Crystal Cold Propane Refrigerator/Freezer

Unlike standard electric refrigerators that use a compressor, this unit uses a gas absorption system that relies on a heat source—in this case, propane—to circulate the refrigerant. This process is completely silent, has no moving parts to wear out, and allows the fridge to operate entirely off-grid.

Yes, the unit is designed to run on propane, but it can be converted to natural gas. You will need to ensure the conversion is handled correctly to maintain safe and efficient operation.

Yes, the 21 cubic feet represents the total interior volume of the appliance, which includes both the refrigerator and freezer compartments. It is a large-capacity unit, making it well-suited for long-term food storage in remote cabins or off-grid homes.

This model is specifically engineered to maintain consistent cooling even in warmer environments. However, because it relies on gas absorption, proper ventilation is critical for the unit to dissipate heat effectively and maintain optimal internal temperatures.

Maintenance is minimal but essential for safety and efficiency. You should periodically clean the burner assembly and ensure the flue is clear of any debris or soot buildup to keep the flame burning clean.

The cooling system itself is powered entirely by propane, meaning it does not require an electrical hookup to keep your food cold. However, some models may use a small amount of battery power for interior lighting or ignition systems.
