tandard Equipment Features:

Energy-Saving Performance - A heavy blanket of high-

density fiberglass insulation is used to meet the demanding

ASHRAE 90.1b current standard for minimizing heat loss.

This requirement, allowing a maximum 4 watts per square

foot of tank surface energy loss, offers big savings and

operating efficiency.

Magnetic Contactors with Immersion Thermostats - 120

volt control circuit with built in transformer. Elements are

thermostatically controlled in 54kW (max) increments.

Low Watt Density Incoloy Elements - Incoloy elements

are used by Bradford White because of their many superior

characteristics to copper-sheathed elements in rigorous

water heating applications. This tough alloy successfully

resists the effects of prolonged high operating

temperatures, hard water, acids, corrosion, and thermal

shock. Their nominally higher initial cost is more than offset

by much longer life expectancies and reduced service and

replacement labor costs. Incoloy elements are designed to

“burn in air” to prevent failures caused by water void.

Internal Fusing - All elements and circuits are fused in 48

amp increments, providing complete electrical protection.

Cartridge type fuses are rated at 200,000 ampere

interrupting capacity.

Glass-Lined Tank - Vitreous glass is applied to the inside

surface of the steel tank and fired to 1600°F. (All models are

constructed in accordance with the ASME code and

approved for 125 PSI working pressure.)

Magnesium Tank Saver - Provides anodic protection

against corrosion of the tank due to electrolysis.

Galvanized Jacket - The heavy 16-gauge steel jacket is

galvanized on both sides and beautifully finished in durable

acrylic enamel. This combines attractive appearance with

maximum protection.

Full-Length Hinged Door with Key Lock - Quality requires

full-length hinged doors for ease of inspection and

maintenance. Keyed door lock provides additional safety

and security at no extra charge.

Terminal Block Connections - Easy and safe wiring

connections are made possible by factory installed

terminal blocks.

180°F Temperature Operation - Every Electric Brute

Heater is approved for 180°F operation for sanitizing and

other high-temperature requirements.

Hand Hole Cleanout - Provides easy access to the heater

interior for inspection and cleaning.

UL Listed - All models are listed by Underwriters

Laboratories, Inc. as commercial electric water heaters.

This assures competent design and proper testing.

Three-Year Limited Warranty - Provides warranty

protection against tank failure resulting from defects in

material and workmanship.

Channel iron skid base.

Optional Equipment Features:

Low Water Cut Off - Prevents energizing of the heater

when not filled with water or upon low water condition.

Pilot Lights - Monitor on/off cycle for each contactor.

Manual Limiting Switches - With indicating lights –

permits manual limitation of heating input by switching off

current to each contactor.

Solid State Modulating Control (Electronic Step

Controller) -

Modulates power input and balances load to

demand. Contactors are staged automatically and

sequentially to equalize element usage. Unit reprograms to

“off” position on power failure.

Alarm Bell - Warns of various control failures.

Shunt Trip Disconnect† - Provides maximum protection by

interrupting all power to the system in the event of a control

sensed malfunction or overcurrent.

Low or High Pressure Switch - Turns off control circuit

when water pressure drops below a set minimum, or above

a set maximum.

Time Clock† - To control off/on cycles of the heater as

programmed by the owner or electric utility requirements.

(7 day or 24 hour).

Safety Door Interlock - Prevents opening of access door

while heater is energized.

Temperature and Pressure Gauges - Jacket mounted for

convenient viewing.

Man Hole - Provides means to easily remove sediment

from the heater; optional on 250 gallon and larger.

Working pressure - 150 PSI ASME construction.

†Separate mounting.
