solar heat pipe:
1)High absorbance
2)Resist the frozen weather
3)Cu-Ss-Al absorb coating

solar heat pipe: 

The all-glass evacuated solar collector tube consists to concentric cytindrical glass tubes,the inner cylindrical tube is the absorber tube on which solar selective coating is sputtered.the jacket between the two tubes are evacuated to extremely low vacuum to reduce the heat loss by free convection and conduction.this technology can be utlized under all kinds of climate conditions,especially better in colder area.

Features:

1.High absorptance≥0.92

2.Borosilicate glass 3.3 with transmitance higher than 0.91

3.Long servece life by ensuring vacuum intergrity

4.Quality manufacture ensure standadized tube with uniformity and reproducibility.

5.Higher absorbance,lower emittance,dry exposure up to 300.C and freezing resistance can up to -35.C.

6.Advanced technology

 Our company use 3 target magnetron sputtering plating technology,which introduce from Germany and also called interferometer coating technology.

7.  Structure stability

    The tube prssure-endure ability can reach 1Mpa

8.High efficient selective absorptive coatings and vacuum heat insulation technology
ensure the tube has higher heat output in cloudy weather and in moist areas,
especially in winter
