You know you want a Sub-Zero. It’s hard to ignore the beautiful efficiency, premium features and durability of Sub-Zero refrigeration. But what makes a Sub-Zero refrigerator so special is the job it does protecting your food. With Sub-Zero dual refrigeration, you protect your food and always ensure you get the best flavors and most pleasurable meals. Sub-Zero refrigerators are built to keep the dry side dry and the humid side humid.
With Sub-Zero, each refrigerator and freezer area has its own dedicated, sealed system with compressor and evaporator, so fresh and frozen foods maintain their individual integrity for much longer.
Fresh and frozen foods have different preservation needs. Fresh foods do best in a humid yet chilly climate to maintain their integrity, while frozen and convenience foods require dry, frigid air to prevent decay and freezer burn.
Other refrigerator/freezers compromise, using one compressor to cool both areas, so neither climate is ideal. Extra energy is also consumed as each side works against the other as it tries to maintain its core temperature. In addition, defrosting has to be done more often, and undesirable aromas and flavors are transferred around by the shared air system.
With a 60-year legacy as a refrigeration specialist, the results of dual refrigeration speak for themselves: Sub-Zero owners report that their fruits and vegetables retain vitality 20% longer. That can translate into big savings when you realize that the average American household tosses nearly 500 pounds of food — worth $600 or more — annually. Sub-Zero owners save time and money every day, because their fresh produce and frozen foods stay fresher longer.

Sub-Zero's Microprocessor Control Guarantees Peak Performance.

Airtight Seals Boost Performance, Reduce Energy Use
How does Sub-Zero do it?
Aside from the dual refrigeration, Subzero combines a state of the art microprocessor, superior door seals and advanced freshness technology to create the most stable and optimized environment for your food. The microprocessor preserves your food by adjusting to your individual climate so foods are kept at their ideal temperatures, varying by only one degree of your set point. Extra heavy insulation and magnetic gaskets around every door and drawer ensure that seals are secure, saving energy and food, even in the event of power outages!
Sub-Zero is built to keep the cold in. Our patented air purification system on our built-in series was inspired by a similar system developed for NASA. Every 20 minutes, it scrubs the air of ethylene gas naturally emitted by apples, melons, peaches and other produce, reducing spoilage and saving flavors.
For freshness above all, step up to a Sub-Zero.
