CircuitSolver, a ThermOmegaTech brand, announced its CircuitSolver Cold Water Balancing Valve (CSU-CW). The CSU-CW is a dynamic valve designed to automatically balance cold water recirculation systems utilizing the same reliable and precise thermal actuator technology as the original CircuitSolver for balancing recirculating hot water systems, the company says. The valve will effectively mitigate the risk of Legionella bacteria growth in a domestic cold-water system (DCWS) by continuously monitoring water temperatures and modulating flow to maintain a set temperature at the end of each branch or riser, the company adds.
