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 de-
signed 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 ener-
gized 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 0.430؆ 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.
Bryan Series BE 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.
