Nexson Group has once again pushed the boundaries of industrial innovation with the delivery of the world’s largest spiral heat exchangers, designed and manufactured at our facilities in France.
These exceptional units feature:
- Heat exchange surface: More than 800 m² in one single unit
- Spiral Diameter: Close to 4 meters
- Weight: Close to 30 tons
- Construction material: high-performance duplex stainless steel
Their impressive scale and design reflect Nexson’s long-standing expertise in developing tailor-made thermal solutions for the most demanding industries.
A key contribution to the Project
The spiral heat exchangers are destined for a major mining development in the mining industry.
In this installation, the units will handle two highly challenging process streams:
- Mineral Slurry on one side
- Solvent Thickener on the other
The equipment has been specifically engineered to ensure maximum reliability, corrosion resistance, and thermal efficiency, even under extreme process conditions.
Using duplex stainless steel provides superior mechanical strength and excellent resistance to the aggressive chemical environment typical of hydrometallurgical applications.
Engineering excellence made in France
This project is a testament to Nexson Group’s commitment to innovation, precision, and performance.
From design and thermal simulation to fabrication, assembly, and testing, every stage was carried out with the highest standards of quality and safety.
“Delivering these record-breaking spiral heat exchangers is not just a technical achievement — it’s a demonstration of our capability to engineer world-class solutions for global industry leaders,” says Victor Bernardini, Engineer at Nexson Group.
By combining advanced materials, optimized flow design, and our unique spiral technology, we provide our customers with equipment that delivers exceptional energy recovery, process efficiency, and long-term durability.
Pushing the limits of performance
At Nexson Group, we take pride in driving the evolution of thermal engineering.
Projects like this highlight our ability to adapt our technology to complex industrial processes, offering bespoke solutions that improve both operational performance and environmental efficiency.
With this new step, Nexson Group continues to affirm its position as a global reference in spiral heat exchangers, proudly carrying French engineering excellence to every corner of the world.
