Tianxu, founded in 2002, primarily engages in the research, production, sales, and services of high-boron silicon specialty glass, along with new energy products like solar thermal, photovoltaic, and air source energy. Its business spans over 20 countries and regions in China, Asia-Pacific, the Middle East, South Africa, and North America. As a leading backbone enterprise with independent R&D capabilities, the company focuses on clean energy products and actively expands its business scope based on industry chain advantages.
Located in Zhucheng City, renowned as the “Hometown of Emperor Shun and Dragon City,” Tianxu boasts a registered capital of 100 million RMB. Its main products include high-boron silicon specialty glass products used in solar heat-collecting tubes and process tubes, as well as vacuum solar heat-collecting tubes, medium-to-high-temperature heat-collecting tubes, solar water heaters, solar heat collection projects, air source heat pumps, photovoltaic power stations, and other new energy products. The company has smoothly passed quality, environmental, and occupational health and safety management system certifications and holds independent import and export rights.
Tianxu serves as the Vice President of the China Council for the Promotion of New Energy Chamber of Commerce, a director unit of the National Solar Thermal Industry Technology Innovation Strategic Alliance, and the Vice Chairman Unit of the Shandong Solar Energy Industry Association, among others. It has actively participated in drafting over ten national and industry standards, including technical standards for solar heating and heating systems, glass-metal sealed vacuum direct-pass solar heat collection tubes, and performance testing and evaluation methods for rural household solar heating systems.
The company owns ten advanced high-boron silicon glass production lines, 70 automated heat-collecting tube production lines, and three solar energy product production lines. Its annual production capacity includes 120,000 tons of boron silicon glass, 30 million solar vacuum heat-collecting tubes, and 200,000 solar and air source water heaters. With four major production bases, Tianxu stands as a major production base for high-boron silicon glass and solar heat-collecting tubes in China. It’s also one of the few companies in the industry with a complete solar thermal utilization industrial chain.
Maintaining its tradition of independent innovation, Tianxu actively introduces and absorbs advanced industry technologies and achievements to enhance its core competitiveness. In 2015, the company established the Shandong branch of the Beijing Tsinghua Industrial Development Research Institute to focus on clean energy technology research, promotion, and application using Tsinghua University’s research strength and technological base.
With its core position in the industry and industrial chain advantages, the company actively introduces upstream and downstream projects to form complementary advantages, promoting mutual development. It has welcomed several high-quality projects, including “Tsinghua Sunshine New Efficient Heat Collection Tubes,” “Medium and High-Temperature Power Generation Tubes,” “Solar Super White Glass,” and “Medium and High-Temperature Solar Heat Collection Tubes,” creating a characteristic solar thermal smart manufacturing industry cluster. This cluster holds a significant strategic position in China’s solar thermal industry landscape.
Looking ahead, Tianxu remains committed to “developing green technology and contributing to clean energy,” upholding the enterprise mission of “delivering solar power and creating a green lifestyle.” It practices the service philosophy of “continuously creating value for customers,” actively responding to the national call for carbon peaking and neutrality. With continuous technological product innovation, Tianxu aims to drive the development of the clean energy industry, contributing its efforts to the development and utilization of new energy and environmental protection worldwide.
