Vertical Firetube

The original vertical tubeless down-fired design have remained a compact trouble-free boiler for over 60 years, supplying steam and hot water to virtually every type of industry imaginable. Vertical tubeless boilers offer efficiencies up to 84%, and can be ordered with oil and/or gas capabilities with low emissions burners (gas only).


TRIAD
(OWNED BY SUPERIOR BOILER WORKS) – TRIAD offers both Low Pressure and High Pressure packaged steam and hot water boilers. These are ready-to-install systems featuring a perfectly matched powerful and efficient burner/boiler combination ideal for Space Heat and Industrial Process applications. See the links to the right for more information on the various sizes. All steam boiler controls and secondary plumbing are in place and pre wired and most TRIAD vessels are designed to easily fit through a three foot wide doorway resulting in a very quick start-up. TRIAD Steam Boilers heat very rapidly and thus create dry steam quickly.

 

PRECISION – The Precision Model “FPS” Vertical Fire Tube Steam Boiler features the traditional Fire Tube design in the vertical configuration with an under-fired power burner. In addition to the simplicity of the 4-piece design, the Model “FPS” includes many advantages over other vertical configured boilers such as larger water volume and steam chest which reduce cycling and improve overall efficiency, easier sludge cleanout, standard “off-the-shelf” burners, and the proven Fire Tube reliability. An integral feedwater preheater eliminates “cold water shock” problems characteristic of some fixed tubesheet designs.
