New Danfoss Controller AK-CC25 Pro – Advanced Control for Refrigerated Display Cases and Cold Rooms
Danfoss introduces a new generation of refrigeration controllers – AK-CC25 Pro and AK-CC25 Pro BT. These modern controllers are designed for refrigerated display cases and cold rooms with integrated or remote compressors. The solution is engineered for high flexibility, fast commissioning, and reliable, energy-efficient operation in MT and LT applications.
One Platform – Wide Application Coverage
AK-CC25 Pro supports 9 application modes, covering a broad range of refrigeration systems – from standard single-circuit solutions to advanced configurations with two compressors or dual refrigeration circuits. A key feature is the fully flexible application mode, allowing the user to freely define all inputs and outputs. This makes the controller suitable for virtually any refrigeration application.
The controller is suitable for:
- refrigerated and frozen display cases
- cold rooms and freezer rooms
- systems with ON/OFF or variable speed compressors
- remote cabinets with a liquid line solenoid valve.
Intuitive User Interface and Secure Operation
The front panel features a large, backlit display with clearly visible digits and capacitive touch buttons, enabling fast and intuitive access to core functions such as temperature adjustment, defrost activation, lighting control, and alarm overview.
A built-in multi-level access system (L0–L3) ensures clear separation between user, service, and commissioning access rights. The access concept complies with the requirements of RED 2014/53/EU, providing effective protection against unauthorized access and configuration changes.
Bluetooth and Modbus – Ready for Digitalization
The AK-CC25 Pro BT variant includes Bluetooth Low Energy, enabling direct connection to smartphones and tablets. Using the AK-CC Connect mobile app (Android and iOS), users can:
- perform quick initial setup and commissioning
- adjust parameters and optimize operation
- monitor operating status and alarms
- carry out local service without physical access to the controller.
In addition to wireless connectivity, all AK-CC25 Pro controllers feature integrated Modbus RS-485 communication, allowing easy integration into supervisory systems (e.g. Danfoss System Manager) or third-party control and SCADA solutions. This enables centralized monitoring and coordinated operation of multiple controllers.
Advanced Functions for Reliable Refrigeration
AK-CC25 Pro combines a comprehensive set of advanced functions to enhance system reliability, energy efficiency, and operational safety:
- precise temperature control using multiple sensors (air, evaporator, product)
- multiple defrost methods (natural, electric, hot gas, pulsed electric)
- condenser temperature monitoring and compressor safety chain supervision
- coordinated defrost across multiple display cases
- night/ECO operation mode
- door, lighting, and heater control
- HACCP support via a dedicated case cleaning function.
Compact Design and Easy Installation
The controller is designed for panel mounting and features IP65 front protection, ensuring reliable operation in demanding environments. A wide power supply range (100–240 V AC) combined with an integrated switch-mode power supply allows the same controller variant to be used globally.
Conclusion
AK-CC25 Pro and AK-CC25 Pro BT represent a modern, flexible, and digitally ready solution for refrigeration control. By combining advanced control functionality, an intuitive user interface, and connectivity via mobile applications and supervisory systems, they are an ideal choice for refrigeration equipment manufacturers, installers, and operators seeking a reliable and future-proof controller for commercial refrigeration systems.
