The R Series(tm) central chillers employ rotational compression technology with up to 50% fewer moving parts than reciprocating compressors to provide reliability, performance and economy in the 30 to 195-ton range of cooling capacities. In sizes from 30 to 100 ton capacity, R Series central chillers use hermetically sealed scroll compressors; semi-hermetically sealed screw compressors are used in systems sized from 54 to 195 tons. Up to 100 tons, both styles of compressors are matched to brazed plate evaporators; from 115 to 195 tons they match to shell and tube evaporators. Two levels of network capable PLC controls are offered.
