The technology used in the manufacture of a screw compressor has greatly evolved during the recent years which have significantly improved its level of performance. The simple yet efficient design makes it easy to operate and maintain at the same time offering flexibility during installation. It has lesser moving parts like valves or rolling bearings because of the new technology used. With this, the need for regular maintenance has been reduced and the life span of screw compressors becomes longer. The reliability rate also increase brought about by the lessening of moving parts. The vibration has been drastically reduced to 1/30th as compared to other compressors of similar type. This is because they are made to perfection to make sure there is no reciprocating motion. Lastly, due to the reduction of vibration level in the overall system, there is also a lowered risk of refrigerant loss, a relatively important aspect in operations.
