Keep your solar collectors and exposed pipes from freezing with a SmartTechProducts Solar Freeze Protection Valve. The valve operates without any electrical power. The Solar Freeze protection Valve contains a thermal actuator. When temperatures approaching freezing, approximately 34°F, the valve will open. When properly installed this will allow warmer water supply to slush colder water from your solar panels. When the temperature reaches 39°F the valve will close. This cycle will continue preventing panels and pipes from freezing.

Ask a Question
  • What valve can be used in Climate Zone 6 for this purpose and why can't this one be used there?

    Thermostatic valves like SmartThaw™ require warmer ground water temperature to close them. In certain colder zones the ground water is not warm enough to close the valve. If your ground water temperature reaches 40°F or higher in the winter this valve would work. Currently we do not have a valve to work in colder zones.

  • Hi, What is the max pressure rating? Thanks

    Thank you for the question. According to the manufacturer the maximum working pressure for the SmartThaw valve is 145 PSI.
