3KW - 12KW Electric Commercial Water Heaters
Available in 30, 40, 50, 65, 80 and 120 Gallon Tank-Type Models

3KW thru 12KW
Electric commercial water heaters are designed to provide hot water where
applications require moderate quantities. These units are suited for a wide
variety of applications such as retail stores, small offices or any location
where a moderate amount of hot water is required.
Construction Features:
•Long life tank design –
proprietary steel formulation with a
unique coat of high temperature
porcelain enamel to maximize cor-
rosion resistance resulting in a
superior tank design. A patented
R-Tech anode rod provides
advanced technology; equalizing
aggressive water action while
prolonging the effective life of the
anode rod and in turn the life of
the tank.
• Long life heating elements –
our patented resistor elements are
designed with a specially treated,
double layer of magnesium oxide
and copper to resist corrosion.
Replacement elements screw
in easily.
• Wiring options –
simultaneous and non-simultane-
ous wiring, single phase and three
phase available.
• Effecient design –
2-1/2" of rigid polyurethane foam
insulation provides superior
insulating qualities resulting in
reduced operating costs.
• Automatic temperature control –
a surface mounted thermostat
automatically cycles on and off to
maintain the water temperature
at a desired preset level.
• Durable brass drain valve
Certifications and atings:
• Efficiency – these models have been tested according to DOE test
procedures, and exceed the minimum energy factor requirements of
ASHRAE (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 174 as electric
storage tank water heaters. All models are North Carolina and
assachusetts Code compliant.
