled so that the pressure at the outlet (92) is kept within desired limits. Pressure gas take-off means (51) of variable capacity is provided at the outlet of each compressor stage.
