Sub-Zero‘s new 24-in. integrated refrigerator/freezer column is the slimmest Sub-Zero refrigerator/freezer ever, so it fits into the tightest galley or high-rise kitchen. At the same time, this refrigerator delivers advanced food preservation. And because it’s a column – just one solid door, no horizontal lines – it blends into the kitchen design and is available with a cabinetry or stainless front. Two separate cooling systems ensure that the refrigerator gets the moist air it needs, while the freezer stays dry. NASA-inspired air purification scrubs away ethylene gas that hastens food spoilage and removes bacteria, mold and viruses. A magnetic door seal system locks in cold, while a microprocessor precisely controls temperatures.
