The Sub-Zero 30” Designer Refrigerator Column delivers an impressive 17.5 cu. ft. of well-organized refrigerator storage – likely at least 50% more than you have now. Pair it with its partner, the Sub-Zero 30” Designer Freezer Column, and you’ll have flavorful food on hand no matter how large your family or how often you entertain. Rest assured it will stay fresher longer, thanks to the DEC3050R’s advanced food preservation features. NASA-inspired air purification scrubs the air of ethylene gas that hastens food spoilage, and also reduces odors by removing bacteria, mold and viruses. A magnetic door seal system locks in cold, while a state-of-the-art micro-processor precisely controls temperatures. Crisper and deli drawers form a lower-temperature zone ideal for produce and meat. As with all designer models, it can be fitted with stainless steel panels or custom cabinetry panels to virtually disappear into your décor.
