• 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. 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.

Certifications and Ratings:

• Wiring options –

simultaneous and non-simultane­ous 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

• 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
Massachusetts Code compliant.

CERTIFIED FOR A 150 PSI MAXIMUM WORKING PRESSURE.
