CircuitSolver® Union Sanitary Flush Solves Bacteriological Problems

Q&A with ThermOmegaTech® about new automatic DHWS balancing valve – CircuitSolver® Union Sanitary Flush

Being “first” often sets the bar high. As one of the first manufacturers of a thermostatic balancing valve for domestic hot water systems, The ThermOmegaTech® commitment has not just been to set the bar but also to raise the bar. Since the introduction of its CircuitSolver® in 2012, the company has frequently added components, including ball valves, strainers, check valves and ProPress ends to meet customer demand.

In April 2018, the innovation continued with the launch of the CircuitSolver® Union Sanitary Flush thermostatic balancing valve for domestic hot water systems. The union is integral with the valve body, which also has an optional integral check valve. A key feature of the CircuitSolver® Union Sanitary Flush is the new capability to automatically balance a domestic hot water system during a high-temperature sanitary flush procedure.

In the following Q&A with ThermOmegaTech®, Plumbing Engineer explores the features of the new product, including its ability to mitigate Legionella and other bacteriological problems.

PE: What makes CircuitSolver® Union Sanitary Flush different from other valves on the market?

TOT: It has all-stainless steel construction for maximum corrosion resistance and durability. It is NSF61 and NSF372 certified — even though it seems that all components in a domestic hot water system (DHWS) should be certified and most plumbing codes and specifications say they must be, not all balancing valves are certified. The valve is completely automatic, thermostatically balancing both the standard recirculation temperature as well as the high-temperature sanitary flush cycle. No power, signal, or powered actuators are required, as in some other such balancing valves.

ThermOmegaTech® design is highly resistant to mineral buildup and the adverse effects of debris in the piping system. It is the only tamper-proof thermostatic balancing valve on the market. Other competitive devices are adjustable for several reasons: those manufacturers don’t manufacture their own thermal actuators as ThermOmegaTech® does. They aren’t as flexible and offer all the setpoint variations we can, so their valve is adjustable, making it prone to tampering and/or being set to a temperature other than what the designer specified.

With this valve, the plumbing system designer specifies the desired temperature and the valves are factory-set to that exact setting.

PE: What are the benefits or special features of the CircuitSolver® Union Sanitary Flush that are specific to those designing and specifying thermostatic balancing valves for DHWS?

TOT: CircuitSolver® Union Sanitary Flush brings the benefits of the standard CircuitSolver® into high-temperature sanitary flush applications. There is no manual balancing required. It can simply be installed; once the system is turned on, within minutes the building’s DHWS is balanced. Unlike manual balancing valves or fixed-flow devices, CircuitSolver® Union Sanitary Flush will automatically go to full open when high-temperature water is being flushed, providing maximum flow for high-temperature sanitary flush.

CircuitSolver® Sanitary Flush Valve Introduced to Protect Against Legionella

ThermOmegaTech®, a world leader in the design and manufacture of self-actuating thermostatic valve technology, introduces the CircuitSolver® Sanitary Flush (CSUSF) Valve as the newest addition to their CircuitSolver® line. The CSUSF allows for higher-temperature water to flow through a domestic hot water system during the disinfection process to protect against Legionella growth in systems capable of high-temperature flushes.

Nick Tallos, Vice President of Engineering for ThermOmegaTech® says, “CircuitSolver® technology was already an innovative balancing method for domestic hot water systems. Now, with the addition of the Sanitary Flush, CircuitSolver® further stands out as a revolutionary technology with a myriad of applications. With its capability to protect against Legionella growth, the CircuitSolver® becomes an even easier and reliable balancing solution. It’s just another step in the right direction.”

CSUSF 338x119 - CircuitSolver® Sanitary Flush Valve Introduced to Protect Against LegionellaThe CircuitSolver® is a thermostatic, self-actuating balancing valve that continuously and automatically adjusts the flow through each branch of a domestic hot water recirculation system to maintain the specified temperature at the end of each branch, regardless of fluctuations in hot water demand.

It is a direct replacement for manual balancing valves and eliminates balancing labor and callbacks. The CSUSF valve uses two high-thrust actuators, a low-temperature actuator to maintain standard balancing temperature, and a high-temperature actuator to allow for high-temperature sanitary flushing of the system.

The CircuitSolver® Sanitary Flush Valve is tamper-proof and automatically balances any domestic hot water system at a set temperature, while still allowing higher water temperatures to enter for disinfection, preventing Legionella growth. It is the ideal solution for a maintenance-free balancing and high-temperature flush application. The CSUSF is lead-free, stainless steel, and corrosion-resistant. The CSUSF valve is NSF/ANSI 61 certified and comes equipped with long service life and a 3-year warranty.
