Danfoss AK-CC 750A evaporator controller
Danfoss AK-CC 750A controller from the ADAP-KOOL range for refrigerated display cases and cold rooms. It controls 1 to 4 evaporators with AKV or stepper motor electronic expansion valves, and handles the thermostat, defrosts, fans, lights and alarms. Danfoss ref. 080Z0140.
The AK-CC 750A is a complete evaporator controller for refrigerated display cases and chilled or frozen cold rooms. Together with its valves and sensors, it replaces the day/night thermostats and the control of defrosts, fans, rail heat, lights and alarms. It controls up to 4 evaporator sections, each with its own electronic expansion valve, and grows with extension modules as the system grows.
Key benefits
- 1 to 4 evaporators with a single controller, for a display case or a cold room with several evaporators.
- Adaptive superheat: electronic injection with an AKV valve, or with an ETS or CCMT stepper motor valve using the AK-XM 208C module. The evaporator stays well filled in all operating conditions.
- Adaptive defrost: the controller uses the valve opening to follow ice build-up. It cancels unnecessary defrosts and starts one on its own when the evaporator begins to block.
- Thermostat: day/night, weighted and alarm thermostat; on/off or modulating solenoid valve, for direct expansion as well as brine systems.
- Case functions: cleaning, lights from the door switch or the network, rail heat pulsing by day/night or dew point, door alarm.
- Log of measurements and alarms, exportable to Excel or AKM software.
Specifications
- Supply 24 V AC or DC ±20%, 8 VA; one class II transformer per controller.
- 11 analogue inputs: Pt1000 sensors or PTC1000, AKS 32R, AKS 2050 or AKS 32 (1–5 V) pressure transmitters, 0–10 V signals and contacts.
- 8 outputs: 4 solid state outputs (AKV valves, fans, rail heat) and 4 relays.
- Up to 11 AK-XM extension modules for more inputs, relays or stepper valve outputs.
- LON communication to the ADAP-KOOL network and an AK-SM 800A system manager; PC setup with AK-ST 500 software (USB port).
- Up to 4 EKA 163B or EKA 164B displays for temperatures (with a 2 m cable or a 6 m cable), or the MMIGRS2 graphic display.
- DIN rail or wall mounting, IP10 (to be fitted in an electrical panel), ambient temperature −20 to 55 °C, 0 to 95% RH non-condensing.
