Evaporator control

The EKE 400 Evaporator Controller is specifically designed for industrial refrigeration systems, significantly reducing installation time and costs. The EKE 400 can be used for defrosting both DX and flooded evaporators and supports multiple defrost methods, including hot gas defrost (pressure control/liquid drain), electrical defrost, and water/brine defrost.

The easy-to-use wizard enables quick setup of key parameters and proper valve selection for specific applications. As the wizard guides users, it filters out irrelevant parameters based on current selections and common selections used previously. The controller includes both modbus communication, which allows integration to our PLC systems, and CAN bus, which manages internal communication between EKE 400 controllers.

Optimize your system's cooling mode and defrost sequence for efficient, safe, and trouble-free evaporator operation.
