A nearly 30-tonne giant enters service in the heat exchanger industry.
Nexson Group has pushed past the technical ceiling for spiral plate heat exchangers once again — delivering the world’s largest Type 1 liquid/liquid spiral plate heat exchanger. This “industrial giant” was designed and built entirely by Nexson Group, and it is not only heavy: it breaks through the industry’s ceiling outright.
How extreme is this machine? A few numbers give a direct sense of it:
Heat transfer area: over 800 m² in a single unit.
Spiral body diameter: close to 4 metres — roughly the height of one and a half storeys of an apartment building.
Weight: nearly 30 tonnes — about the combined weight of 20 family cars.
Material: high-performance duplex stainless steel, resisting abrasion and corrosion for a long service life.
And it is not large for the sake of being large — it solves a real need in mining.
This unit was purpose-built by Nexson for a mining process: within the mineral extraction flow it performs the dual task of cooling mineral slurry while heating solvent, doubling heat transfer efficiency and matching the core heat exchange requirement of the mining application precisely.
Spiral plate heat exchangers — built for media that block easily
1. Higher heat transfer performance: the spiral channel makes the material turbulent even at low flow velocity, and the fully counter-current structure delivers a high heat transfer coefficient.
2. Longer operating cycles: the single-channel structure has a self-cleaning capability, so fluid in the channel is less prone to scaling and blockage, giving longer runs between stops.
3. Lower maintenance cost: removable end covers and lifting arms on both hot and cold sides make inspection and cleaning straightforward, cutting both downtime and labour cost.
This is Nexson engineering showing what it can do
The project demonstrates Nexson Group’s hard capability in full: from thermodynamic design and manufacturing through to final inspection and dispatch, everything was executed to the highest standards in the industry, with the aim of delivering “robust + reliable + efficient” solutions for the most severe industrial environments. From pushing the limits of thermal and mechanical performance to turning the essence of Nexson technology into practical equipment, this spiral plate heat exchanger is not only a win for the Nexson team but a living example of industrial innovation “going where it matters”.
Nexson Group’s professional engineers are committed to making “large equipment” precise and specialised, and will continue to provide one-stop customised solutions for customers across industries.
