Emerson™ CO2 high pressure controller An integral part of Emerson’s transcritical control system The Emerson CO2 high pressure controller manages the high pressure and flash gas bypass valves directly based on the pressure/temperature at the gas cooler outlet as well as the pressure of the receiver. Features • Manages subcritical and transcritical mode of operation based on temperature input • Local display (optional) • High pressure valve control to insure optimum efficiency during transcritical operation • Communication with E2 supervisory system to allow users to manage and monitor all aspects of the high pressure controller. • Helps maintain optimum pressure receiver • Remote monitoring capabilities • Safety modes coordinate high pressure and bypass valves based on receiver pressure • Compatible with Emerson’s CX valve • Optional heat reclaim mode • Fallback mode in case of sensor/transducer failure Commander HSK inverter drive High pressure controller Gas cooler/condenser HP valve (CX valve) Commander HSK inverter drive Bypass valve (CX/EX valve) MT compressors Flash tank Copeland 4MTLS E2 controller XM case controller MT expansion valve (EX EEV) MT evaporator Copeland Scroll Digital ZO Copeland Scroll ZO LT compressors LT expansion valve (EX EEV) LT evaporator XM case controller Sensor and probe support Dimensions Standard temp sensors (i.e. P/N 501-1121) Pressure transducers: 1000 psi (P/N 800-2710) or 2000 psi (P/N 800-2720) depending on application General specifications 24 VAC input power RS485 communication to E2 supervisory system 2013RS-58 (11/13) Emerson is a trademark of Emerson Electric Co. ©2013 Emerson Climate Technologies, Inc.
