All Bryan RW Series boilers offer these operating and performance features
Guaranteed efficiency
The breakthrough in water tube boiler design that pro-
duced the RW 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.
The Bryan Flexible Tube
Bryan’s exclusive “Flexible Tube” design eliminates the
possibility of damage from so-called “thermal shock.”
Tubes are easily removable and re-
placeable, without welding or roll-
ing, eliminating long, expen-
sive downtime should repairs
ever be required.
Water cooled furnace
The configuration of the wa-
ter tubes provides a water
cooled combustion chamber.
A high percentage of the heat-
ing surface is exposed to di-
rect 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.
Accessibility of furnace and tube area
Inner panel provides easy and complete access to boiler
tube area. All panels are heavily insulated and sealed to
boiler frame.
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.
Water Boiler
Combination thermometer and altitude
gauge, ASME Code rated boiler relief
valve, water temperature control (240°F
max std.), high limit control, probe
LWCO.
Steam Boiler
Steam pressure gauge, steam pres-
sure control, combination low water
cutoff and pump control, auxiliary low
water cutoff, high limit pressure con-
trol, ASME-rated safety valve, water
glass set.
Straight gas fired unit
Electronic combustion safety control,
automatic operating gas valve, safety
gas valve, pilot solenoid valve, pilot
ignition assembly, main manual gas
shut-off valve, pilot cock, pilot and
main gas pressure regulators, air safety
switch, control panel, all controls in-
stalled and wired. All units are stan-
dard with full modulation with proven
Needing only 32" for tube removal, on each side of the
boiler, the RW Series boiler occupies very little space in the
boiler room. This can result in considerable savings in
building costs. Pressurized firing permits minimum sized
breaching and vent.
Multi-pass flue gas travel
High velocity five-pass flue gas travel is obtained by a
unique baffling system. This contributes to maximum fire
side heat transfer and overall high boiler efficiencies.
Thermal blend water return
Bryan’s unique “thermal blend” return blends cold or
cooler return water with warmer boiler water abridging it
to design operating temperatures. The “mixed” water flow
keeps the lower header and heating surfaces at a tempera-
ture above possible condensing conditions. This reduces
the possibility of “cold spots” and damage from corrosive
condensation.
Positive internal
circulation
Each pass of the Bryan
water tube slopes up-
ward. This configuration,
along with the large vol-
ume downcomer water
legs, provides the ex-
tremely rapid natural
thermal internal circula-
tion, promoting both high
efficiency of heat trans-
fer and uniform tempera-
ture throughout the boiler. Elimi-
nating stress damage caused by unequal
temperature distribution is especially important for heat-
ing systems, particularly where intermittent or continuous
low temperature water returns may be encountered.
