A.O.Smith Commercial Electric Water Heaters : DVE Series
The DVE Series are Commercial Electric Floor Standing Water Heaters. Designed for use as a recovery heater having its own storage tank. These water heaters are manufactured in USA and are UL Certified.
Available Capacities
- 72 to 105 Gallon capacity.
- Three Phase
- 9 to 53 kW
Technical Features:
Heating Element
Heavy-duty medium watt density elements (three/immersion heater) have Incoloy Sheathing: provide excellent protection against oxidation and scaling. \
Thermostats
Surface mounted thermostats. Electronic controls allow accurate temperature setting from 32° to 88°C and have communication for BMS monitoring and remote on/off contact.
Display
Animated Icons display detailed Operational and Diagnostic information. Fault or alert messages appear if an operational issue occurs
Monitoring of Elements
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.
Low Water Cut off
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.
Prevents High Amp Electrical Loads
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
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.
Pressure Rating
Tanks rated at 150 PSI (1034 kPa) working pressure
Terminal Block
Terminal block is factory installed. Just bring the electrical service to the heater and connect to block.
Control Box
Single panel control box is provided.
Fuses
Fuses protect all elements, thermostats, and internal wiring circuits against excess current flow. Meets National Electrical Code requirements.
Ease of Service
Simplified circuitry, color coded for ease of service
Cabinet
Cabinet has bonderized undercoat with baked enamel finish. Bottom inlet and top outlet openings.
Internal Coating
Glass lined tank. Two sizes: 80 and 119 Gallon capacity. Tank interior is coated with glass specially developed by A. O. Smith for water heater use.
Drain Valve
Brass drain valve.
Anode Rods
Two anode rods for maximum corrosion protection.
Temperature and Pressure Safety Relief Valve
CSA certified and ASME rated T&P relief valve.
Foam Insulation
Foam insulation reduces costly heat loss.
