ARB fridge freezers are the ideal way to keep your food and beverages chilled or frozen on your 4x4 adventures, regardless of ambient conditions. Not to be confused with less effective 12 volt 'coolers', the ARB unit is a true refrigerator/freezer.

Many other 12-volt coolers use weak compressors to reduce the temperature of your food and beverages. ARB fridge freezers come equipped with robust Danfoss compressors to provide powerful refrigeration that can actually cools your food and drinks down--and then keeps them cold. All ARB fridge freezer models are capable of reducing the interior temperature to 0 degrees Fahrenheit. ARB fridge freezers are designed to both actively and passively cool your food and drinks--even while the vehicle is off. When the internal temperature of the fridge rises above the digital thermostat's setting, the compressor activates to cool the contents back down. The adjustable integrated battery protection system allows the fridge to sip battery power while your vehicle is off, keeping your food and drinks cold without overly draining your battery. Heavy duty insulation and hardware helps maintain chilly temperatures. The 50-quart model is able to maintain sub-freezing temperatures in 90 degree heat while only drawing 0.87 amps per hour from a 12-volt power source. That's less power than a single headlamp draws. Once to temperature, ARB fridge freezers consume the least amount of power when compared to other leading brands.
