Sunpower Tech is headquartered in Nanjing, Jiangsu. We have long been committed to the research and development, production and sales of high-end equipment in the fields of chemical industry, polysilicon, LNG, metallurgy and other fields. We adhere to the concept of "increasing production, energy saving, efficiency and environmental protection", relying on critical technologies such as "efficient heat transfer". We strive to help customers achieve energy conservation, efficiency, low carbon and environmental protection through the use of advanced technology and high-end materials.

In response to industrial pain points and bottlenecks, we focus on cutting-edge technologies in chemical materials, clean energy equipment, energy conservation and environmental protection. We have undertaken critical equipment localization and transformation projects entrusted by large state-owned enterprises and industry leaders such as Sinopec, CNOOC, Wanhua Chemical, GCL Technology, and Tongwei Group. We have fulfilled the development of key equipment such as the equipment for solar polysilicon, LNG gasification and liquefaction, energy-saving PTA oxidation condenser, propylene oxide/styrene co-production unit dehydration reactor, and ethylene glycol coupling reactors and esterification cyclohexanone benzene selective hydrogenation reactor, making great contributions to the localization of key equipment of chemical materials and new energy. Our hot rod technology is one of the main measures and iconic technologies to solve the biggest problem in the construction of the Qinghai-Tibet Railway, that is, "frozen soil thawing settlement and frost heaving". We are the initiator of the national standard for hot rods. As one of the main builders of the Qinghai-Tibet High-Altitude Permafrost Expressway, our key technologies and engineering applications for the construction and maintenance of the expressway won the "2020 National Science and Technology Progress Award".

As a technology enterprise, Sunpower Tech is responsible for the construction, management and research tasks of "Jiangsu (Sunpower) Industrial Energy Saving Technology Research Institute" and "Nanjing Frozen Soil Engineering Center of the Chinese Academy of Sciences". Approved by the Ministry of Human Resources and Social Security and the National The Standardization Management Committee, we have established a number of research platforms, including the "Postdoctoral Research Workstation" and the "Hot Rod Working Group of the National Technical Committee for Standardization of Transportation Engineering Facilities (Highway)".

Relying on independent innovation capabilities, we adhere to the path of localized innovation, with efficient heat transfer technology as the core. We promote the industrialization of clean energy, energy conservation and environmental protection and other technological achievements, helping customers increase production and save energy, and contributing to China's goals of carbon peak and carbon neutralization.
