The renowned Fulton boiler group introduces the first true New Generation steam boiler in over 50 years!

In 1949, Fulton pioneered the vertical tubeless design, which quickly became the industry standard for industrial steam boilers.  Since that time no one has been able to improve upon Fulton's original design with the  Fulton J-Series holding much of the Australian market share.  The J-series simple, compact design and robust construction from top quality materials made them ideal for arduous applications in a wide range of industries and for numerous industrial, pharmaceutical, medical, food and beverage steam production needs. 


Now Fulton is raising the bar with the new technology VSRT (Vertical Spiral Rib Tubeless) boiler. The world's first fully wetted, refractory-free vertical tubeless boiler which has immediately been recognised as the new standard for industrial steam boiler design. 

VSRT boilers have employed 'PURE Optimized' design technology and are built to last as a reliable source of steam.  They are extremely energy efficient, environmentally clean, and in standard trim are equipped with the best possible controls and technology to ensure cost savings and operator peace of mind for years to come.

The design of the Fulton J-Series boiler provides increased thermal efficiency, with reduced flue gas and casing temperatures.  It is easy to service and maintain, with good access for cleaning and inspection of internal surfaces.
