CircuitSolver’s Cold Water Balancing Valve is designed to automatically balance cold water recirculation systems, effectively mitigating the risk of Legionella bacteria growth in a domestic cold-water system by continuously monitoring water temperatures and modulating flow to maintain a set temperature at the end of each branch or riser. This automatic response to water temperature balances the cold water throughout the system, reduces stagnation, and ensures “residual chlorine” is distributed throughout the system, the company says.
