AK-PC 781

AK-PC 781 EKC is a complete control unit for capacity regulation of compressors or condensers in small cooling systems.
AK-PC 781 includes features that also makes it particularly suited to cascade systems e.g. control of the compressor’s capacity for separate control pressures in low-pressure circuits.
In addition to capacity control the regulator can give signals to other regulators of operating conditions, e.g. forced closure of expansion valves, alarm signals and alarm messages.
The regulator’s primary function is to control compressors and condensors so that the operation always operates takes place energy-optimal pressure conditions. Both suction pressure and condensation pressure are controlled by signals from pressure sensor.
