Data Sheet
Case/room controller (EEV) Type AK-CC55
For flexible control of refrigeration appliances and cold storage rooms.
AK-CC55 is a complete refrigeration appliance control with great flexibility to adapt to refrigeration appliances and cold storage rooms.
AK-CC55 Compact, Single Coil, and Multi Coil controllers are optimized to control refrigerated display cases or cold rooms with electronic expansion valve type AKV. In addition to the valve output, the controllers hold a pressure input, temperature sensor inputs, digital inputs as well as an analogue output and relay outputs that can be applied to numerous functionalities in a refrigeration system.
The temperature in the appliance is registered by temperature sensors in the air flow before the evaporator and after the evaporator. A setting for thermostat, alarm thermostat and display reading determines the influence the sensor values should have for the control functions. Additional sensors can be used for registration and alarming of the temperature near the food items, registration of the temperature of the evaporator and also as defrosting sensors.
