Product Description


Vacuum borosilicate glass tube for solar heating collector

Yaoguo Solar Thermal is specialized in making solar vacuum tubes. Tubes not only have different colors, but also have very stable film, which leads to a fast heating and an excellent heat preservation. Here are the photos for your inference:

A solar vacuum tube is mainly made of these parts:

1.Getter 2. Spring holder 3.Outer Tube 4.Inner tube 5.Vacuum

6. Anti-reflection layer 7.Absorbance layer 8. Infrared-reflection layer     

 

How does Yaoguo solar vacuum tube work?

After installation and check the heating collector system correctly, cold water is filled in the water tank. Due to gravity, cold water flowed into the vacuum tubes, absorbing the heat (which the temp. might reach 250 degree centigrade). Cold water changes into hot water and goes back to the water tank.
