The Sub-Zero Designer 36″ All Refrigerator with Internal Dispenser delivers an impressive 16.4 cu. ft. of well-organized refrigerator storage in its upper cabinet and two drawers below – likely at least 50% more than you have now. Pair it with an all-freezer unit, and you’ll have flavorful food on hand no matter how large your family is or how often you entertain. Rest assured it will stay fresher longer, thanks to the DET3050RID’s advanced food preservation features. Sub-Zero refrigerators come with an air purification system (based on technology developed by NASA) that scrubs the air of ethylene and odor every 20 minutes. 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. An internal dispenser delivers fresh, filtered water. As with all designer models, it can be fitted with stainless steel panels or custom cabinetry panels to virtually disappear into your décor.
