Feature: 1. Vacuum tubes: Three “high” new technology tube with *0% higher performance, �*7X***0mm, �*8X***0mm; 2. Inner tank material: SUS****2B food grade stainless steel plate with thickness 0.*1mm, 0.*1mm, 0.*1mm; 3. Outer tank material: Imported color steel plate, stainless steel sheet; 4. Insulation material: *0mm **0mm polyurethane; 5. Red copper coil in the tank: the diameter is ***** is 1mm 6. Frame material: Imported aluminum alloy; The principle of the thermo-siphon system: The vacuum tube collector absorbs the heat energy to heat the water in the storage tank, when using the hot water, the high pressure press the cold water into the copper coil, the copper coil absorbs the heat then transfer the heat into the cold water in the copper coil. When the cold water flow-through the copper coil, its’ temperature rise up ceaseless, so the water temperature of the outlet pipe is close to the water temperature of the water tank (≤3℃).
