EVD Evolution Twin


EVD Evolution Twin is a controller comprising two drivers for two-pole stepper motors that can independently manage two electronic expansion valves. The device is designed for DIN rail mounting and comes with plug-in screw terminals. Each driver can control refrigerant superheat and optimise refrigerant circuit performance, and at the same time guarantee maximum system flexibility, being compatible with various types of refrigerants and valves, in applications that use chillers, air-conditioners and refrigeration units, including subcritical and transcritical CO2 systems.
