Hot Water Supply Systems

 

The "TOTAL SYSTEM" Concept - We have taken our highly efficient equipment and

Conservationist®

created a convenient package; acomplete 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 wiring 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 to1,000 gallons (Custom tanks to 10,000 gallons are available).

Other Features

ASME Temperatures and Pressure Relief Valve 125# - Tank Temperature SensorTank ThermometerIsolation Valves (Reliable Ball Valves) - Superior I-Beam Skid - 125 psi TankConstruction - CI Bronze Fitted Pump.

Options - All Bronze Circulating Pump - Sequencing Control Panel (For Multi-Boiler systems) - 150 and 160 psi TankConstruction - 11" x 15" ManholesCement and Epoxy TanksLinings.

Custom Ac-U-Temp Systems - All Ac-U-Temp Systems are built-to-order, and designed to specifically meet your specifications. Many combinations of boilers

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

Multi-Boiler Systems - High recovery systems that can meetany 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.

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 wall and double wall. Complete control packages can be factory installed for hook-up and run capability.

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.

Smith will furnish a replacement part; installation, labor, handling and local delivery extra. If the tank should leak any time during the first 5 years, under terms of the warranty, A. O.
