The main part of a screw compressor is a pair of meshing rotors with helical grooves machined in them contained in a casing, which fits tightly around them. Minimal clearances separate the rotors and casing. The rotors mesh like gears in such a manner that as they rotate, the space formed between them and the casing is reduced progressively. Thus any gas trapped in this space is compressed. Increasing the operational efficiency and complexity of the machining process of these rotors have always been one of the significant challenges of screw compressors. The primary source of the decrease in thermodynamic efficiency is the internal leakage caused by the presence of clearance between the two rotors. In this company, it is possible to achieve optimum efficiency by carefully designing the rotor geometrical profile. It is also possible to produce these parts with very high precision using advanced machining machines.
