Nexson Group continues to push the boundaries of industrial innovation with the successful delivery of 22 custom-engineered Super Duplex spiral heat exchangers. Specifically designed for the demanding phosphate mining industry, these high-performance units illustrate our capacity to meet the most complex thermal and material challenges in the sector.
The Critical Challenge of Cooling Phosphoric Acid with Seawater
In phosphate processing, cooling phosphoric acid using seawater is one of the most severe and demanding applications for thermal equipment. The combination of a highly corrosive fluid on one side and aggressive seawater on the other makes material selection absolutely vital to ensure the safety, durability, and profitability of the installations. Faced with such an environment, standard solutions quickly prove insufficient and risky.
The Technological Alliance of Super Duplex and Spiral Profile
To overcome this dual challenge of extreme corrosion and fouling, Nexson Group’s engineers developed a perfectly optimized, custom solution. By utilizing premium Super Duplex stainless steel, the equipment benefits from exceptional resistance to pitting and crevice corrosion in chlorinated and acidic environments.
Furthermore, the inherent architecture of Nexson Spiral heat exchangers provides remarkable resistance to the phenomenon of fouling. The single, curving channel creates a continuous self-cleaning effect, thereby maintaining optimal thermal performance over time and significantly reducing both maintenance frequency and operational costs.
