Compact Pressure Solar Water Heater Detailed Product Descriptionheat pipe solar geyser Specification: 1.Outer tank: SUS304-2B stainless steel 2.Inner tank: SUS304-2B or 316 food-grade stainless steel thickness≥0.4 3.Sealing Ring: Excellenrt Silica gel material. life is twice longer than common Silica gel. 4.Vacuum tuber: High-efficient vacuum tube *High-Efficient heat-collection function: New generation o vacuum tubes, use molecular nanotechnology, greatly enhance heat-absorption by 20 percent, higher water temperatures. *Adopts the international advanced film-coating technology, solar thermal conversion rates extremely high, absorbing heat even if the cloud weather. *Vacuum tube strictly choose high-borosilicate glass 3.3 so that it has low coefficient of thermal expansion and higher intensity. Hail-resistance:25mm 5.Insulation: 55mm polyurethane keep heating do with aging the cell is small and uniform reasonable density excellent insulation 6.Frame: thicker stainless steel , Anti-corrosive.and Anti-ultraviolet, installed in the slope and flat place freely.Strengthen hail-resistance. Angle 20-80 degree.Through oxidation process.It increase wind resistance.,life is longer than common frame. Beautiful appearance. 7.Automatic operation: Digital controller shows water temperature and water lever,water loading automatically ,heating automatically ,controlling automatically. Data Model
