Danfoss EKE 347 Liquid Level Controllers
The EKE 347 is a dedicated controller for regulating refrigerant liquid level in industrial refrigeration: pump reservoirs, separators, intercoolers, economizers, condensers and liquid receivers.
A connected transmitter (Danfoss AKS 4100 / AKS 4100U guided-microwave level sensor) continuously measures the actual liquid level. By comparing it with the customer-entered setpoint, the controller regulates liquid flow in and out of the vessel with PI control.

Frequently asked questions
What is the Danfoss EKE 347?
The EKE 347 is a liquid level controller for industrial refrigeration. It reads the refrigerant level from a level sensor and drives a regulating valve to keep the level at setpoint — used on pump reservoirs, separators and receivers.
Which level sensors work with the EKE 347?
It is designed for the Danfoss AKS 4100 / AKS 4100U guided radar level sensors, giving accurate level measurement over a wide range.
Which valves can the EKE 347 control?
It controls ICM motorized valves via the ICAD actuator, and also works with AKV/AKVA pulse-width modulating valves.
How does the level control work?
You set the desired liquid level; the controller continuously compares the sensor signal with the setpoint and modulates the valve — opening to raise the level, closing to lower it.
Can the EKE 347 communicate with a PLC or BMS?
Yes — it has Modbus RTU (RS485) communication for integration with PLCs and supervisory systems, plus alarm relay outputs.
Where is the EKE 347 typically used?
Typical applications are low-pressure receivers, liquid separators and pump circulating vessels in ammonia and CO2 refrigeration plants.
Is this a genuine Danfoss product? How long is delivery?
Yes. We are an authorized Danfoss industrial refrigeration distributor in China, listed in Danfoss China’s official authorized dealer directory. All controllers are brand-new, genuine stock with valid warranty. We ship from China; express delivery takes about 1–2 weeks to most destinations worldwide.
Can you supply the complete level control package?
Yes — we regularly supply the sensor (AKS 4100), controller (EKE 347) and valve (ICM + ICAD) as a matched package. Tell us the vessel size and refrigerant for a complete quote.
