Dual electronic expansion valve controller
2nd September 2025
SPAIN: Sanhua has introduced eDual (SECD04), a superheat controller that can handle two independent expansion valves in the same circuit.
The eDual is said to ensure accurate automatic adjustment of superheat, achieving the most efficient use of evaporators.
With its compact design, intuitive interface, and robust functionality, the SECD04 is described as a significant step forward in intelligent thermal management, offering precise control and enhanced compatibility.
Its advanced PID algorithm is said to ensure accurate automatic adjustment of superheat, while Quick-Safe prevention of low and high superheat ensures the system operates well at any conditions.
The SECD04 is suitable for use with the majority of refrigerants on the market, including HFCs, HFOs, and HFC/HFO blends as well as “natural” refrigerants.
Operating temperature is from -30°C to around 55°C.
