Rotor Design Solutions offer rotor profiles and tooling for screw compressors used in the Air and Refrigeration sectors. Customers may choose from established Industry proven compressor profiles or more modern options that are easier to manufacture.
Advanced rotor profiles are required for a screw compressor to be efficient. By carefully controlling the geometry of the profile, the leakage between the rotors and also the leakage through the ‘blow hole’, a leakage path between the rotors and the housing, may be minimized. At the same time as controlling the leakage, it is also important to maximize the displacement, to give as much flow through the compressor as possible. It is also important that the rotors do not have a profile with sharp corners or steep sides that are difficult to manufacture.
It is difficult to design profiles that exhibit all the characteristics detailed above. Often, if you optimize the profiles to one of these features, it is detrimental to the others. At Rotor Design Solutions we have many years of experience, not just in the design of the rotors, but also in their manufacture. This enables us to provide design solutions with the optimal balance between production and performance.
Profiles and tooling may be purchased as individual items, or as custom software options with the ability to generate profile and tooling for a range of rotor size and operating speeds.
