Sub-Zero understands the importance you place on owning a refrigerator that is beautifully designed and aesthetically appealing. Beyond that, Sub-Zero knows that first and foremost, refrigerators must do what they are designed to do in the most efficient manner possible. With dual refrigeration, Sub-Zero provides what no other refrigerator company does—superior food preservation.
Sub-Zero Freezer Company is the only refrigeration company to offer a dual refrigeration system as a standard feature. The dual refrigeration system keeps fresh food fresher and preserves frozen food longer because it has two separate, self-contained cooling systems—one for the refrigerator and one for the freezer. The system ensures there is no transfer of air from the fresh food compartment to the frozen food compartment.
