Model RTCW eliminates oil and oil-bearing parts, providing less vibration and sound levels as low as 77 dBA. The digitally controlled magnetic bearing system, consisting of both permanent magnets and electromagnets, replaces conventional lubricated bearings. The frictionless compressor shaft is the compressor's only moving component. The design includes two independent centrifugal compressor circuits and shell-and-tube evaporator and condenser components that range in size from 120- to 190-ton capacity. The system is 35" wide, uses R-134a refrigerant and has a touch-screen controller.
