RS Series employ rotational compression technology with up to 50 percent fewer moving parts than reciprocating compressors. In sizes from 60 to 195 ton capacity, the central chillers utilize semihermetically sealed screw compressors. Up to 100 tons, compressors are matched to brazed plate evaporators; from 115 to 195 tons, they match to shell-and-tube evaporators. The screw compressors use R-134a, a non-CFC refrigerant providing energy efficiency increases of up to 12 percent.
