Bradford-White Corp Commercial Electric Brute Water Heaters, Standard Equipment Features

Commercial Electric Brute Water Heaters

Standard 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.

Temperature and Pressure Relief Valve - Factory provided ASME rated relief valve protects against excessive temperature and/or pressure buildup within the tank.

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.
