ELECTRIC WATER HEATERS
CUSTOM Xi™ SERIES
HEAVY DUTY COMMERCIAL ELECTRIC WATER HEATERS
ADVANCED ELECTRONIC CONTROL
•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.
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 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.
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.
NIGHT SETBACK OPERATION
•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.
BUILDING MANAGEMENT SYSTEM
•BACnet or Modbus compatible with optional ICC Gateway.
•Call 1.888.WATER02 for more information.
POWERED ANODE
•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.
INCOLOY IMMERSION 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.
FOAM INSULATED
•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.
GLASSLINED TANK
•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
THREE YEAR LIMITED WARRANTY
•For complete warranty information consult written warranty.
