AK-CC55 Case Controllers

The AK-CC55 Case Controllers series is a versatile line of refrigeration case and cold-room controllers built for equipment that uses electronic expansion valves (EEVs). Available in Compact, Single Coil, Single Coil UI, and Multi Coil versions, the range scales from straightforward installations to systems requiring coordinated control of multiple evaporator circuits. Each controller accepts a pressure input, several temperature probes, digital inputs, an analog output, and relay outputs, consolidating regulation and monitoring on a single platform. Control is primarily based on temperature readings taken along the evaporator airflow path, with additional sensors assignable for product-temperature tracking, evaporator temperature measurement, and defrost management. Across the lineup, listed variants include features such as MODBUS communication, optional LON connectivity on selected models, CO2-compliant capability, and support for AKV or TXV/AKV-based control strategies, depending on the specific controller version.
