Dual refrigeration means superior preservation

Fresh foods need chilly, humid air to stay fresh. Frozen foods require frigid, dry air to preserve flavor. Yet the typical refrigerator-freezer compromises, using a single compressor that lets air circulate between the two sides. Ever tasted fishy ice cubes? That’s why. Not with Sub-Zero. We don’t compromise food’s freshness and flavor. Our built-in has dual refrigeration — separate, sealed systems for refrigerator and freezer that ensure optimum preservation conditions for each type of food.

The freshness air force.

A whole suite of technologies makes the Sub-Zero built-in the ultimate preserver of freshness. An antimicrobial air purification system, based on technology from the space program, scrubs the air of mold, bacteria, viruses, and ethylene, a gas naturally emitted by foods such as apples that hastens spoilage.

Freshness is in the cards.

To help you make the most of all this innovative food preservation technology, freshness cards inside the refrigerator show you the optimum storage temperature for each type of food. They even tell you which foods not to refrigerate!

Deliciousness dialed in

Digital controls keep the temperature within 1°F of where you set it. Doors seal magnetically on all four sides, locking in cold air and saving energy. There’s even a “fridge within a fridge,” a lower-temperature, higher-humidity zone that keeps vegetables crisp and flavorful even longer.
