solar copper heat pipe evacuated tube

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

    The tube prssure-endure ability can reach 1Mpa

7.  Structure stability

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

6.Advanced technology

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

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

3.Long servece life by ensuring vacuum intergrity

2.Borosilicate glass 3.3 with transmitance higher than 0.91

1.High absorptance
