Efficiency - Plus
The Sun Frost refrigerator employs an array of design innovations to achieve its exceptionally low energy consumption. The cooling system on the Sun Frost is top mounted. This configuration reduces energy consumption several ways. The heat generated by the compressor and condenser (black coils on the back of many refrigerators) does not re-enter the refrigerator and also with a cooler running condenser, the efficiency of the cooling system is increased.

Quiet Operation
The condensers on Sun Frost refrigerators and freezers are cooled passively, except our RF19 and F19 models, which use a quiet and highly efficient fan to help cool the condenser. Because of the efficient design of the Sun Frost, the compressors  used run less often, are much smaller and produce correspondingly less noise than those found on a conventional refrigerator. These features make the Sun Frost much quieter than a conventional AC refrigerator.

Simple Defrost System
Defrosting a Sun Frost is a simple process. Frost build-up in the Sun Frost freezer is very slow because there is no air circulating between the freezer and refrigerator sections. The ice that forms in the freezer 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 the refrigerator 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.

Superior Storage Conditions
Sun Frost refrigerators keep food fresher by maintaining high humidity. This prevents freezer burn and wilting caused by water loss in food. Since there is minimal water loss in foods stored in a Sun Frost, foods often last two to three times longer than in conventional refrigerators. In typical refrigerators, water, which is part of stored food, is transformed into ice on the freezer's cooling coils. This process results in the dehydration of fruits and vegetables, increases energy consumption, and accelerates frost build-up. In a conventional refrigerator, high humidity is achieved by storing food in airtight containers, which creates high humidity conditions, but cuts off the food's oxygen supply. Without oxygen, plant cells break down more rapidly, which decreases shelf life. The Sun Frost allows you to store food in breathable containers, such as paper bags, often more than doubling storage life.

Fewer Solar Panels
The Sun Frost refrigerator typically reduces refrigerator energy consumption by a factor of five compared to the typical household refrigerator currently in use. The accompanying cost of the solar power system is similarly reduced. The Sun Frost RF16 12 volt DC model consumes 15 KWH per month, or an average of 42 amp hours per day. Producing the 110 KWH needed to run the typical refrigerator on a solar power system would require an investment of around $12,000 in hardware, batteries, and inverter. A Sun Frost RF16 will reduce this cost by a factor of at least six because of its increased efficiency and the elimination of inverter losses. Inverters convert DC battery power to 120V AC at an energy loss of about 10%.

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 their reliability. The top-mounted cooling system runs at a lower temperature than most, which prolongs the life of the system's lubricants and reduces mechanical strain on the compressor. The cooling system should provide well over 15 years of trouble-free operation.

Cooler Summer Kitchen
During the summer, a typical refrigerator adds as much heat to your kitchen as a 1000 watt heater running four hours per day! The energy needed by your air conditioner to remove this excess heat will be about half the energy consumed by your refrigerator. Increasing the cost of running your refrigerator by an additional 50%. By producing much less waste heat than a conventional refrigerator, a Sun Frost makes your kitchen more comfortable and reduces the cost of air-conditioning your home.

More Sensible use of Kitchen Space
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 a ceiling mounted cabinet. The cabinet could be built by the homeowner to match other kitchen cabinets or supplied by Sun Frost. Sun Frost manufactures a 13-inch high cabinet for the Sun Frost RF16 and RF19 refrigerators and a 24-inch high cabinet for the Sun Frost 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.

Rugged Design
Sun Frost refrigerators and freezers are ideal for use in boats, RVs and conversion buses.  All Sun Frost refrigerators are completely rust-proof.  There is no need to level the refrigerator, and vibration will not affect its operation.  Sun Frost refrigerators can also run directly off of batteries, so no generator is necessary.

Custom Styling and Finishes
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 fiberglass-reinforced 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. Ask us about our new stainless steel option!

Sun Frost RF16
shown with 13" Cabinet
The Sun Frost RF16 is an extremely efficient full-size 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 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 & depth as our larger models but are shorter, and for maximum convenience would require a higher base cabinet. The R10 is a refrigerator-only 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. Like the R10 and F10, they have 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.

We recommend using a cabinet below your Sun Frost refrigerator/freezer to elevate the refrigerator to a more convenient height, while providing storage room for dry goods. A cabinet 12” to 16” high works well with our RF16 or RF19 models. For our RF12, we recommend a cabinet 18” to 24” high. Our 4 cubic foot and 10 cubic foot models can be placed on top of existing cabinets, or at a height of about 36”.

Sun Frost offers 13” and 24” high cabinets with two side-by-side sliding drawers, which can be made in laminates or woods to match your refrigerator. We also offer a 4” stand for areas in which there is not enough overhead space to install a full cabinet. The 4" stand is open in the front and creates a kick space under the refrigerator.

If you choose to build your own cabinet, it should be constructed of a minimum 3/4” plywood for sufficient strength.
