Heavy Duty Electric Commercial Water Heaters
Available in 50, 85 and 120 Gallon Tank-Type Models
6 KW thru 81 KW
Rheem-Ruud Electric Commercial Water Heaters are suitable for general commercial
hot water applications and are also ideal for point-of-use installations. A single unit can
be used as a booster heater to satisfy the hot water requirements of commercial dish-
washers. A single temperature storage unit, when installed with a mixing valve, will
supply two temperatures in food service establishments.
Construction Features:
• System Sentinel –
immersion thermostat models employ
an element diagnostic panel, utilizing
light emitting diodes (L.E.D.), corre-
sponding to the number and location
of each heating element. This system
monitors the on-off function of the
electric heating elements.
• Long life ASME tank design –
proprietary steel formulation with
high temperature porcelain enamel to
maximize corrosion resistance result-
ing in a superior tank design.
• LIFEGUARD heating elements –
separate screw-in type elements fea-
ture a stainless steel outer sheath of
INCO-LOY 840, surrounding a
Nichrome wire filament, to resist water
chemical corrosion and burn-out even
in air or sediment…for long element
life and long life performance.
Elements are directly immersed in the
water for maximum recovery efficiency
(98%) and are easily changed by sim-
ply screwing new ones into the tank.
LIFEGU
ARD elements feature a three
(3) year limited warranty.
• Full port, full flow brass drain
valve
• Minimal heat loss design –
85% of the tank surface area on all
Rheem-Ruud Commercial Electric
products are insulated with 3" of rigid
polyurethane foam insulation providing
superior insulating qualities. Unlike
other designs, Rheem-Ruud
Commercial Electrics can achieve 85%
because of the unique compact layout
of the heating elements. This results
in heat losses less than the energy
used by a 100 watt light bulb during
a 48 hour standby period!
Certifications and Ratings:
• Efficiency –
in accordance with ANSI test procedures, these models tested
below the maximum allowable standby loss levels of ASHRAE Standard
90.1b-2001 (Part of the Federally mandated Energy Policy Act (EPact)).
Also exceeds energy efficiency codes of all states including California Energy
Commission (CEC).
• Safety and construction –
These products are design certified by Underwriters
Laboratories (UL) to meet UL standard 1453 as electric booster and commercial
storage tank water heaters. All models are North Carolina code compliant.
CERTIFIED FOR A
150 PSI MAXIMUM WORKING PRESSURE
(160 PSI FOR ASME MODELS).
• Optional construction –
ASME construction is available on immersion
thermostat models.
