01. Materials:
a. Outer tank: colorful or galvanized steel;
b. Inner tank: SUS304-2B or 316 food-grade stainless steel with ≥0.4mm thickness;
c. Sealing ring: excellent silica gel, twice longer lifespan and silica gel.
02. Vacuum tubes: highly efficient.
03. High efficient heat collection function: new generation of vacuum tubes, uses molecular nanotechnology, greatly enhances heat absorption by 20%, higher water temperature.
04. Adapts international advanced film coating technology, solar thermal conversion rates extremely high and absorbing heat cloud weather.
05. Vacuum tube strictly choose high borosilicate glass 3.3 with low coefficient of thermal expansion and high intensity.
06. 55mm polyurethane keeps heating with aging small cell and uniform reasonable density excellent insulation.
07. Frame: thicker galvanized steel, anti-corrosive and -ultraviolet, installed in slope and flat place freely.

08. Hail resistance: 25mm.
09. Angle: 20 to 80°.
10. With oxidation process, increases wind-resistant and long lifespan and frame.
11. Nice appearance.
12. Operation: digital controller shows water temperature and lever, loading, heating and controlling automatically.
