Superheat controller EC3-X33 with built-in backup battery and display unit ECD-002

The new electronic superheat controllers EC3-X33 control the superheat at the evaporator. A complete system consisting of electric control valve, superheat controller, temperature and pressure sensor controls the superheat exactly to set point, independent from condensing pressure. The MOP function protects the compressor from dangerous overload conditions. The positive shut-off function eliminates the use of an additional solenoid valve, because the built-in backup battery closes the valve after power is lost. The controller can be easily adjusted for each refrigerant and valve type.
