Options
  • UL and cUL listed conversion kits to adjust voltage and kW requirements in the field before and after installation
  • ASME 150 psi tank construction
  • International voltages - 220, 380, 400, 415, 575, and 600 volts, three phase available with Y connected elements
  • MANIFOLD KITS - for multiple tank installations. Two heaters - part #9003429205, three heaters- part #9003430205 and four heaters- part #9003431205




Features
Gold Elements - DRE models ship with the Goldenrod 24 K gold plated elements. Patented Goldenrod elements provide long life and superior scaling resistance. Low watt density means lower surface temperature to minimize scale buildup and more surface to heat water. Goldenrod elements carry a one-year warranty against failure due to lime scale build-up.

Glasslined Tank - Three sizes: 50, 80, and 119 gallon capacity. Tank interior is coated with glass specially developed by A. O. Smith® for water heater use. Tanks rated at 150 psi (1034 kPa) working pressure (ASME 150 psi). Foam insulation reduces costly heat loss.

Fusing - Protects all elements, thermostats, and internal wiring circuits against excess current flow. Meets National Electrical Code requirements that non-ASME tanks must have internal fusing when current draw exceeds 48 amps. Available as an option on Canadian built heaters.

Standard Voltages - 208, 240, and 480 V single-phase and three-phase delta. Convertible from three-phase to single-phase (in field) and vice versa. 277 V single-phase also available.

Terminal Block - Factory installed. Just bring the service to the heater and connect to block.

Controls - One temperature control (adjustable through a range of 120 to 180 ºF) and manual reset high temperature cut-off per element. Thermostat step control may be achieved by varying settings on individual temperature controls. Located behind hinged control compartment door for quick, easy access.
  • Surface mounted thermostats.
  • Simplified circuitry, color coded for ease of service.
  • Two anode rods for maximum corrosion protection.
  • Cabinet has bonderized undercoat with baked enamel finish.
  • Bottom inlet and top outlet openings.
  • Brass drain valve.
  • CSA® Certified and ASME rated T & P relief valve.
  • Single panel control box.




Testing and Certifications
Meets the standby loss requirements of the U.S. Department of Energy and current edition of AHRAE/IESNA 90.1.



Warranty
  • 3-Year Limited Tank Warranty.




Note
For Full Load Current Single Phase 277 V:
Elements available in incoloy only.
