Product Overview


Direct Factory supply solar water heater accessories , 58mm*1800mm solar vacuum tube






 Product Advantage

1, Cold pipe, heat loss is very small, can still work normally in the cold environment, -30℃ as usual hot water; 2, Super absorption, high thermal efficiency, fast heating, under the same lighting conditions, can produce

3, more hot water with higher temperature than ordinary pipe;

4, High temperature special effect tube, because of the stainless steel ion in the film layer of high temperature, 5, anti air, the film layer in 400℃ conditions without aging, no decay, no color;

6, Mainstream products on the market! The market demand is very large! Performance is very superior! All

7, glass solar vacuum tube! More than 10 years of service life;

Energy Saving Three Target Solar Vacuum Tube


solar vacuum tube Three target solar vacuum tube consists of the inner and outer tubes, which are cut and coated on the condition of high temperature. The inner tube is coated in the three target magnetron sputtering plating equipments which is the newest three target technology and intorduced from German. Using the coating material of argon and nitrogen aims at becoming three membranes Cu-SS-ALN. It takes about 60 minutes. Then, melting the inner and outer tube together and evacuating empty in the vacuum machine. Evacuated tube is core of the solar water heater. Its performance lies on the coating technology, The three-target evacuated tube rises the heat more than 12%.


solar vacuum tube Material: high borosilicate 3.3 glass. Structure: all-glass double-tube co-axial structure. Color: blue or purple golden. Size: 47mm×1500mm, 47mm×1800mm; 58mm×1500mm, 58mm×1800mm, 58mm×2000mm; 70mm×2000mm, 70mm×2100mm. Thickness: 1.6mm/2.0mm. Warranty: 8 years. High absorptance: 93%~96%(AM1.5). Low emittance: 0.04~0.06(80°C±5°C).


 solar vacuum tube High Efficiency Solar Vacuum Tube consists of the inner and outer tubes, which are cut and coated on the condition of high temperature. Solar Vacuum Tubes are the absorber of the solar water heater. They absorb solar energy converting it into heat energy for use in water heating. The hot water rise to water tank and the cool water fall to the bottom of the vacuum tube. As the gravity theory, the hot water and cool water are continuously circulation in the vacuum tube and water tank.
