FACTORY JACKETED AND INSULATED
SOLAR COMMERCIAL STORAGE TANKS
These storage tanks are eligible
for a 30% federal tax credit
when installed as part of a
complete commercial solar
thermal hot water system.
Large volume solar storage
tanks from State are designed
for storing potable water. These
storage tanks are fitted with
additional openings to suit the
specific needs of solar thermal,
commercial heat pump, and
other renewable energy
heat sources.
These tanks are available as
pre-configured Specialty Solar
Tanks and as Custom Solar
Tanks built to specified
application requirements. See
the Custom Solar Tank options
on page 4 and consult your
factory representative for
more information.
FEATURES
Specialty Solar Tanks
Vertical tanks from 140 to 2,000
gallons, horizontal tanks from 200 to
1,000 gallons. State commercial solar
storage tanks are constructed with
openings for potable water and solar
thermal/renewable energy applications as
shown in the drawings that follow.
These heavy duty storage tanks have
been designed for new construction and
retrofit applications.
ASME Construction
• All tanks are ASME constructed at
160 psi working pressure. Consult
your factory representative for tanks
with greater or lesser working pressures
Glasslined
• Specialty Solar Tanks feature State's
commercial grade glasslining that
provides superior protection against
corrosion and is fused to all inner
tank surfaces at 1600°F
Insulation
• All tanks are surrounded with 3
inches of high density fiberglass
insulation to reduce costly heat loss;
insulation is non-sagging and
verminproof.To meet ASHRAE 90.1
(current edition) depth of insulation
cavity requires use of remote bulbtype tank temperature control and
thermometer. Storage tanks meet
R12.5 minimum thermal insulation
requirements of the U.S. Department
of Energy and current edition of
ASHRAE/IESNA 90.1
Jacket/Cabinet
• All tanks feature heavy gauge steel
with high quality powder coat paint
that provides additional insulating
qualities for greater energy savings
Cathodic Protection
• All tanks are furnished with factory
installed magnesium anodes designed
for maximum protection
Connections
• Tanks will be supplied with the fittings
located as indicated on the drawings
unless specified otherwise. Manhole or
handholes are optional on glasslined
tanks but are included on cement
lined tanks
Temperature Sensors
• Factory installed upper and lower
temperature sensor wells with
Pt1000 type sensors and internal
wiring pre-installed
Custom Solar Tanks
• See options and suggested
specification on page 4

CUSTOM SOLAR TANKS: Customized solar tanks with specified construction materials and configurations are also available; consult your factory sales
representative for more information.
CUSTOM OPTIONS INCLUDE:
• Glasslined tanks
• Cement lined tanks
• Stainless steel tank construction
• Specified gallon capacities up to 12,500 gallons
• Specified tank dimensions
• Specified tank openings
• Specified tank opening locations
• Outdoor models - entire tank is sprayed with minimum of 2 inch high-density polyurethane foam insulation that forms a watertight jacket that is approved for
outdoor use. Meets or exceeds the thermal efficiency and standby loss requirements of the U.S. Department of Energy and Current Edition of the
