Sanhua presents eDual (SECD04)

Sanhua launches eDual (SECD04) , an advanced controller for managing up to 2 electronic expansion valves, designed to optimize performance and efficiency in HVAC&R systems.

The Sanhua SECD04 series driver features a superheat control algorithm capable of managing two independent expansion valves in the same circuit. The control logic implemented in the eDual Driver ensures precise automatic superheat regulation, maximizing evaporator efficiency. With its compact design, intuitive interface, and robust features, the SECD04 represents a major step forward in intelligent thermal management, offering precise control and advanced compatibility.

Main features of the eDual Driver (SECD04):

• Control of two EEV stepper valves
• Advanced PID algorithm for automatic and precise superheat regulation
• Quick-Safe protection that ensures acceptable system overheating protection with defined and non-exceedable upper and lower limits; a function that ensures correct system operation under any conditions
• Small size, optimized design for DIN rail mounting, easy to install
• High energy efficiency, ensures maximum evaporator efficiency
