Product Description

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.

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
Hi-Tech Solar Vacuum Tube/Solar Evacuated Tube/All Glass Evacuated Solar Collector Tube
Since its establishment in 2002, Shandong Longguang Tianxu Solar Energy Co., Ltd (hereinafter referred to as "Tianxu") has always engaged itself in the R&D, production, sales and service 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. Both Tsinghua and Tianxu are 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, sea water desalination, air source heat pump, computer controlled heating systems and photovoltaic application systems. 

Here at Tianxu, 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.
