sumer of electricity. But the super-efficient SUN
FROST refrigerator makes these alternative technologies both feasible and affordable.
 In a home using utility power, SUN FROST normally cuts energy consumption by 80%.
 Along with energy efficiency, the SUN FROST offers other advantages not found in
conventional refrigerators including food-saving high-humidity storage, quiet operation, and
an easy-to-clean interior.
 With its clean, uninterrupted lines and choice of more than 100 colors and numerous natural
wood finishes, the custom-built SUN FROST refrigerator adds elegance to every kitchen.

When dust and cobwebs collect on a cooling system, they lower its
efficiency. The top-mounted condenser on the SUN FROST refrigerator
s accessible and easy to clean, allowing the cooling system to continue
unning efficiently.
EFFICIENT DEFROST
Defrosting a SUN FROST is a simple process. Frost buildup in the SUN
FROST freezer is very slow because there is no air circulating between
he freezer and the refrigerator sections. The ice which forms in the
reezer collects primarily on the ceiling.
When defrosting the freezer section, the contents of the freezer may
be transferred to the refrigerator section so they remain frozen. After
he freezer has been turned off for about twenty minutes, the ice is
easily removed in large pieces. There is no mop-up because the ice
does not need to be melted, only separated from the flat ceiling.

RELIABLE
The cooling system of the SUN FROST refrigerator contains a minimal
number of moving parts. Both the DC and AC compressors
incorporate highly reliable, hermetically sealed, brushless motors.
The efficient thermal design of SUN FROST refrigerators also
contributes to the reliability. The top-mounted cooling system runs at
a lower temperature than most, which prolongs the life of the
systems lubricants and reduces mechanical strain on the
compressor. The cooling system is designed to provide typically over
twenty years of trouble-free operation.
FEWER SOLAR PANELS
The SUN FROST refrigerator typically reduces refrigerator
energy consumption by a factor of five. The accompanying cost
of the solar power system is similarly reduced. The SUN FROST
RF16 typically consumes 15 KWH per month. By contrast, the
average refrigerator in a home typically consumes about 90 KWH
per month.
Producing the 90 KWH needed to run this refrigerator in an
off-grid solar power system would require an investment of at
least $10,000 in hardware.

SENSIBLE USE OF KITCHEN SPACE
CUSTOM FINISHES
SUN FROST refrigerators are designed to be mounted on a cabinet.
With the refrigerator raised, all stored food will then be at a convenient
height. In addition, a cabinet beneath the refrigerator provides much
more accessible storage space than an overhead cabinet. This base can
be built by the homeowner to match other kitchen cabinets or supplied
by SUN FROST. SUN FROST manufactures a 13" high cabinet for the
RF16 and RF19 refrigerators and a 24" high cabinet for the RF12. Each
cabinet has two large side-by-side drawers. A SUN FROST refrigerator
can be placed against a wall, minimizing floor area utilized. It will not
have to be moved for either cleaning or servicing.
Each custom-built SUN FROST refrigerator is
available in more than 100 colors of high-pressure
laminate and many natural wood finishes. The
spacious interior, made from sturdy fiberglassreinforced plastic, is exceptionally easy to clean
with no exposed ducts, tubing, or inaccessible
corners. The adjustable door shelves can
accommodate half-gallon beverage containers,
while adjustable glass shelves line the refrigerator
section.
Sun Frost RF16 shown with 13" Cabinet
The Sun Frost RF16 is an extremely efficient fullsize refrigerator. It has two independent cooling
systems and temperature controls. In fact, one
compartment may be left running while the other
is shut off. The uniquely designed cooling coils
on the outside of the Sun Frost do not require
fans. The Sun Frost RF16 may be mounted on a
13-inch high cabinet for maximum convenience.
Sun Frost RF19, R19, and F19
shown with 13" Cabinet
These refrigerators and freezers have two
compartments of equal size.
The Sun Frost RF19: one compartment is a
refrigerator and the other a freezer. The RF19
can be ordered with the freezer on the top or on
the bottom. The freezer is twice as large as the
freezer in the RF16; however, the refrigerator
compartment is slightly smaller than that of the
RF16. The RF19 often eliminates the need to
buy a separate freezer. Like the RF16, this model
is typically mounted on a 13-inch high cabinet.
The RF19 uses two quiet and highly efficient fans
to cool the exterior cooling coils.
The Sun Frost R19: a refrigerator-only model with
two equal-sized refrigerator sections. It does not
need defrosting and incorporates a passive (no
fans) cooling system.
The Sun Frost F19: our largest freezer-only unit.
It has two equal-sized compartments
incorporating two independently controlled
cooling systems. One compartment may be
turned off to conserve energy when its storage
space is not required. It uses the same fans as
the RF19 to cool its cooling coils.
Sun Frost RF12 shown with 24" Cabinet
The Sun Frost RF12 is a single-compressor
refrigerator/freezer with a passive (no fans)
cooling system. For convenience it is typically
mounted on a 24" high cabinet. The matching
cabinet made by Sun Frost has two large side-by
side drawers.
Sun Frost R10 and F10
The Sun Frost R10 and F10 are the same width
and depth as our larger models but are shorter,
and for maximum convenience would require a
higher base cabinet. The R10 is a refrigeratoronly unit and the F10 is a freezer-only unit.
Sun Frost RF4, R4, and F4
The Sun Frost RF4, R4, and F4 are our smallest
refrigerators and freezers. They are the same
width and depth as the larger units. The RF4
consists of a refrigerator with an ice tray freezer
section. The R4 is a refrigerator-only unit, and
the F4 is a freezer-only unit. For convenience,
these units would require a higher base cabinet,
or they could be placed on a countertop. Our 4
cubic foot models are also ideal for use in bus
conversions, boats, and RVs.
