| New tri- element vacuum tube |
210cm vacuum tube assimilate the advanced 12 layers of spattering deposition
of trivalent element technology to make the tube has high performance of
absorptance and low reflection ratio. It also can stand up to high temperatures
and perform a strong heating ability. And improve the deposition layer's structure
through add rare metal to enhance the effect photosensitive reaction, the
absorbing rate of vacuum tube up to 0.96. Absorb

| Expansion Tank |
|
Closed-loop 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 heat transfer fluid (water and glycol), and the operating pressure of the system is set, the fluid will occupy a given volume based on the temperature. As the fluid is heated by the sun, it expands. This is where the expansion tank is critical. Wit

| Heat Exchanger |
|
Heat exchangers are used in closedloop solar hot water systems. They enable the transfer of heat from one fluid to another without the two mixing. Internal heat exchangers are inside the tank and not visible. They can be as simple as a coil of pipe resting in the bottom of the tank, or wrapped around the outside beneath Ö®ÏÂthe insulation and cover. As the heated fluid from the solar collector travels through the coil, the heat is passed from the hotter fluid to the cooler potab

|
Pumps are used in active systems, but are not required in batch or thermosyphon systems. They circulate water or antifreeze between the solar collector and the storage tank. The right pump for the job depends on the size of the sy
