Screw compressors, also known as twin-screw compressors, are positive displacement machines widely used in industrial refrigeration, air compression, gas processing, and oil & gas applications. Unlike reciprocating compressors, they offer high reliability, oil-free or oil-injected operation, and smooth, pulse-free flow. also known as twin-screw compressors
Between the rotor tips and the housing casing. they offer high reliability
