Sub-Zero's all-new line of Integrated refrigeration includes the industry's most-advanced food-preservation features and largest selection of models. The 30"-wide Sub-Zero IC-30R column offers 17.3 cubic feet of storage, with a built-in antimicrobial air-purification system based on technology developed by NASA. This system scrubs the air of ethylene gas - an organic compound emitted by produce that hastens food spoilage - as well as mold, viruses and bacteria every 20 minutes. Another advanced food-preservation feature is the high-humidity, lower-temperature crisper drawers, which provide the perfect conditions for storing fresh produce.
