low pressure solar geyser, solar water heater adopts simple thermal circulation, cold water heated by solar vacuum tubes, then hot water go up to tank, cold water in tank flow into solar vacuum tubes, cold and hot water form a natural circulation called thermosyphon, the whole tank water will become hot gradually.
Specialty:
· 1.Economical type for most of area,common people can afford it
· 2.Simple product structure: solar collector and water tank connected together directly, no need of pipe to connect, and no pump to push fluid
· 3.Mature technology and stable operation
· 4.Higher efficiency on photo thermal conversion.
· 5.Accessory is popular and easy maintenance
Technical specification:
· 1. Inner Tank: 0.41mm SUS304-2B food grade stainless steel (optional material: SUS316L).
· 2. Outer Tank: 0.41mm SUS304-2B food grade stainless steel (SUS304-2B).
· 3. Bracket: Galvanized steel , thickness 1.5mm , angle 20°/30°/45°.
· 4. Insulation: 55mm polyurethane layer.
· 5. Vacuum tube material: borosilicate glass 3.3; AL-SS-CU absorb coating
· 6. Seal material: Stabilized High Temperature Silicon
· 7. It resists 25mm hail.
· 8. Heat preservation: 72 hours
