Rite Power Burner Fired Low Pressure Steam Boilers have been providing their valued customers with high quality steam safely and reliably for over forty years. From autoclaves to humidifiers, bakeries to breweries – these heavy duty watertube steamers are available in 47 different models, ranging from 480 – 12,499 MBH input (11 – 300 Boiler Horsepower) for the widest selection possible.

So simple to maintain and operate, Rite Steam Boilers feature complete waterside access so that virtually all scale and mud deposits can be seen and mechanically cleaned during a single scheduled maintenance shutdown. The result – Better fuel-to-steam efficiency and lower operating cost over the life of your boiler investment. Consider a few of their other standard features: Rite’s floating heads that eliminate pressure vessel cracks and broken welds caused by thermal stress cycling, Rite’s “superheated” drying tubes that regularly boost steam quality at the nozzle into the 99%+ range, Rite’s bolted/gasketed headplates that eliminate any possibility of hydraulic explosion in the event that safety devices fail – and you have a better boiler by design.


Rite atmospheric gas fired low pressure steam boilers are the boiler of choice for breweries, bakeries, distilleries and building heat throughout North America.

Some of their most important features include: A broad range of sizes – from 3 to 300 horsepower. Lower water content steams faster and uses less fuel than other designs. Extra tubes in the convective section deliver dry 99% high quality steam. Whisper quiet operation (between 20-30 dBA at 3 feet). Burner has no moving parts, and can be permanently set in a few minutes with a screwdriver and a gas pressure gauge. Flame safeguard controls are microprocessor based and can support a keyboard display module. Header box expansion joint allows free movement of tubes. Heavy duty steel base and construction throughout. Document holder on side of boiler (with complete O & M Manual). Headplates are hinged for easy access and in- sulated to improve efficiency. 100% access to waterside surfaces = maintainable efficiency for the life of the boiler.


Rite Atmospheric Boilers are an excellent choice when: Low NOx emissions are not required, natural gas will be the only fuel used, the installation is indoors, and when lower combustion efficiencies at less than full firing rate are acceptable.

Atmospheric burners are far less expensive than power burners, so when the above criteria is met, then Atmospherics are a strong economical alternative to Rite’s outstanding line of power burner fired steam boilers. Other factors favoring At- mospherics are: Extremely low electrical power consumption (no energy hogging fan motors), Rapid start-up on demand (No pre-purge blower fan), Lighter weight, Lower height, and Whisper-quiet burner operation.
