brightness crazy selling solar evacuated tubes vacuum tube for solar energy systems
Product Description
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:
Detailed Images
1. Structure chart of solar vacuum tube
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
2 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.

5. Production Procedures
Yaoguo Solar has a complete industrial chain of solar vacuum tube, which ensures the quality and quantity of the goods. Solar borosilicate vacuum tube is a kind of high-precision products. So all the procedures finishing in one place could produce items with stable quality, and reduce cost at maximum to benefit the customers.
6. Shock Resistance Test
Solar vacuum tubes made by Yaoguocompany could work in harsh environment. Hot water is available because of good vacuum tightness in cold weather. And also the borosilicate glass 3.3 can bear collision in a certain level. Photosbelow are a test about this.
