Rheem 115 - Manual

Commercial Storage Tanks
Available in 80, 115 and 175 Gallon Models
Rheem-Ruud commercial storage tanks are vertical tanks
designed for applications that require large quantities of hot water
in short periods of time. When used in tandem with Rheem-Ruud
commercial water heating equipment, these storage tanks
provide the flexibility needed for many Commercial applications.
Installed individually, or in parallel manifold, these storage tanks
can provide 80% draw capability without an appreciable
temperature decrease in single temperature applications.
Construction Features:
• Long life tank design –
proprietary steel formulation
with two coats of high tem-
perature porcelain enamel
to maximize corrosion
resistance resulting in a
superior tank design. Two
heavy duty magnesium
anode rods are installed for
longer tank life.
• Space saving design –
unlike other storage tanks,
the ST80 and ST120 can
pass through a 30" opening
and the ST175 only
requires a 33" opening –
ideal for boiler room doors.
• Efficient design –
2" of rigid polyurethane
foam insulation provides
superior insulating qualities
resulting in reduced operat-
ing costs. Our patented
process of injecting foam
into the insulating cavity
adds additional durability
and toughness to the baked
enamel steel outer jacket.
• Tank openings –
circulating line connections
and hot outlet are 2" NPT
on the ST80 and ST120
and 2-1/2" NPT on the
ST175. Other openings are
provided for relief valve and
temperature control.
ST175 equipped with a
hand-hole cleanout.
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)).
• Optional construction – ASME construction is available on all
storage tank models. Model numbers are ST80A, ST120A and
ST175A
• T&P valve – must be ordered separately based on water heater
BTU input.
