 Hot Water Supply Systems

Built tough with maximum efficiency

Multi-Tank Systems  - For applications with low ceiling heights

or unique installation challenges.

Optional Dual Energy Source Capability  - Ac-U-Temp storage

tanks can be specified with heat exchangers; allows winter/

summer heating boiler operation. Both, water to water, or steam

to water exchangers are available in both single and double wall.

Complete control packages can be factory installed.

Electric Back-up  - Heavy - duty electric water heater elements

and controls can be specified for up to 3,000 KW; 100% electric

back-up. Provides hot water even during natural gas curtailments.

The "TOTAL SYSTEM" Concept - We have taken our highly

efficient equipment and created a convenient package; a

complete domestic hot water system.

Simplifies Installation - The installer simply connects the flue

gas, electric supply, cold water make-up, and hot water supply

(Building return loops connect to cold water make-up.)

Eliminates Costly Field Errors - These complete hot water

systems are factory-engineered and assembled to assure

proper pipe, pump and wire sizing. Systems are pre-piped and

wired to guarantee maximum system efficiency.

Factory Tested - Each Ac-U-Temp system is hydrostatic and

fire tested before shipping from the factory.

Ac-U-Temp Storage Tanks - Each Ac-U-Temp storage tank is

especially designed with tank opening locations, that provide

maximum tank draw efficiency and eliminate any unnecessary

piping and connections. Standard Ac-U-Temp tanks are factory

jacketed and insulated (Bare tanks to be insulated by others are

also available.) The Ac-U-Tanks are factory standard with the

same superior glass lining that has set new standards for the

tank industry. Standard tank capacities range from 80 gallons

to 1,000 gallons (Custom tanks to 10,000 gallons are available).

Other Features - ASME Temperatures and Pressure Relief

Valve 125# - Tank Temperature Sensor- Tank Thermometer-

Isolation Valves (Reliable Ball Valves) - Superior I-Beam Skid

- 125 psi Tank Construction - CI Bronze Fitted Pump.

Options - All Bronze Circulating Pump - Sequencing Control

Panel (For Multi-Boiler systems) - 150 and 160 psi Tank

Construction - 11" x 15" Manholes- Cement and Epoxy Tanks

Linings.

Custom Ac-U-Temp Systems - All Ac-U-Temp Systems are

Built to order, and can be precisely designed to specifically meet

your specifications. Many combinations of boilers and tanks are

available. Consult your local A.O. Smith Representative for

factory assistance.

Multi-Boiler Systems - High recovery systems that can meet

any hot water demand. Systems can be designed to provide 50

to 100% back-up. Boilers can be on & off fired, or sequenced to

meet changing system demands.  Sequenced multi-boiler

systems that employ relatively small storage tanks are ideal for

applications with constant, yet fluctuating hot water demands.
