AK-PC 772A is complete regulating units for capacity control of compressors and gas cooler in a small CO2 refrigeration systems.
Either as a compressor and condenser control on MT or as a booster system. There can be regulated with one parallel compressor.
The controller is with oil management, heat recovery function and CO2 gas pressure control.
In addition to capacity control the controllers can give signals to other controllers about the operating condition, e.g. forced closing of expansion valves, alarm signals and alarm messages.
The controller’s main function is to control compressors and gas cooler so that operation all the time takes place at the energy optimum pressure conditions. Both suction pressure and gas pressure are controlled by signals from pressure transmitters and temperature sensors.
