Evaporator controller for industrial and heavy commercial refrigeration

Industrial refrigeration control easier than ever before

The new EKE 400 is specifically designed to control industrial refrigeration evaporators – in small as well as large systems.
Following the Distributed Control System (DCS) architecture, advanced control algorithms, and wizard for quick set-up and commissioning EKE 400 significantly reduces controls installation time and costs and provides operational safety and efficiency.

The EKE 400 evaporator controller manages the complete operation in cooling and defrost mode for optimal operation and defrost sequence (Ammonia, CO₂, and HFC/HCFC based systems). It’s applicable for defrosting both flooded evaporators and DX evaporators* and supports multiple defrost methods, including hot gas defrost (pressure control/liquid drain), electrical defrost, and water/brine defrost.

An Easy-to-use Wizard enables quick set-up of key parameters and efficient commissioning, and the predefined process sequence ensures reliable operation and defrost. The EKE 400 is especially designed to get the best performance from Danfoss valves, however, it also works with non-Danfoss valves.

EKE 400 includes MODBUS communication which allows integration to central PLC system. However, it can also be used without central PLC as standalone.
