The variable speed VZH compressors can improve efficiency by more than 30 percent compared to fixed-speed compressors. The inverter scroll compressor range includes cooling capacities between 4 and 6.5TR with a single compressor, and up to 13 tons with a manifold configuration. With a permanent magnet motor and intermediate discharge valves, which can help improve part-load efficiency by up to 24 percent, the compressor range facilitates efficiency ratings up to 21 IEER and can modulate from 15 to 100 RPS.
