In the year that sees them celebrate 50 years of UK manufacturing, Fulton is to launch a heat transfer solution, claiming that the all-new SRT Series is the most radical change to vertical steam boiler design since the company pioneered the vertical tubeless boiler in 1949!

By adopting a systems engineering approach to design and using its own ‘PURE’ technology, Fulton’s SRT Series challenges the heat transfer and mechanical design principles of traditional vertical steam boilers.

With 30+ worldwide patents pending, the boiler’s spiral-rib tubeless design is a world first and creates a compact boiler with the industry’s smallest footprint. In fact, compared to equivalent 30hp Fulton J Series models, the SRT is an impressive 40% smaller.

Using in-house modelling with CFD and finite element analysis, the SRT’s ‘PURE Optimised’ design makes it durable and reliable; and with up to 6:1 turndown and a fully-modulating burner, the SRT also boasts industry-leading performance with an 84.5% Gross (93.5% Net) thermal efficiency and 99.5% steam quality from a fully-water-backed design with no refractory.

The SRT complies with anticipated EU regulations, with its combustion technology being reconfigured and the mesh burner and furnace designed as a single component, resulting in NOx emissions of less than 40mg/kWh.
