call- [EVC10B] Electronic Expansion Valve Controller for Unipolar Step Motor
- - The most advanced algorithm of precise adaptive PID control over superheat
- Various valve open control modes:
External signal input(4-20mA, 1-5V)
RS485 communication
User setup
- Quick-Safe to ensure prevention of low and high superheats and protect the system under any conditions
- Hot gas bypass operation for precise control
- Compatible with various refrigerants(R22, R134a, R404a, R407c, R410a, R717, R23)
- Smart-rail mount design
- Perfect tech support by a developer(DOTECH)
EVC10B was developed 100% by Dotech's own creative ideas and technologies.
