Solar Evacuated Tube With Heat Pipe

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 scaling2.No blasting3.water-tight4.Anti aging5.low temperature-resistant6.high temperature-resistant 7.Resistant to high temperature8.fast heat transfer9.high heat conductivity10.bearing pressure

1)Highly efficient zbsorber 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

3)With stand pressure of 0.2Mpa,can be connected directly with city water pipe

4)Highly efficient insulation with polyurethane foam

5)Can be used all year round even in the cold weather

6)Automatically controlled

7)Highly heat absorber and less in heat losing

8)For both flat roof and slope roof
