For over 50 years, Fulton boilers, with the original vertical tubeless down-fired
design, have remained a compact trouble-free boiler supplying steam
and hot water to virtually every type of industry imaginable.
Built and stamped to the ASME Code, Fulton 4-60 HP vertical tubeless steam
boilers are CSA Approved, UL Approved packaged boilers, and are manufactured to
CSD-1 Code, with state of the art microprocessor burner controls.
Standard Fulton vertical tubeless steam boilers offer 80%+ efficiency,
while a higher efficiency model is available in 10, 15, 20, 30, 50, and 60 HP.
Fulton standard vertical tubeless boilers can be ordered with combination oil
and gas capabilities or be converted at any time simply and economically. Higher
efficiency ICX models are available with gas fired burners only. All Fulton
boilers are completely trimmed packaged boilers. No additional fuel train items
or electrical wiring is needed.
Fulton's ICX boiler's stack temperatures can be from 100 to 150F below other
two pass designs and have cut fuel bills in half!

boilers Brochure for more information.
