Sun Frost Refigeration    The Sun Frost is so outstandingly energy efficient, it makes powering a home with photovoltaics or other low output energy sources both feasible and affordable. Even in a home using conventional utility power, energy consumption for refrigeration is typically cut by a factor of four!
    In addition to unrivaled energy efficiency, Sun Frost offers other amenities not found in conventional refrigerators, such as food-saving, high humidity storage, ultra-quiet operation and an easy-to-clean interior.
    Every Sun Frost is custom crafted, and can be finished with a number of laminates or wood finishes.


Sun Frost RF16 with 13" cabinet.SUN FROST RF16
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 Refrigerator / Freezer
shown with 24" cabinet.SUN FROST RF12
The Sun Frost RF12 is a single compressor refrigerator freezer with a passively cooled (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 RF19 Refrigerator / Freezer
shown with 13" cabinet.

Sun Frost RF19, R19, and F19
These refrigerators and freezers are our largest models, and all have two equal sized compartments.

The Sun Frost RF19: 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. 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: is 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: is 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.


The following models are the same width & depth as our larger models but are shorter, and for maximum convenience would require a higher base cabinet.

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 F4Sun 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.

Solar Powered Vaccine Storage DC Refrigerator Freezer
The Sun Frost RFVB is a vaccine storage refrigerator used primarily in developing countries. There is more information about this model on its own spec page.


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.

The Sun Frost RF-19 and F-19 use a quiet and highly efficient fan to help cool the condenser; on other models, the condensers are cooled passively. Because of the efficient design of the Sun Frost, the compressors used 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.

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 which 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.

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.

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 RF-16 12 volt DC model consumes 20 KWH per month, or an average of 53 amp hours per day. By contrast, conventional refrigerators typically consume about 110 KWH per month or 305 amp hours per day. Producing the 110 KWH needed to run this refrigerator on a solar power system would require an investment of around $12,000 in hardware, batteries, and inverter. A Sun Frost 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.

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.

During the summer, a typical refrigerator adds as much heat to your kitchen as a 1000 watt heater running five 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.

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 RF-16 and RF-19 refrigerators and a 24 inch high cabinet for the Sun Frost RF-12. Each cabinet has two large side-by-side drawers. There is also a 4 inch stand with no drawers or storage space for the RF-19 if desired.
