Cutting-edge innovation in temperature mixing

The Caleffi 5212 Series SinkMixer™ is a scald protection, under-sink thermostatic mixing valve used to deliver safe tempered water where the user must be protected from the danger of scalding caused by hot water.  The convenient 4-port design simplifies piping and minimizes connection points.  It features a cold water bypass to the fixture that eliminates the need for additional piping and a tee that would be required with a 3-port design.

SinkMixer is precision engineered with forged DZR low-lead brass that resists corrosion and provides high flow capacity in a compact body.  The low friction, high-performance moving internal parts resist scaling to ensure stable, accurate temperature control.  Peroxide-cured EPDM elastomers resist chlorine and chloramine, which can be present in public water supplies, ensuring long valve life.

Installers appreciate the stand-off wall bracket for sturdy mounting and simple hose connection.   Maintenance is easily accommodated with replaceable inlet check valves and stainless steel mesh filters.  The filters provide maximum debris protection.   Tamper-resistant locking nut and cap prevents unauthorized set point adjustments.

SinkMixer is available with fitting hardware that includes (1) plug for cold outlet port (used for automatic sinks which have a one pipe connection for tempered water) and (4) nuts and (4) ferrules (sleeves) for use with pipe-types other than flexible stainless steel hoses.

Rest assured.  SinkMixer is ICC-ES certified compliant to ASSE 1070/ASME A112.1070/CSA B125.70 (Performance Requirements for Water Temperature Limiting Devices) and NSF/ANSI/CAN 61-2019 and IPC, IRC, UPC and NPC for drinking water systems in accordance with U.S. and Canadian plumbing codes

SinkMixer is an important part of the LEGIOMIX® domestic hot water (DHW) control system that was recognized by the AHR Innovation Awards panelists as a finalist in the 2022 Sustainable Solutions category.  Caleffi’s DHW system – a product trifecta – consists of three components:  A LEGIOMIX digital mixing valve, ThermoSetter™ thermal balancing valves and SinkMixer anti-scald mixing valves.  Combined this product trifecta promotes energy efficient DHW recirculation system design, while enabling safe and effective thermal disinfection cycles to control Legionella.

Viega LLC’s ProPress Automatic Recirculation Balancing Valve ensures a balanced domestic water recirculation system by dynamically changing with varying conditions.

The valve can help prevent the growth of legionella bacteria by keeping hot water out of the growth zone temperature of 95°F to 115°F (35°C to 46°C), while still preventing scalding and conserving energy.

The Automatic Recirculation Balancing Valve is a modification of a Viega product that has been used successfully in Europe for years. It helps keep water temperatures more uniform by adjusting flow with changes in temperature. The results are faster hot water delivery, minimized waste energy and water and less stagnation and chance of contamination. Among the valve’s features:

• Unlike with manual valves, temperature can be set once and be maintained automatically. Settings can be changed easily, if needed.
• Can be installed on risers or branches
• Remote monitoring with temperature sensor
• Optional thermometer provides visual indication of valve setting
• Threaded ends allow it to be used with Viega ProPress or Viega PureFlow fittings systems for easy integration with copper or PEX
• Includes bypass for thermal disinfection

Additional accessories that can be used with the valve include a thermometer, drain valve and optional insulation sleeve.

“Viega is committed to providing hot water quickly and efficiently while improving water quality and the new Automatic Recirculation Balancing Valve is a significant step toward that goal,” said Paige Riddle, Senior Manager, Market Manager. “This valve offers more features than any other on the market while requiring minimum work on the part of designers, engineers, installers and building maintenance personnel.”

Watts has announced the next installment in a series of webinars for their engineer, architect, designer, and facility manager customers:  Smarter, Safer Hot Water, to be broadcast live on Wednesday, August 28, 2019.

This latest webinar will focus on how digital mixing valves enable engineers, designers, and facility managers to directly measure, monitor, and deliver safer hot water through domestic water systems.

Key points to be covered include an overview of how digital mixing valves:

• Efficiently deliver mixed water throughout a hot water recirculation loop while allowing remote monitoring and control of water temperatures,
• Minimize the risk of waterborne bacteria in high-performance commercial and institutional facilities, and
• Provide precise control needed to deliver high water temperatures that mitigate the risk of the deadly Legionella bacteria (the cause of Legionnaires’ disease) while avoiding the risk of scalding and thermal shock injuries.

By attending the entire webinar, attendees can receive 0.1 Continuing Education Units (CEUs) through the American Society of Plumbing Engineers (ASPE).

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.”

The 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 61certified,  comes equipped with a long service life and 3-year warranty.
