The Electronic Expansion Valve Controller from Dotech Inc. is a dedicated control unit designed to regulate refrigerant flow by interpreting sensor inputs and adjusting valve position in real time. It is engineered for industrial HVAC and refrigeration applications where precise superheat management is critical. The controller accepts signals from temperature and pressure transducers, processes them via embedded algorithms, and outputs a modulated signal to drive the EEV actuator.
The unit is built for durability in high-vibration environments, with a conformal-coated circuit board and a die-cast aluminum housing. It supports multiple refrigerant profiles and adaptive learning modes to compensate for system aging. While the listing does not specify the microcontroller or firmware version, standard industry practice uses 16-bit or 32-bit processors with non-volatile memory for calibration retention.
This controller is purchased by system integrators in food processing, pharmaceutical cold chains, and commercial air conditioning manufacturers. It is typically shipped in anti-static ESD packaging, with 10 to 25 units per box. Trade terms are commonly FOB Ansan Port, with lead times of 5 to 8 weeks. Buyers must ensure the controller's communication protocol matches their existing BMS or PLC architecture before deployment.

Before placing an order, verify the controller's input/output signal compatibility with your existing sensors and valves. Confirm whether the firmware supports your refrigerant type and if calibration can be adjusted in the field. Request a sample unit to test response under simulated load conditions. Do not assume digital integration is possible without explicit protocol support.
Lead time is typically 5 to 8 weeks from Ansan Port. Confirm if the supplier offers FOB, CIF, or DDU terms. Payment is usually 30% advance, 70% against bill of lading. Ensure packaging includes anti-static bags and moisture absorbers. Request a serial number log per unit for warranty and traceability purposes.
Upon receipt, inspect for physical damage and verify that the power supply matches the unit's rating. Use a multimeter to test output voltage under load. Confirm that the calibration settings match your system's refrigerant and operating range. Request a Certificate of Calibration with test points and tolerance limits, even if not certified, to validate performance.
