Cold is cold, right? Not quite.
There’s more to preservation than keeping food cold. Sub-Zero built-in refrigeration products guard freshness by addressing the three pillars of food preservation: temperature control, proper humidity, and purified air.
Consistency counts for a lot in keeping food fresh longer. Sub-Zero’s microprocessor controls monitor the refrigerator’s interior temperature and hold it within one degree of the temperature you set. A new, more advanced seal around all four sides of the door locks in cold air and holds down energy use.
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 cooling system to attempt both jobs; refrigerator and freezer share air — too dry for fresh foods, too humid for frozen.
Sub-Zero doesn’t compromise. Dual refrigeration — separate, sealed systems for refrigerator and freezer — ensures optimum preservation conditions for each type of food. And a special seal on the produce drawers creates what we call a "crisper crisper" to preserve the goodness of fresh vegetables even longer.
NASA-inspired air purifcation
Many fresh foods (apples chief among them) emit ethylene gas, a natural compound that hastens spoilage. Our antimicrobial air purification system - inspired by a similar system developed by NASA - scrubs the air of ethylene gas every 20 minutes.
It also reduces odors by removing bacteria, mold and viruses - contaminants too small for conventional filters. So your food stays fresher longer, smells fresher, and has a more flavorful, delicious taste.
Options to enhance any kitchen design
Start by choosing a look – doors either wrapped in stainless steel or customized with any cabinet panel and hardware you want (including handles that coordinate with Wolf cooking equipment). From there, the vast range of built-in models lets you suit your functional and aesthetic preferences to a T.
Widths from 30 to 48 inches, and every model a uniform 84" tall for easy pairing in dual installations. French door, glass door, models with internal or external ice and water dispenser. All refrigerator, all freezer, side-by-side, or over-and-under configurations are all available.
