Compressor Description
The compressors used by the Model RTAA Series “R” Air-cooled chiller
consists of two distinct components: the motor and the rotors.
Compressor Motor
A two-pole, hermetic, squirrel-cage induction motor (3600 rpm) directly drives
the compressor rotors. The motor is cooled by suction refrigerant gas from
the evaporator, entering the end of the motor housing through the suction
line.
