Owing to the specific design this type of compressor does not require any working valves. Motor cooling is achieved by the returning cold refrigerant vapour which mainly flows through the bores in the motor rotor.Bitzer COMMAC SERIES :Bitzer 26/3/08 10:58 PM Page 4 BITZER CSH Screw Compressor design features BITZER Compact Screws are of two-shaft rotary displacement design with newly developed profile geometry. The compressor is driven by a three-phase asynchronous motor which is built into the compressor housing. To protect against reverse running when the compressor is switched off (expansion operation) a check valve is incorporated in the discharge chamber. fitted into an enclosed housing precisely located at both ends in roller contact bearings (radial and axial).
