Optional Equipment and Construction

Optional Equipment and Construction

 N/A Goldenrod® Elements - All DSE models are available with the patented Goldenrod® 24K gold plated elements. Goldenrod® Elements provide long-life and five times the scaling resistance of standard incoloy elements. Goldenrod® Elements carry a three-year warranty against failure due to scale.

Stainless Steel Tank - Available for deionized water. Add a D to the end of the model prefix for use with deionized water. For example a DSE5 would become a DSED5.

Please note: Stainless Steel units are deionized water heating applications only! DSED models are not approved or certified for domestic potable water heating applications. To maintain warranty for domestic potable hot water heating applications. To maintain warranty for domestic potable hot water heating applications use on the DSE glass-lined models.

150 or 160 PSI Working Pressure - Available when required. Must be specified at time of order.

Hand hole Cleanout - 4" x 6" size.

Combination Temperature/Pressure Gauge - Dial type combination gauge (shipped loose).

Control Options

Control Options

 N/A Override Switches - A simple form of load control allows all or part of unit input to be controlled manually. Up to one override switch per contactor is available.

Indicating/Pilot Lights - For indicating element operation and/or switch closure. Up to one indicating light available for each switch and/or contactor is available.

Modulating Control - The first element on is the first element off. Not available on single element, single contactor units.

Pressure Limit Switches - Both high and low pressure limit switches available.

Power Circuit Fusing - Sub-divides internal circuitry with maximum of 60 amp fuses. Supplied as standard when required by NEC and UL.

Alarm Horn - Horns may be furnished to warn of any condition in the heater for which sensors have been specified.

Manifold Kits
  • Two Heaters - 9003429205
  • Three Heaters - 9003430205
  • Four Heaters - 9003431205
Optional International Voltages - 380, 415, 575 and 600 volts three-phase available with Y connected elements.

Features

Features

 N/A Advanced Electronic Control
A.O. Smith’s® new proprietary electronic water heater control, provides precise + or – 1 ºF temperature control, that is ideal for industrial and food service applications where exact temperatures of hot water are needed.

Plain English Text - Animated icons display detailed operational and diagnostic information. Fault or Alert messages appear if an operational issue occurs.

Element Sensing - Each element is constantly monitored and current on/off state is displayed, any element failure is reported and it’s exact location is shown, eliminates any need for field testing of elements.

Low Water Cut Off - Factory standard on board low water cutoff 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.

Sequencing - Units with multiple element contactors are sequenced on with one-second delay between stages. Prevents high amp electrical loads from hitting the electric system all at once and provides a smoother operating unit. Adjustable modulating mode is optional see options.

Economy Mode Operation - 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 energy.

iCOMM™ Compatible

Powered Anode
The DSE models use a unique combination of a conventional magnesium anode and a European style power anode. The powered anode is self-adjusting to water conditions, does not require maintenance unless damaged, and provides longer-lasting tank protection in hard to reach areas. This multi-anode system provides superior anodic protection to hidden surfaces of the tank not protected in convention commercial electric water heaters.

Incoloy Immersion Heaters - Heavy-duty medium watt density elements have incoloy sheathing and prewired leads: provides excellent protection against oxidation and scaling. Input ranges from 3 kW to 90 kW available.

Glass Lined Tank - A. O. Smith®’s PermaGlas® coating provides truly superior protection against corrosion and is permanently bonded to all inner tank surfaces at 1600 ºF.

Standard Voltages - 208, 240 and 480 volt single and three phase. Single phase 208 and 240 are convertible to three phase. All 208 and 240 volt at 24 kW and below are supplied phase convertible (single to three and vice versa). 277 volt single phase also available. Consult factory for 120 volt power circuit availability.

Terminal Block - To accept copper or aluminum leads on units with more than one contactor.

120 Volt Control Circuit - 120 volt control circuit powered by fused transformer.

Magnetic Contactors - Heavy-duty UL rated for 100000 cycles.

Power Circuit Fusing (120 Amp Current Draw and Above) - Meets National Electric Code and UL requirements that water heaters must have internal fusing when current draw exceeds 120 amps.

Simplified Circuitry, Color-coded for Ease Of Service

Brass Drain Valve

Hinged Control Compartment Door

Designed for use as a recovery heater having its own storage tank or booster for supplying sanitizing rinse water for dishwashing.
