*Product DescriptionClosed-loop heating systems require an expansion tank. An expansion tank has a chamber in which air is locked inside a bladder or diaphragm. It screws into standard 1/2-inch or 3/4-inch threaded plumbing fittings. When pipes are filled with medium liquid (water and glycol), and the operating pressure of the system is set, the liquid will occupy a given volume based on the temperature. As the liquid is heated by the sun, it expands. This is where the expansion tank is critical. Without it, something would blow! The expansion vessel tank allows the liquid to safely expand by compressing the air in the chamber. The size of the expansion tank needed depends on the total volume of liquid, which is determined by the number and size of collectors, and the length and diameter of the pipes in the solar loop.
Expansion vessel is suitable for split pressurized solar water heating system. The maximum working pressure is 1.0 MPa. We have three types for your selection, 5L, 8L ,12L,18L and 24L.
