Compressor
The helical-rotary chiller uses 2 screw-like rotors to perform the compression
process.
The rotors are meshed and fit, with very close tolerances, within a housing.
Only the male rotor is driven by the compressor motor. The lobes of the male
rotor engage and drive the female rotor, causing the 2 parts to counter-rotate.
