VSRT Vertical Spiral Rib Tubeless Steam Boiler.

Size Range: (0.5t/h to 4t/h)

Fulton raises the standard with the VSRT (Vertical Spiral Rib Tubeless) boiler, the world’s first fully wetted, refractory-free vertical tubeless boiler, setting a new benchmark for industrial steam boiler design.

A Revolution in Steam Boiler Design

Fulton’s patent-pending spiral rib heat exchanger achieves industry-leading heat transfer rates. The unique spiral design provides a long heat transfer path, optimised for maximum heat transfer in a compact space.

The VSRT features a fully water-backed pressure vessel wrapped in high-density insulation, minimising thermal losses and maintaining low jacket temperatures.

Its ultra-compact vertical design ensures the smallest footprint in the industry.

Refractory-free design.
