Model: SPECIFICATION: 1. Material of Inner Tank: SUS304-2B Stainless Steel, thickness: 0.4mm. 2. Material of Outer Tank: SUS304-2B Stainless steel, thickness: 0.34mm 3. Copper Coil: Diameter: 12mm, thickness: 1mm, length: 40 meters Diameter of the inner & outer tank: 480mm/380mm 4. Heat Preservation: Polyurethane foam with 55mm thickness 5. Magnetic-controlled Al-N-Al splash all glass evacuated heat-collecting tubes 6. Specification: Φ 58mmx1800mmx30 tubes 7. Material of Support: Galvanized steel: Thickness 2.0 mm WORKING PRINCIPLE: 1. The vacuum tube collector absorb the heat energy to heat the water in heat storage tank, 2. When using the hot water, the cold water flows through the inlet, the copper coil absorb the heat then transfer into the cold water, so that the temperature rise up ceaseless, 3. For the original features of the copper coil, the water temperature of the outlet is close to the water temperature of the water tank(≤ 3C), so the high pressure of the cold water into the copper coil and absorb the temperature, at last the water can be used.
