The NJC solar freeze protection valves utilize a reliable self-contained Thermal Element which is sensitive to temperature and operates without any electrical power or air pressure. Typically in solar applications, the valve port opens on descending temperatures reaching the critical temperature allowing the near freezing water in the solar panel to be discharged and replaced with warmer supply water. When the warmer water reaches the set up point, the valve port closes and water discharge stops.
This cycle will repeat as often as necessary to help prevent freezing. The amount of water dispensed depends mainly on ambient air temperature, make up water temperature, the duration of the cold spell and the number and size of collectors. The system is functioning properly when water is being discharged from the valve during near freezing conditions.
Design Features:
