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 –
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.
• 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.
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.
