Controllers and drivers for stepper motor valves

Superheat controllers are used to regulate evaporator superheat and control stepper motor valves with high precision. They help optimize evaporator charge, support stable operation, and improve system efficiency by regulating superheat to the lowest possible level within a short period of time. In cold room applications, superheat controllers are part of the wider control layer of the refrigeration system and are included in the cold room portfolio. Beyond cold rooms, these controllers are also used in air conditioning, commercial refrigeration, food retail, chillers, heat pumps, transport cooling, and other refrigeration and HVAC applications.

Product types shown: 7

EIM 336
The EIM 336 is a superheat controller that can be used to control the opening degree of a valve based on the superheat of the evaporator. This is applicable in applications such as air conditioning, heat pumps and refrigeration.
An alternative option is to use the controller in manual mode via modbus communication and use it as a valve driver by setting the valve opening degree manually.
EKE 100
The flexible pre-programmed EKE 100 superheat controller and stepper valve driver from Danfoss provides ultimate software control, allowing you to tailor the performance of your system to your exact requirements. EKE 100 is ideal for controlling a wide range of air conditioning, commercial and industrial heat pumps, commercial refrigeration and food retail applications, such control helps you to achieve the highest efficiency in the system. EKE 100 is generally used where there is a requirement for accurate control of superheat or as stepper valve driver. The superheat is regulated to the lowest possible value within a short period of time. It 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 100 1VK
The SH controller kit is a comprehensive equipment package designed for controlling ETS 5M electronic expansion valves across various applications, including air conditioning, commercial refrigeration, and food retail.

It is ideal for situations requiring precise superheat control, effectively regulating superheat to the lowest possible level in a short time frame. By optimally managing the evaporator's superheat, even amidst significant load variations, the SCK helps reduce energy consumption and operational costs.
EKE 1A,B,C (PV05), 1D (PV02)
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. It 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 2U
EKE 315
EKE 315 Superheat Controller can operate both Puls Width Modulated Valves and Motorized valves. A Remote display can be connected. Data communication via ModBus RTU, RS485 is included.
EKF 1A / EKF 2A
Stepper Valve Driver EKF series is for use where stepper valves must be accurately controlled typically in commercial air conditioning, heat pumps, commercial refrigeration and food retail applications.
