EKE 80

The EKE 80 controller can drive a number of High Pressure (HP) or Low Pressure (LP) Industrial Large Ejectors (ILE), Multi-ejectors (ME), and ICAD B actuators that operates the Danfoss ICMTS motor operated valve, in order to facilitate lifting of the Medium Temperature (MT) suction flow to offload the MT compressor thereby decreasing the overall energy consumption of a cooling system.
It is compatible with the Danfoss AK-PC 782A, AK-PC 782B, and is Modbus RTU interoperable with PLCs. The EKE 80 driver is able to integrate into existing cooling solutions with minimal effort both in terms of physical working conditions and regulatory compliance.
The EKE 80 driver requires 2 input signals (1 x DI enabling signal and 1 x AI capacity reference signal) from the main controller/PLC. It will then be responsible for providing the appropriate output signals to the ejectors and valve-actuators.
The EKE 80 is also responsible for driving its expansion module when more than 4 ejectors require driving. The EKE 80 and the EKE 80 expansion module are able to support the use of:

• up to 8 Industrial Large Ejectors, or 7 Industrial Large Ejectors and 1 Multi-ejectors, and
• 2 ICAD B units that operate Danfoss ICMTS
• Modbus communication
