Introduced in 2018, the VSRT (Vertical Spiral Rib Tubeless) is described by Fulton as the first fully wetted, refractory-free vertical tubeless steam boiler. Its spiral rib heat exchanger gives a long heat-transfer path in a compact space.
The fully water-backed pressure vessel is wrapped in high-density insulation for low jacket temperatures and minimal thermal loss. Fulton lists industry-leading efficiency, high steam quality and a small footprint as the headline features.
