New Generation of Electronic Expansion Valve Controller
With the state-of-the-art technologies, EVC20 has many smart functions and features which can be applied to various fields.

High Performance and Stability
A top-level performance and stability can be achieved with high speed CPU, biopolar step motor driver, 2 RS485 communication ports, and extra remote displays

Precise PID and Superheat ControlBased on the advanced PID algorithm, precise superheat control is possible.

Intelligent Temperature and Pressure Control(Hot Gas Bypass and Liquid Injection)Temperature and pressure are controlled intelligently by hot gas bypass and liquid injection.

Compatible with Various Refrigerants
R22, R134a, R404a, R407c, R410a, R717, and R23 are compatible and more refrigerants will be available soon.

RS485 Communication
EVC20 can monitor and control up to 128 units(PC, heat pumpt controller, DDC, and etc.) via RS485 communication. 2 extra displays(cable length: 5m) can be connected as well.

Manual Valve Open Ratio Configuration
Operators can configure the valve open ratio manually for the special purpose temporarily.

Smart-Rail Mount

Perfect Tech Support
EVC20 was developed 100% by Dotech's unique design and advanced technologies and tech support is provided perfectly.
