DINGRE solar collector

                   (1), stent: Scientific ratio, specialized production, support more choices: stainless steel stent series, galvanized plate bracket series, aluminum alloy bracket series;
                   (2), Outer tank: The import of color coated steel plate, Al-Zn plates and stainless steel plate a variety of models;
                   (3),Inner tank: 0.31mm-0.41mm thick sus304 or sus316 food-grade stainless steel plate, using the most advanced computer automatic welding technology, avoiding the formation of grain boundaries of traditional welding corrosion, longer life;
                   (4), insulation layer: a one-time use 50mm thick polyurethane foam, after high-temperature aging technical treatment, avoiding the secondary foam, foam density of small uniform, closed cell high rate of better insulation;
                   (5), vacuum tube: high-vacuum magnetron sputtering through the inner tube outer wall to form the sun has a high absorption rate and low emissivity coatings, higher absorption of solar energy, lower heat loss, even if the cold winter in the north also produce hot water;
                   (6), pipe joints SUS304 stainless steel automatic arc welding, solid and reliable;
                   (7), sealing rubber ring: silicone rubber materials, high temperature resistant, good elasticity, sealing reliability, long life.
