More Good News | Nexson Signs Large Spiral Plate and Fully Welded Plate Heat Exchanger Orders with a Leading Chinese Petrochemical Company, and the Group Delivers the World’s Largest-Diameter Spiral Plate Heat Exchanger

Good news keeps coming at Nexson Group — Nexson China has signed multiple spiral plate and fully welded plate heat exchanger orders with a leading domestic petrochemical company. At the same time, the group’s French factory has successfully delivered an ultra-large spiral plate heat exchanger of landmark significance for the industry, demonstrating its exceptional technical strength and high market recognition in large fully welded heat exchangers worldwide.

Nexson China signs orders for over 20 fully welded heat exchangers with a large refining and chemical enterprise

Nexson China has recently signed multiple fully welded heat exchanger orders with a leading domestic petrochemical company. The contracts cover various equipment types including GreenSpiral™ spiral plate heat exchangers and GreenP&S fully welded plate-and-shell heat exchangers, totalling more than 20 units.

In 2024, Nexson Group China had already supplied spiral plate heat exchangers for this customer’s new project, and the two sides maintained a good cooperative relationship throughout execution. This year Nexson Group China has gone further with the customer, providing more than 20 spiral plate heat exchangers and fully welded plate-and-shell heat exchangers for another new project. The spiral plate units are manufactured to ASME standards, achieving efficient heat transfer while avoiding internal blockage; the fully welded plate-and-shell units were optimised against the customer’s actual process requirements, ensuring zero leakage and stable long-term operation at 120% load.

Nexson Group’s French factory delivers an ultra-large spiral plate heat exchanger

At the same time, Nexson Group’s French factory delivered two GreenSpiral™ Type 1 spiral plate heat exchangers to an Australian engineering company — the largest units of their type in the world today. Each unit provides 800 m² of heat transfer area, with a spiral body diameter over 3 metres and total height over 3.6 metres. The two units will be used in the slurry handling process of a large mining project in Southeast Asia. Designed for the characteristics of high-temperature slurry, and built through precise process calculation and precision manufacturing, they deliver efficient heat exchange under complex duties.

On the difficulties of material rolling and welding precision in manufacturing equipment this large, the Nexson technical team relied on mature processes and strict quality control to carry the units perfectly from design to delivery. Both units have now completed all testing and packing, ready for delivery to the Asian customer.

Technical strength underpins market position

Whether it is the newly signed orders for spiral plate and fully welded plate-and-shell heat exchangers or the large spiral plate units already delivered, all Nexson Group products are guaranteed by advanced technology and built on high-quality manufacturing, following strict domestic and international manufacturing standards (ASME, PED, GB) and combining advanced processes such as high-quality fully automatic welding and precision forming. This ensures reliability under complex, severe duties of high temperature, high pressure and high viscosity.

Innovation is what drives Nexson Group forward. Nexson will keep technology innovation at its core and continue to supply efficient, reliable heat exchange solutions to industries worldwide, supporting green and efficient development across all sectors.
