ENERGY STAR® 21.4 Cu. Ft. Built-In Refrigerator with Air Purification

The Sub-Zero Difference: Innovation
Sub-Zero's mission of elevating the freshness of food and the design of kitchens is unmistakeably exemplified in their products. The difference between Sub-Zero and other manufacturers is their dedication to innovation. Their products are continually pushing the boundaries of refrigeration technology, and it shows in their performance. Innovation is also seen in design, as Sub-Zero treats aesthetics with the same amount of meticulous attention, creating their products with kitchen design in mind. All this and more is seen in this ENERGY STAR® 21.4 cu. ft. built-in refrigerator with air purification.
Dual Refrigeration: A Sub-Zero Innovation
Sub-Zero pioneered dual refrigeration technology. An integral part of food preservation, this system incorporates separate cooling systems for both the refrigerator and freezer, thus maintaining optimum conditions for each type of food. Cool, moist air preserves fresh foods, while frigid, dry air prevents freezer burn for frozen items.
Innovation Meets Design
This model offers a wide range of design options. Framed, overlay, flush inset, and classic stainless steel design options are available, as well as tubular, PRO, and framed handles. This allows for maximum flexibility to cater to your personal tastes.
Digital Controls Make For Consistent Results
Implementing a microprocessor, this model has a digital interior control panel that maintains a consistent temperature within 1 degree fahrenheit of the temperature you set. Its digital exterior temperature display is easy to read and lets you adjust according to your ever-changing storage needs.
Different Conditions for Different Foods
Sub-Zero owners report fruits and vegetables stay fresh 20% longer than the average household. This can be attributed to the separated deli and crisper drawers having a special, low-temperature zone which is an ideal environment for food longevity and freshness.
Air Purification System Aids Food Preservation
Thanks to air purification technology Sub-Zero borrowed from NASA, your food will be stored in the purest environment possible. The antimicrobial air purification used in this model removes mold, bacteria, viruses, odors, and ethylene gas from the air and pushes it out of the system every 20 minutes. Thus, it is not just a refrigerator you are putting your food into, it is a food preservation system.
