DSE

  • 90 kW input
  • 65 – 120 gallon capacity
  • Single or three phase
  • With new advanced electronic control, provides + or – 1ºF temperature control

Note: The available range is smaller due to Gulf Mark. The range is available from the DSE-65A up to and including the DSE-120A.

  • A. O. Smith’s new proprietary electronic water heater control provides precise + or – 1° temperature control that is ideal for industrial and food service applications where exact temperatures are needed.
  • The Operating Set Point is adjustable from 90°F/42°C to 190°F/88°C. The factory setting is 120°F/49°C.
  • Approved for 180°F/82°C sanitizing applications.
  • Animated icons display detailed operational and diagnostic information.
  • Fault or alert messages appear if an operational issue occurs.
  • Each element is constantly monitored and current on/off state is displayed, any element failure is reported and its exact location is shown, eliminates a need for field testing of elements.
  • Factory standard on board low water cutoff uses a remote electric immersion type probe to prevent energizing of the elements in the event of low water condition and eliminates accidental dry firing.
  • 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.
  • Control system automatically lowers the operating set point by a user defined value during setback periods. Seven-day clock may be programmed for night set back and or weekend shutdown to reduce operating cost and save energy.
  • BACnet or Modbus compatible with optional ICC Gateway.
  • The DSE models use a unique combination of a conventional sacrificial anode and an adaptive powered anode. The powered anode is self-adjusting to water conditions, does not require maintenance 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 conventional commercial electric water heaters.
  • Heavy-duty elements provide excellent protection against oxidation and scaling. Input ranges from 3kW to 90kW available (see accompanying chart). Rugged, industrial grade, elements.
  • All models meet or exceed the thermal efficiency and/or standby loss requirements of the U. S. Department of Energy and current edition ASHRAE/IES 90.1.
  • A.O. Smith’s PermaGlas® coating provides truly superior protection against corrosion and is permanently bonded to all inner tank surfaces at 1600°F.
  • ASME tank construction 160 psi working pressure
  • Standard voltages 208, 240 and 480 volt single and three phase. All 208 and 240 volt at 24kW 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 powered by fused transformer.
  • Magnetic contracters. Heavy-duty UL rated for 100,000 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-codes for ease of service
  • Hinged control compartment door
  • CSA certified and ASME rated T&P relief valve
