2. Material:
Outer tank: color steel/stainless steel
Inner tank: SUS304-2B food grade stainless steel
Insulation layer: polyurethane foam
Vacuum tubes: High quality borosilicate glass 3.3, Φ47×1500, Φ58×1800/2100,
Bracket: galvanized steel
3. Advantages:
1. can be operated completely automatic if connected with intelligent controller.
2. Simple structure, easy plug-in installation, can be installed both on flat and inclined roof, and can be used with an auxiliary electric booster as to provide hot water without sunshine.
3. Superior heat preservation ensured by one-off molding polyurethane foam with thickness 50 65mm.
4. Suitable for camping areas, holiday residences.
5. Stable and reliable performance, well wind resistance.
6. Meet the mankind healthy bath standard: The material of inner tank is 0.4mm SUS304-2B stainless steel plate; the silica gel ring sealing has a long life against the erosion and it is not harmful to health.
7. For area near the sea, adopting this type with stainless steel outer tank material is a nice choice since it has the much better efficiency of anti-corrosion.
4. Working Principle of thermosyphon
Because of the larger proportion of hot water than cold water, cold water flows downward and hot water goes upward. The water will be heated continuously between water tank and vacuum tube. In other wards, hot water always floats on cold water.
The hot-water flows to the water tank from the vacuum tubes. Because of the proportion, cold water flows to vacuum tubes from the water tank.
The cold water is heated in vacuum tubes. After it becomes hot water, it flows to water tank again. The water circulates constantly between water tank and vacuum tubes; the cold water in water tank will be hotter and hotter.
Finally, all cold water will be heated to be hot water. This is the heating course of cold water.
