Dual Refrigeration Ensures Pleasurable Meals, Protects Food Investment.
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 — and maintain them 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
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.
