Atwood Helium refrigerators are standard with upscale features including built-in door ajar alarm, designer blue crisper bins and LED lights, intuitive door handles and a modern display panel. As the name suggests, helium gas has replaced the hydrogen traditionally found in gas absorption refrigerators. The result is a cooling system that runs cooler and minimizes stress that can be caused by using a gas absorption refrigerator in an out of level situation. An integrated tilt sensor also provides a visual cue to let you know if the refrigerator is being used in and out of level situation. Door panels must be ordered separately.
