Product Details

Three Target Solar Heat Pipe Vacuum Tube

Feature:

1.Vacuum tube feature:

The kind of vacuum tube assimilate the advanced 12 layers of spattering deposition of trivalent element technology, high quality borosilicate glass 3.3, gradual change of CU-SS-ALN/ALN selective absorption coating and make vacuum tubes have high performance of absorptance and low reflection ratio. Through interlayer, vacuum has a unique effect of thermal, with its temperature up to 380 degree of idle sunning, performing a strong ability.

Brief Introduction of solar heat pipe

1) The products use super heat condition pipe and has a good effect of heat exchange.

2) The insulation layers use the up-to-date technology and has a good effect of temperature preservation which allows the water to stay warm for about 70 hours

3) Superior heat-preservation ensured by one-off molding polyurethane foam with thickness 50-60mm

4) Stable and reliable performance,well wind resistance

5) Meet the mankind healthy bath standard,the material of inner tank is SUS304-2Bstainless steel plate,the silica gel ring sealing has a long life against the erosion and it do no harm to health.

Main Advantages of solar heat pipe:
1.No scaling

2.No blasting

3.water-tight

4.Anti aging

5.low temperature-resistant

6.high temperature-resistant

7.Resistant to high temperature

8.fast heat transfer

9.high heat conductivity

10.bearing pressure

1)Highly efficient absorber of high performance with daily average effciency over 40%-50%

2)Start up quickly heat pipe transfer the heat energy into the storage tank in one condition
