AK-CC 750 controllers are complete regulating units which together with valves and sensors constitute complete evaporator controls for refrigeration appliances and freezing rooms within commercial refrigeration.
Generally speaking they replace all other automatic controls containing, inter alia, day and night thermostats, defrost, fan control, rail heat control, alarm functions, light control, thermo valve control, solenoid valve, etc.
The controller is equipped with data communication and is operated via a PC.
In addition to evaporator control the controller can give signals to other controllers about the operating condition, e.g. forced closing of expansion valves, alarm signals and alarm messages.
Advantages:
- Control of 1 to 4 evaporator sections.
- Adaptive superheat control ensures optimum evaporator usage in all operational circumstances.
- Electronic injection with AKV valve.
- Traditional temperature regulation using on/off or modulating control of solenoid valve for both DX and indirect brine system.
- Weighted thermostat and alarm thermostat.
- Defrost on demand based on evaporator capacity.
- Appliance cleaning function.
- Light control using door switch or network signal depending on day/night operation
- Rail heat pulsing depending on day/night operation or dew point.
- Monitoring of door alarm and control of light/refrigeration depending on location of door switch.
- Log function for registration of historical parameter values and alarm modes.
