Have you ever noticed food in your standard refrigerator developing an odd smell from the freezer? That’s because in a typical refrigerator, cold air in your freezer goes down to the refrigerator compartment, which in turn cools the refrigerator section. And when air mixes between the two compartments, odors also mix. What’s more is, dry frigid air in your freezer mixes with the moist, humid air in your refrigerator, and vice versa, producing a lot of frozen ice crystals that surround your frozen goods. And this is not the ideal environment for food preservation.

To maintain its flavor and quality, fresh produce needs chilly, humid air, while frozen food requires frigid, dry air. Technology pioneered by Sub-Zero features two separate cooling systems so fresh food stays fresher longer in the cool, moist air of the refrigerator, and frigid, dry air prevents frost and freezer burn in the freezer.

Creating food with integrity begins with using ingredients that are preserved with integrity. Sub-Zero’s dual refrigeration creates separate, sealed systems for the refrigerator and freezer to ensure the optimal humidity of both, not compromising the taste, quality, and freshness of food.
