Sanhua has introduced the eDual (SECD04), a dual electronic expansion valve controller designed to improve the performance and energy efficiency of HVAC&R systems. The new controller manages two independent expansion valves in a single circuit and offers precise automatic superheat control.
The SECD04 features an advanced PID algorithm to ensure accurate adjustment of superheat and includes Quick-Safe functionality to prevent low or high superheat levels, helping to maintain stable system operation under varying conditions.
The controller is compact, supports rail mounting for easier installation, and is designed to maximize evaporator efficiency.
Sanhua describes the SECD04 as a step forward in intelligent thermal management due to its combination of compact design, intuitive interface, and enhanced compatibility.
