HP Steam Boilers - Indoor Atmospheric / Natural Gas Fired

Indoor High Pressure Steam Boiler - Atmospheric / Natural Gas FiredRite Atmospheric Natural Gas Fired High Pressure Steam Boilers have been providing our valued customers with high quality steam safely and reliably for over forty years. From autoclaves to medical centers food processing to textiles, hospitals to industrial process manufacturing - these heavy duty watertube steamers are available in 16 different models, ranging from 398 – 10,456 MBH input (9.5 - 250 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 our other standard features: Rite’s floating heads that eliminate pressure vessel cracks and broken welds caused by thermal stress cycling (backed by our 25 Year Thermal Shock Warranty), 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 Boiler are an excellent choice when: Low NOx emissions are not required, natural gas will be the only fuel used, the installation is indoors (See our line of weatherproof models for outdoor applications), and when lower combustion efficiencies at less the full firing rate are acceptable.

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