CircuitSolver® Thermostatic Balancing Valves for Cold Water Recirculation Systems On Therm-Omega-Tech, Inc.

To balance a cold water recirculation system, a CircuitSolver® Union Cold Water thermostatic valve is installed at the end of each branch or riser. The valve automatically monitors and modulates flow based on current water temperatures to maintain a set temperature in the system to mitigate Legionella growth.

The CircuitSolver® Union Cold Water balancing valve uses the same reliable and precise thermal actuator technology as the traditional CircuitSolver® for hot water balancing. Designed with ease in mind, the CSU-CW is offered in sizes ranging 1/2" to 1" and is available in a range of configurations to suit individual system needs.
