During their careers, most rotating machinery experts have dealt with the selection of advanced screw compressors. These are often chosen for their overall simplicity and efficiencies that generally exceed those of centrifugal compressors. Although control options can differ for dry-running vs. liquid injection-type screw compressors, volume control helps control the wide possible operating ranges of these machines. Controlling dry-screw compressors The following options can be used to control dry-screw compressors.1 Control by variable speed. Because screw compressors displace the medium positively, the most advantageous volume control strategy is to vary the speed. This may be done by u
