EKE-1A Danfoss expansion valve driver

EKE-1A Danfoss expansion valve driver

The flexible pre-programmed EKE superheat controller from Danfoss provides ultimate software control, allowing you to tailor the performance of your system to your exact requirements. EKE is ideal for controlling a wide range of commercial air conditioning and refrigeration applications, such control helps you to achieve the highest efficiency in the system reducing the operational cost by up to 20% with minimal effort. EKE is generally used where there is a requirement for accurate control of superheat or temperature control in connection with air conditioning and refrigeration. The superheat is regulated to the lowest possible value within a short period of time. EKE regulates the superheat of the evaporator by charging optimally even when there are great variations of load resulting in reduction of energy consumption and operational cost. EKE superheat controller can be used in HVAC and refrigeration applications such as Chillers, Processing plant / Cabinet cooling, Cold store (air coolers), A/C plant / Air conditioning, Heat pumps. Residential Heat Pump, Transport cooling, Stepper Motor Driver and etc.

EKE 1A is the best choice to control the refrigerant flow and adjust the superheat in refrigeration and air conditioning systems. The superheat is regulated to the lowest possible value within a short period of time by EKE 1A, the flexible pre-programmed superheat controller from Danfoss. It regulates the superheat of the evaporator by measuring suction pressure and temperature. EKE 1A has CAN-RJ port to connect with MMIGRS2 danfoss display and gateway port for MMIMYK device.

EKE 1A Applications

EKE 1A is used in three main applications :

• Driver mode

A master controller is commanding the valve open degree to the EKE 1A controller. The control signal can be fed by Analog signal 0 – 10 V, a 4 – 20 mA or Bus communication via RS485 (Modbus RTU).

• Superheat control mode

EKE 1A can use as a PI controller that controls the superheat of the evaporator based on a suction pressure and temperature sensors. In superheat mode the controller will control the superheat to be stable and close to the superheat setting. If superheat is too low the flow in the expansion is decreased and superheat will be higher.
