All glass solar vacuum tube&evacuated tubes for solar collector use

The structure and Character of All-glass Vacuum Tube:

Advantage of All-glass Vacuum Tube:

1. High Performance:

Using ultra-limited coating and other cutting-edge technologies, the collection is more efficient. The absorption ratio is greater than 0.93, and the emission ratio is less than 0.06, which is much higher than the national standard.

2. Long Service Life:

Design of high efficiency and energy saving by the experts electric vacuum exhaust machine with the computer ontoring system, vacuum degree in 3 x 10-3 pa, is ten times bigger than the national standard, to ensure the vacuum tube service life of not less than 15 years.

3. High Strength:

The vacuum tube wall thickness is the highest in the industry, and the finished weight and strength are high. In the steel ball test, the high impact of 2 times as high as the national standard is not damaged, and the weather can withstand hail.

4. Low detonation rate:

The enterprise standard requires that the glass tube should be cut in grade C above grade C, so as to avoid the inner stress of the glass tube, and eliminate the hidden danger of the tube in the process of vacuum tube.
