The world's most elegant refrigerators are also the most efficient!

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.

For the past 19 years, Sun Frost refrigerators/freezers have been used in over 50 countries and have an excellent track record.  Sun Frost units are ruggedly constructed and will provide many years of reliable operation, even in the harshest environments.

The Sun Frost RF4, R4, and F4 are our smallest refrigerators and freezers. 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.

Product Applications:
• Boats, RVs, conversion buses. No need to level refrigerator
• and vibration will not affect its operation
• Can run by photovoltaic or utility power
• Can run directly from battery, no generator necessary

Solar Photovoltaic Power:
In an energy-efficient home powered by photovoltaics or other low-output energy sources, refrigeration is typically the largest consumer of electricity. But the super-efficient SUN FROST refrigerator makes these alternative technologies both feasible and affordable.

The cost of a solar power system is typically more than the cost of a refrigerator, so efficiency is of prime importance in reducing system costs.  As a result of the extremely low energy consumption of Sun Frost units, the cost of a power system will be drastically reduced.

Utility Power:
In a home using utility power, SUN FROST normally cuts energy consumption by 80%

Product Highlights:

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
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.

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.

Custom Styling and Finishes
Each custom built Sun Frost refrigerator is available in more than 100 colors of high-pressure laminate, many natural wood finishes and now a new stainless steel design.

Rugged Design
All Sun Frost refrigerators are completely rust-proof. 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.

Reliability
Sun Frost refrigerators have proved themselves reliable. Over the past 12 years they have been installed in over 50 developing countries and have held up under the harshest conditions. For critical applications, far from supporting infrastructure, from Borneo to Botswana, Sun Frost refrigerators have delivered consistently dependable performance day in and day out.

SUN FROST Custom Color Choices
Sun Frost refrigerators, freezers, and matching cabinets come standard with a white laminate finish or you may choose from a variety of color and wood choices available:

Colors:   You can select from any of the matte finish laminate colors from Wilsonart, Formica, or Nevamar brands, including textures.  Please note that we are unable to work with glossy laminates because they are less scratch-resistant and durable than matte finishes.  Although these companies provide printed brochures with all of their color choices, it is not recommended that the customer make a final color decision based on printed charts as printed colors often vary from the true laminate material.  A final decision should be made using actual color samples from a “chip board.”  A chip board can usually be found at a local building supply, cabinet/countertop shop, paint or hardware store.  At the time you place your order, Sun Frost will need the brand name, color name, and color number of the laminate chosen.  There are hundreds of colors to choose from to match any decor you can dream of! 

Wood:  We can use most readily available wood species [no rare or exotic species].  Our wood finishes are generally a veneer plywood or MDF core panel.  We do not apply any finished coating or stain to our woods, allowing the customer to match existing cabinetry or finish as desired.  The most common wood finishes are oak, knotty pine, cherry, hickory, walnut, and maple.  Please call us for other wood types.

Stainless Steel:  We now offer stainless steel and faux stainless steel options.  The first consists of a high-pressure laminate backer with an overlay of real stainless steel.  Because of the high cost of this material, we cover the front of the refrigerator with stainless steel, and cover the sides of the unit in black laminate.  As a less expensive option, Wilsonart offers a faux stainless steel laminate that is very popular.  Call for details and pricing.

Unfinished:  We can also ship our refrigerators, freezers, and base cabinets “unfinished” with just bare plywood [no laminate or veneer].  The aluminum door handle[s] and trim is included but not installed on “unfinished” products.  The customer can apply his or her own finish material.  Many interesting finishes have been applied by our do-it-yourself customers including corkboard, metals, and woven rattan materials.

Sun Frost Refrigerator/Freezer Cabinet
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.
