Abstract
A method of treating, tuning, assembling, and/or overhauling a twin rotor device () includes applying a coating material () on an internal set of working surfaces () of the twin rotor device when at least partially assembled. The coating may be factory or field applied to a new or used twin rotor device. The working surfaces may be uncoated or previously coated and may be built-up as the coating material forms a coating () on at least some of the working surfaces. Manufacturing variations of a pair of rotors () and a housing () may be compensated by the coating. One or more performance characteristics of the twin rotor device may be improved by the coating, and variation between a series of twin rotor device may be reduced or substantially eliminated. The coating may reduce internal leakage and increase volumetric efficiency of the twin rotor device. The twin rotor device may be a supercharger, a screw compressor, or other twin rotor device.
