Frictionless chiller

March 6, 2006




Sterling says its RTCW frictionless chiller offers a savings of 35% over rotary screw designs. A 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 features two independent centrifugal compressor circuits and shell-and-tube evaporator and condenser components that range in size from 120 to 190 ton capacity. The elimination of oil and oil-bearing parts increases energy efficiency and reduces noise levels, says the company.
