Sunrise Pre-Heating Solar Water Heaters

SUNRISE Pre-heating Solar Water Heaters

Description:

Working principle and product info:
Pre-heated solar water heater also relies on the natural circulation of water between the collector and the tank (that is tubes absorb solar energy, and heats the water inside the tube, hot water rises, cold water flows down).
It differs from compact non-pressurized solar water heater because it gets a copper coil inside the inner tank. The hot water rises from the tube into the tank, and heats the copper coil and finally heats the water inside the copper coil. Therefore the water tank is just as heat storage tank.
So the hot water we use is actually from the copper coil and even drinkable (as the copper can purify the water). The whole system also works at 0.2MPA.
Necessary parts: Tank (with a copper coil inside), the three-high vacuum tube, bracket, assistant tank

Specification:
Copper coil: Diameter 12 mm, thickness 1 mm, length 30 m;
Tank:
Inner tank: SUS304 2B food grade stainless steel 0.5 mm
Outer tank: SUS 304 BA Stainless steel 0.5 mm or color steel (cheaper);
Heat Preservation layer: 60 mm foamed polyurethane
Capacity: 100L, 150L, 200L, 250L, 300L.
Tube:
Advantages: With all-glass co-axial double tube, glass of High borosilicate 3.3 and coated with ALN/ALN-SS/CU, The tube we use can ensure more powerful absorbing power, and heats the water faster compared with normal tube coated with AL/N/AL;
Number of the vacuum tube available for your choice: 20, 24, 30, 36;
Tube size: Diameter: 47mm, 58mm, length: 1500mm, 1800mm;
Bracket: SUS 202 BA 1.5mm; Angle: 27o/38o/45o.
