Evaporator controls for a variety of refrigerants and operating ranges
Danfoss offers a range of evaporator controls with thermostatic expansion valves or with electric expansion valves. The valves can be used for a variety of refrigerants and operating ranges suited for food retail applications.
The evaporator controls with electric expansion valves are designed to ensure precise control of the injection of refrigerant liquid into the evaporators to ensure optimum performance and low energy consumption.
The evaporator controls from Danfoss have functions for regulating/monitoring temperature, defrosting, doors, rail heating, light and fan operation.
With remote communication as a part of ADAP-KOOL® refrigeration control system, evaporator controls comprise monitoring and control of display cases and cold rooms including alarm monitoring. The Danfoss electric expansion valves enable adaptive, automatic refrigeration control with no manual setting required. This provides additional energy savings.

Introducing the new AK-OB55 Modbus TCP/IP communication module
The new Modbus TCP/IP communication option board is compatible with the AK-CC55 Single Coil (UI) and Multi Coil, which have the capability to use the extension boards. This brings Ethernet-based structured cabling, new IP-based protocol, and potential for faster data polling – most noticeable in large store installations.
AK-CC55 series
Danfoss offers a solution that makes it easier than ever to save on adaptive and reliable food retail refrigeration. The new AK-CC55 case controls deliver energy savings of 6-10% compared to the next best alternative. It relies on acknowledged and advanced Danfoss adaptive super-heat algorithms to control refrigerated display cases and cold rooms.
The new ADAP-KOOL® Case Control generation ensures the system providing the same great value as always and now delivers a much better user experience, no matter if you’re an OEM, installer, service technician, or food retailer. For example, the large terminals on the AK-CC55 make it easy to loop the pressure transmitter cable from one controller to the next one.
Features and benefits
Significant energy savings with adaptive super-heat control algorithms and adaptive defrost.
Simplified installation and service with smartphone app and large terminals.
Suitable for any store size with Compact, Single Coil, and Multi Coil variants.
