It isn't. It has heaters in the rear. Either 12V or 120V or propane, it takes what it takes to keep the fluid circulation.
Either way, it is about 4X less efficient than a modern domestic fridge. That doesn't make it a bad fridge, merely one that increasingly appeals to a smaller group of people.
Given the cost of Dometic fridges, it's worth looking at the super-efficient 12V marine compressor fridges. They are very pricey though.
