For commercial, institutional and industrial applications

Electric Element Bundle

Each element
replaceable with
hand tools. Incoloy
sheathed, 75
watts/sq in

150 lb ANSI flange

Spacing disc for
support and
proper circulation
around individual
elements

Bryan Series BH electric hot water** or steam boilers are
compact, completely packaged and wired units with automatic
controls featuring long life Incoloy sheathed elements. Applica­tions include hot water heating, steam heating, process heating,
and supplemental heat for heat pump type equipment.

All Bryan Boilers are built in accordance with the requirements
of the ASME boiler and pressure vessel code and are UL listed.
Water boilers are 150 psig MAWP and steam boilers either 15
psig or 150 psig. Higher pressures are available.

Removable
threaded fittings
for ease of
individual element
replacement

Efficiency

Bryan Electric Boilers are nearly 95% efficient at all load levels.
Varying loads do not effect the efficiency since the resistive type
heating elements are immersed and designed to heat the water
directly. With a modulating step control only the elements that
are required to heat the water to the desired temperature/
pressure will be energized in order to encourage a balanced load
during operation.

Replaceable Hairpins

Each element hairpin is field replaceable with no welding,
soldering, or brazing required. Each hairpin, as standard for all
Bryan Electric Boilers, is Incoloy sheathed and industrial size

0.430ⴖ diameter. Elements are designed for 75 watts/sq. inch
for long life (optional 50 W/D available). Elements are individually
installed in a standard ANSI 150 lb. blind flange.

Steam Disengaging Area

Steam release area is near the middle of the horizontal vessel for
maximum steam disengaging area for dry steam and stable
water level.

Water Boiler Design

Vessel is designed for proper circulation around individual
elements to maximize heat transfer. High velocities, i.e. heat
pump applications, are handled with very little pressure drop
when using a horizontal tank for the pressure vessel. Supply and
return nozzle sizes can be made larger to accommodate the
flow requirements. Pressure drop is minimal through the boiler
and no dangers are involved with low flow conditions.
