Ranco Digital Pressure Based Rack Controller for Suction and Discharge Control Pressure

Pressure controller for refrigeration systems designed to control suction (compressors) and discharge (fans) pressures. It is possible to connect 4 pressure transducers and 6 temperature sensors for up to 2 independent refrigeration groups (2 suctions and 2 discharges). It offers a number of control modes through 26 digital outputs, 4 analog outputs and 5 digital inputs. The last 4 digital outputs can be set for alarm triggered by temperature, pressure or through the digital inputs, which can also be associated to night setpoint mode. Using a customizable gas curve in addition to pressure and temperature readings, the PCT-3001 plus is capable to measure the sub-cooling and overheating of the refrigeration system. The kill zone feature enhance energy savings while optimizing compressor running time.
