The LX Gas/Low NOX Series is offered with boiler models ranging from 50 to 300 hp.  The industrial boilers use natural gas or propane and are available in a range of steam pressure options (300, 170 or 15 MAWP). The compact size allows most models to fit through an industrial 7’ doorway. Low NOX ratings are as low as 9 ppm, depending on model. This meets or exceeds current and proposed regulations for nitrogen oxide emissions levels. Hot water boilers are also available depending on models. The design consists of vertical water tubes in a rectangular array, encased in a castable refractory with only the tubes exposed to flame and/or combustion gases. The upper header is attached to the lower header only by the tubes. As the tubes expand and contract, the headers float up and down accordingly. The floating header concept allows for even thermal expansion of the tubes, therefore reducing stress points within the boiler.
