With straightforward installation, intuitive wizard, and built-in design flexibility the Danfoss EKE 400, is said to provide the tools needed for optimal cooling mode and defrost sequence for efficient, safe, and trouble-free evaporator operation.

The EKE 400 1.1 comes with new features such as support for DX evaporators, with or without hot gas defrost, including CO2 and a new cooling mode enabling DX direct expansion control.

It is specifically designed for industrial and heavy commercial refrigeration systems. Based on a trusted distributed control system, advanced control algorithms, and wizard for quick set-up and commissioning, the EKE 400 is said to significantly reduce installation time and costs as well as providing operational safety and efficiency.
