Danfoss EKE 400 Evaporator Controllers

Danfoss Authorized Distributor (China) Wenzhou Phonetoo is an authorized Danfoss distributor in China — listed in the official Danfoss dealer directory.

The Danfoss EKE 400 is a dedicated controller for evaporators in industrial refrigeration, managing the complete operation in cooling and defrost mode: refrigerant injection, air/media temperature, defrost, fans — everything needed to run an evaporator safely and efficiently.

Its sibling, the EKE 450, adds Danfoss NeoCharge® control for low-charge ammonia and CO2 systems (CCR pump circulation and WDX wet direct expansion) — ask us about the NeoCharge solution.
