The semi-hermetic, compact, helical twin-screw cooling compressors provide stepless, proportional control of the cooling capacity. The three-phase, two-pole motor is suction gas-cooled and features a no-load start mechanism. The units have at least two compressors, each with an independent cooling circuit.
