AK-PC 783A

The AK-PC 783A is a comprehensive regulating unit designed for capacity control of compressors and condensers in refrigeration plants with a cascade function. This controller manages the high-pressure circuit, low-pressure circuit, and cascade circuit, ensuring optimal operation at energy-efficient pressure conditions. It includes oil management, simple heat recovery functions, and coordination between high-pressure and low-pressure controls. The AK-PC 783A is capable of providing signals to other controllers about operating conditions, such as forced closing of expansion valves and alarm messages.
