Two-Stage Semi-Hermetic
Two-Stage Semi-Hermetic Compressors

Emerson’s 6T series two-stage semi-hermetic compressors are available from 15–30 HP. These compressors are designed for operation in plants requiring extremely low evaporation temperatures using R-22 or R-404A / R-507 refrigerants. The distinctive advantage of operating two-stage compressors allows evaporation temperatures to go as low as -60°C.  Liquid sub-cooling operation by means of a plate heat exchanger is possible in order to improve cooling capacity and overall energy efficiency of the system.
