Dura-Power™ commercial electric water heaters are built to the same high-quality
standards as our gas models. These are the largest commercial electric's we
manufacture. Ideal for use as recovery heaters for all types of large commercial and
industrial applications or for large process potable hot water requirements. They
can be customized to meet any special application with the large selection of
available options.
Advanced Electronic Control (All Models
150 kW and Down)
A. O. Smith’s new propriety electronic water
heater control, provides precise + or - 1ºF
temperature control, that is ideal for industrial
and food service applications where exact
temperatures of hot water are needed.
 Plain Text – Animated icons display
detailed operational and diagnostic
information. Fault or Alert messages
appear if an operational issue occurs.
 Low Water Cut Off – Factory standard on
board low water cut-off uses a remote
electronic immersion type probe to
prevent energizing of the elements in the
event of low water condition and
eliminates accidental dry firing.
 Progressive Modulating (only available on
units 150 kW or less) – Sizes the input of
available elements to match current load
conditions. Rotates and lead lags element
loads to provide long life and equal wear.
 Economy Mode Operation (only available
on units 150 kW or less) – Control system
automatically lowers the operating set
point by a programmed value during user
defined time periods. Seven-day clock
may be programmed for night set back
and or weekend shutdown to reduce
operating cost and save money.
 iCOMM™ Compatible – Units can be
monitored from remote locations. Call
1.888.WATER02 for more information.
Note: Up to 150 kW only. Units above 150
kW use analog controls.
Solid State Modulating Step Control
(All Models 180 kW and up)
 Solid state electronic control device that
modulates input to match load through
progressive sequencing of steps (up to 20
steps with maximum of one per contactor).
Glasslined Tank
 Tank interior is coated with glass
specially developed for use in
water heaters. Tanks rated at
125 psi working pressure; 150
psi or 160 psi working pressure
is optional. Vermin proof fiber
glass insulation reduces costly
heat loss. Constructed to Section
IV of ASME code, and UL
standards. Tanks have channel
skid base. A 4” x 6” handhole is
furnished on 500, 600 and 700-
gallon models; 11” x 15”
manhole is furnished on
800-gallon and larger sizes.
Incoloy Immersion Heaters
 Heavy-duty medium watt density
elements (three immersion heater) have
incoloy sheathing: provide excellent
protection against oxidation and scaling.
The input ranges from 15kW to 3000kW.
Fusing
 Control and power circuit fusing to
meet N.E.C.
Compliance
 Meets the standby loss requirements of
the U.S. Department of Energy and
current edition of ASHRAE/IESNA 90.1.
Magnetic Contactor(s)
 Heavy duty UL rated for 100,000 cycles.
Other Standard Features
 Color-coded circuitry for easier servicing
 Anode rods for maximum corrosion
protection
 Standard voltages include 208, 240, 480,
600 volt single or three-phase.
 For other voltages consult factory.
 Factory-installed terminal block(s)
 Cabinet has baked enamel finish
 Prewired element terminal leads
 Temperature and pressure relief valve
 2” dial temperature gauge
Optional Dual-Energy Source Capability
 Provides emergency back up energy
source or winter/summer boiler operation.
Can be specified with optional water to
water or steam to water heat exchangers.
Both single and double wall heat
exchangers are available. Complete
control packages can be factory-installed
for hook up and run capability.
