BRYAN BOILERS
Originators of the “Flexible Water Tube” design
Guaranteed efficiency and easy
maintenance assure low cost operation
All Bryan RV Series boilers offer these operating and performance features
Guaranteed efficiency
Needing only 32" for tube removal, and on only one side
oftheboiler,theRVSeriesboileroccupiesverylittlespace
in the boiler room. This can result in considerable savings
in building costs. Pressurized firing permits minimum
sized breaching and vent.
The breakthrough in water tube boiler design that pro-
duced the RV Series provides operating efficiency so
reliable, we guarantee it to be 84% for hot water boilers
and 82% - 15 psi / 80% - 150 psi or better for steam boilers.
Multi-pass flue gas travel
The Bryan Flexible Tube
High velocity four-pass flue gas travel is obtained by a
uniquebafflingsystem.Thiscontributestomaximumfire
side heat transfer and overall high boiler efficiencies.
Bryan’s exclusive “Flexible Tube” design
eliminates the possibility of damage
from so-called “thermal
shock.” Tubes are easily
removable and replaceable,
without welding or rolling,
eliminating long, expensive
downtime should repairs
ever be required.
Thermal blend water return
Bryan’s unique “thermal blend” return blends cold or
cooler return water with warmer boiler water abridging it
todesignoperatingtemperatures.Aninjectortubedirects

Positive internal
circulation
of the heating surface is exposed to direct radiant heat,
increasing water velocities and heat transfer.
Large steam drum
The steam drum has generous water volume and steam
release area. This design, along with effective drum
internal functions, results in a stable water level and
produces extremely dry steam at all load conditions.

water tube slopes up-

damage caused by unequal temperature distribution is
especially important for heating systems, particularly
where intermittent or continuous low temperature water
returns may be encountered.
Compact design, minimum floor space
With our compact water tube design, the overall size of the
unit is less than most other types of boilers, yet maintains
a full five square feet of heating surface area per HP.
