Monitor temperature, voltage, and more on the go with an ARB Zero Series fridge freezer. Featuring Bluetooth wireless technology, every ARB Zero Series fridge freezer monitors and controls temperature (multi-zone for dual-zone models), compressor status, battery voltage, setting mode (up to three user-defined modes), and power – all via your Android or Apple Bluetooth enabled device! ARB Zero Series fridge freezers also feature a quick-release lid that can be mounted to the front or side of the fridge freezer, for your choice of front or side-opening access. The fridge freezers also have dimmable LED control panels, front and rear DC-power inlets, a front AC power inlet, and a USB port next to the front control panel – perfect for charging mobile phones! Inside, the LED interior lights provide nighttime illumination, the versatile internal basket system can be easily maneuvered or removed, integrated evaporation system reduces condensation, and the highly-efficient, variable-speed compressor provides fast and accurate temperature control. Outside, the durable steel outer casing has built-in full height corner moldings for added protection, plus recessed carrying handles with integrated tie-down points. Available in single zone or dual zone configurations. Single Zone fridge freezers feature one temperature controlled compartment while Dual Zone fridge freezers features two, independently controlled compartments.
