Engineering capabilities across design, manufacturing and technology
Groundsun expanded beyond high-end heating markets by strategic entry into the basic chemical industry, marking a decisive shift toward broader industrial applications.
Products were exported as part of a full process package for the Kungrad Soda Plant in Uzbekistan, marking Groundsun's first step into international markets.
Porous coated high-flux tube technology was developed and put into industrial validation for Groundsun's enhanced heat transfer product family, followed by immediate industrial application in refining and petrochemical applications.
High-flux tube heat exchangers were deployed in all four major million-ton ethylene plants in China — Tianjin, Zhenhai, Fujian Refining & Petrochemical, and SECCO — proving performance at full industrial scale.
High-flux technology was successfully applied in China's largest 600,000-ton/year PDH unit, ending dependence on foreign suppliers in the critical process application.
High-flux tube heat exchangers were first applied in coal-to-olefins and MTO units in 2014, followed by high-vacuum coal-to-ethylene glycol units in 2015, opening a new, large-scale application sector.
Groundsun's falling-film evaporation system was deployed for DMC production, marking the company's expansion into high-end chemical new materials.
High-flux tube heat exchangers were applied in the world's largest single-train 1.0 Mt/a EO/EG unit under SD's process package, further cementing Groundsun's global position in high-end heat transfer technology.
Groundsun’s predecessor served high-end heating and heat exchange projects in Beijing, including Zhongnanhai and Beijing Hotel.
These early projects reflected the company’s initial capability in improving heat exchange performance within limited equipment space, forming the earliest practical foundation for its later focus on enhanced heat transfer.
Corrugated tube heat exchangers entered nitrogen fertilizer and soda ash applications, including ammonia condensers and soda ash process equipment.
This marked Groundsun’s transition from heating applications into industrial process systems, where heat transfer performance, operating stability, and equipment reliability became increasingly critical.
Groundsun’s heat exchange products were applied in combined heat and power systems and early petrochemical process units, including heat network heaters and condensers for petrochemical applications.
This stage broadened the company’s application base from municipal and heating systems to continuous industrial process operations.
Groundsun’s corrugated tube heat exchangers were exported with a process package for the Kungrad Soda Plant in Uzbekistan.
This represented an early overseas application of the company’s products and demonstrated that its heat exchange equipment could be integrated into process-package-based international projects.
High-flux heat exchangers were applied in million-ton ethylene plants, including major ethylene projects such as Tianjin, Zhenhai, Fujian Refining & Petrochemical, and SECCO.
This was a key industrial validation of Groundsun’s enhanced heat transfer technology in large-scale petrochemical operations, proving its reliability under demanding process conditions.
High-flux heat exchangers were applied in large-scale PDH units, supporting import substitution in critical process equipment.
This milestone demonstrated Groundsun’s ability to replace imported equipment in demanding petrochemical process units and further strengthened its position in high-efficiency industrial heat transfer.
Groundsun’s high-flux heat exchangers were first applied in coal-to-olefins units, and its high-vacuum condensers were later applied in coal-to-ethylene glycol units.
These applications expanded Groundsun’s enhanced heat transfer capability from refining and petrochemical processes into modern coal chemical industries, supporting large-scale and energy-intensive process systems.
Groundsun’s falling film evaporation system was applied in DMC units, including large-scale chemical new materials projects.
This marked the company’s expansion into higher-value chemical new materials applications, where process efficiency, thermal control, and equipment integration are central to production performance.
Groundsun’s high-flux heat exchangers were applied in a 1-million-ton-per-year EO/EG unit under SD’s process package, replacing imported equipment in a major international process-technology scenario.
This milestone showed that Groundsun’s enhanced heat transfer technology could be integrated into advanced process packages and recognized in highly demanding chemical process applications.
Groundsun continued to expand its technology applications into caprolactam, LNG cold energy utilization, nuclear-related heat transfer research, overseas projects, and emerging applications such as data center cooling and new energy thermal management.
This stage reflects the company’s ongoing evolution from a heat exchanger manufacturer into a broader provider of industrial heat transfer solutions, applying its core design and engineering capability across more industries, processes, and global markets.
