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 online monitoring 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.
Solar vacuum tube production line
High Quality Core Parts Make Sure The High Quality Project
For many years relies on strong scientific research and develop strength, continuously update the products, especially the vacuum heat collecting tube which is used as the core parts of
solar water heater. Depending on the high quality and goo public praise, it formed in strategic cooperation with many renowned brands, market share reaches more than 6% in the industry in
China. Products are sole to a dozen of countries.
Good material
All materials use section borosilicate glass, high intensity, good transparency, performance is excellent, it can bear 25mm hail shock, and thee service life is more than 15
years.
Efficient heat collecting
Classic “Shaile Tube” is fully updated, using the new gradual change-partiallly absorbing coating technology, solar
absorption is up to 93%, heat emission ration is on 0.06, all close to the theoretical limits, performance is super good.
Seal tightly
The joint between vacuum heat collecting tube and connecting pipe uses “O” style seal ring, has long service life, tightly
sealed, safe, reliable and other characteristics.
Long time of insulation
Our vacuum expert designed high efficient energy saving vacuum exhaustor and computer on-line monitoring system. The quality of vacuum is very good, can maximumly reduce the heat loss
caused by heat conduction and heat convection.
