6KW - 54KW Electric Booster
Commercial Water Heaters
10 Gallon Capacity
ꢀ
6KW thru 54KW
Rheem-Ruud Electric Booster Water Heaters are specifically designed to fit under
counters and deliver 180°F sanitizing rinse water for all stationary rack and convey-
or type commercial dishwashers. They will raise preheated or cold water to 180°F
rinse temperature for compliance with UL Sanitation (NSF5) and all Federal, State,
County and Local Health Department Sanitation Codes. In addition, these models
can be used as circulating tank commercial electric water heaters for gravity or
pump circulation to an auxiliary storage tank.

Construction Features:
•
System Sentinel –
•
Long life heating elements –
separate screw-in type elements
feature a Nichrome wire filament,
embedded in magnesium oxide
sealed in a copper tube to resist
water chemical corrosion…for long
element life and a long life perform-
ance. Elements are directly immersed
in the water for maximum recovery
efficiency (98%) and are easily
changed by simply screwing new
ones into the tank.
Immersion
Thermostat(s)
all electric booster models employ an
element diagnostic panel, utilizing
light emitting diodes (L.E.D.), corre-
sponding to the number and location
of each heating element. L.E.D.’s are
energized when the electric elements
are operating. An unlit L.E.D.
pinpoints the exact location of a
non-functioning element, making
element operation diagnosis simple
and positive.

•
Long life tank design –
proprietary steel formulation with a
unique coat of high temperature
porcelain enamel to maximize
corrosion resistance resulting in a
superior tank design.
Certifications and Ratings:
• Efficiency – these models meet or exceed thermal efficiency and standby loss
requirements of current ASHRAE standards. (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 UL Sanitation (NSF5) and North
Carolina Code compliant.
CERTIFIED FOR A 150 PSI MAXIMUM WORKING PRESSURE.

Other Features:
• Integral fusing – all models have integral
• 120 volt control circuit – all units are furnished
with a fused 120 volt control circuit. All controls
(thermostats, high temperature limit, etc.) are
operated off of this basic 120 volt control circuit.
This circuit is created by an internal multi-tap
transformer of unique design that has four
(4) taps for the primary voltages, 208, 240,
277 and 480.
fusing for each element.
• Anode rods – two (2) magnesium anodes
are installed in each tank for maximum
corrosion resistance.
• Temperature and pressure relief valve –
AGA/ASME rated and factory installed.
• Electrical connections – pre-wired, accessible
control box with multiple knock-outs on side in
size selections to match the National Electric
Code. Sizes range from 1/2" to 2". A grounding
screw is provided for attaching an equipment
grounding conductor.
• Water connections – hot outlet and cold inlet
are 1-1/4" NPT dielectric nipples which prevent
excessive turbulence of heated water and
results in optimum tank draw.
• Heavy insulation – an effective blanket of
insulation completely surrounds tanks to limit
heat loss and assure high operating efficiency.
• Single panel control box – with hinged
stainless steel door, provides immediate access
to all electrical components and elements.
• Stainless steel legs – 6" stainless steel legs
are provided with each unit.
• Terminal block – all models are equipped
with UL Listed terminal blocks for simplicity of
installation. The terminal block will accept either
copper or aluminum field connect wire.
