About Us

A leader in China's solar thermal market
The largest and most advanced production base for solar vacuum tubes 
The Integrate service provider for new energy system
The drafter of the latest national standard for 3.3 high borosilicate glass

Tianxu solar, established in 2002, is a world-renowned, award-wining, high-tech company, leading designer and manufacturer of high borosilicate glass tubes and new energy products including solar water heaters, solar vacuum tubes, solar heat collecting project, air source heat pump, photovoltaic products, etc. 

Tianxu's scale is far ahead of other companies in the industry. There are 10 sets of electric furnaces, 70 sets of solar vacuum tube production line and 3 sets of solar water heater production lines. The annual output of one million tons of high borosilicate glass, over 16 million solar vacuum tubes makes Tianxu the largest manufacturing base of high borosilicate glass tubes and solar vacuum tubes. 

In 2015, Beijing Tsinghua Industrial Development Institute Shandong Branch settled in Tianxu to better promote the R& D, marketing and application of clean energy with Tsinghua University's strong scientific research strength and Tianxu's manufacturing ability. Meanwhile, Tianxu established a joint venture company with Beijing Tsinghua Solar Co., Ltd- the solar vacuum tube technology initiator in the world. The newly established company has the world's most advanced solar vacuum tube production lines. 

Tianxu solar has grown into the most influential  company in  Chinese solar industry . All  of our products are manufactured  with  a  strong  emphasis  on  ease  of  installation  to  provide  optimum integration of solar water systems into building design, while aiming to minimize the environmental impact of all products and operations. Besides, we attach a particular attention on customer service .

Tianxu  is at the  forefront of  most of  solar thermal  technologies, as  we are currently  using our expertise to also work on solar space heating, solar cooling , seawater desalination , air  source heat pump, computer controlled heating systems and photovoltaic application systems.

Here  at Tianxu Solar  systems  Ltd  we are  committed  to  investing technology and  manpower  to achieve a  bright and clean future, and to  providing simple and effective solutions for families and businesses concerned about climate change and rising energy costs .

 
Product Parameters

 


Solar Vacuum Tube
58*2100mm Vacuumed Tube with Three Targets
Tianxu company distributes highly efficient evacuated tubes. We offer high performance evacuated tubes with an improved geometry and performance. The evacuated tubes consists of two concentric glass tubes which are sealed in a semi-circular shape on one side and are joined to one another on the other side. The space between the tubes is evacuated and hermetically sealed (evacuated insulation). To use solar energy, the internal glass tube is coated with an environmentally friendly, highly selective layer on the outside, thus turning it into an absorber. The selective coating is protected in the evacuated space. The aluminum nitride sputter coating used is characterized by an extremely low emission and a high absorption rate.

 
Tube Structure All-glass double deck co-axial structure
Glass material  Borosilicate 3.3 glass
Outer tube diameter and glass thickness Φ58+/-0.7mm; glass thickness 1.6+/-0.15mm
Inner tube diameter and glass thickness  Φ47+/-0.7mm; glass thickness 1.6+/-0.15mm
Tube Length 1800mm
Absorber coating  Coating Material  Cu/SS-AIN(H)/SS-AIN(L)
Sediment method Three targets magnetron sputtering plating
Absorptivity 0.93~0.96
Emittance ≤6.0%(80ºC+/-5ºC)
Vacuum degree P ≤5.0X10-3(Pa)
Transmittance of glass tube  T ≥0.89(AM1.5 ISO9806-1:1994
Stagnation parameter Y: 240~250 m2ºC/KW
Average heat loss  ULT≤0.6 W/(m2*ºC)
Hail resistance Φ25mm
Pressure endure 0.6 MPA

 
   



Cover glass  tube : protects  the whole tube. The space  between  the cover glass tube and the inner glass tube is mechanically evacuated to create a vacuum environment
Inner glass tube : filled with heat transfer fluid (generally water) and directly plugged to the water storage tank.
Selective  absorbing  coating:  absorbs solar  radiation and transfers  to the fluid in the inner tube.
Retainer: keeps the inner tube fixed.
Getter: Absorbs the residual air in the space between the cover glass
tube and inner glass tube.
