Description
Carel electronic expansion valves with stepper motor. Controlled by a controller/driver, as well as a temperature and a pressure sensor. EVD evo driver/regulator can be equipped with a removable display with which configuration and settings can be made. At start-up, a number of questions are asked about valve type, refrigerant, pressure sensor value and the type of unit to be controlled. Then the basic configuration is ready. The driver/expansion valve combination can also be used for capacity control, liquid injection or hot gas injection. In this case, the driver is controlled by an external 0-10 V signal.
