You may like the Sub-Zero 36" French door refrigerator for its bold, stylish look. But it has its practical side too. It makes your kitchen feel more spacious, because only half a door swings out. Nice if you have a galley kitchen, or assorted friends and family members often milling about. Of course since it's a Sub-Zero, it has an even more profound advantage -the most advanced food preservation features in the industry - features developed through almost 70 years of research.
Dual refrigeration ® provides the ideal humid yet chilly conditions for fresh foods, along with dry, frigid air for frozen and convenience foods. A NASA-inspired air purification system scrubs the air of ethylene gas, bacteria, mold and viruses. And it has new brighter LED lighting for better interior views, and a discreet interior water dispenser with filtration system. Capacity for the BI-36UFDID is a generous 15.7 cu. ft. refrigerator, 5.3 cu. ft. freezer. Bottom line? Fresher, more delicious food for you, your family, your guests.

Discreet interior water dispense with advanced filtration

Provides up to 35 oz. of chilled, filtered water without disturbing the seamless design of your kitchen. An advanced water filtration system significantly reduces contaminants, while preserving water's fresh, clean taste.

LED Lighting for brighter interior

See all your fresh foods more clearly and easily. LED lighting is also more energy-efficient - designed to last the life of your refrigerator.

Dual refrigeration keeps food fresher longer

This technology pioneered by Sub-Zero features two separate cooling systems. Fresh food stays fresher in the cool, moist air of the refrigerator, while frigid, dry air prevents frost and freezer burn in the freezer - optimum preservation conditions for each type of food.

Air purification system fights spoilage, odors

Many fresh foods emit ethylene gas, a natural compound that hastens spoilage. Sub-Zero's built-in refrigerators come with an anti-microbial air purification system (based on technology developed by NASA) that scrubs the air of ethylene, as well as mold, viruses and bacteria, every 20 minutes.

Crispers and deli drawers in low-temp, high-humidity zones for optimum freshness

Crispers and deli drawers are strategically located near the evaporator to maintain temperatures a few degrees cooler than the rest of the unit. Drawers are sealed to lock in humidity and ensure freshness.

Microprocessor control assures peak performance

The state-of-the-art microprocessor preserves your food by adjusting to your individual climate and schedule. It continuously monitors each section of your Sub-Zero for pinpoint climate control, so foods are kept at their ideal temperature, varying by only one degree of your set point. Also lets you finesse your lighting and cooling fan, tells you if your door is ajar, and defrosts when it's most convenient for you.

Freshness cards for maximum food preservation

Different foods require different storage procedures. That's why, inside each refrigerator, you'll find "freshness cards" that provide easy-to-follow tips for ensuring maximum food preservation.

Rigorously tested in our U.S. manufacturing facilities to ensure decades of use

Every component of every single Sub-Zero unit is tested in its U.S. manufacturing facilities before assembly, then every completed product is factory-tested for up to 24 hours before shipping. In its labs, components are subjected to electric jolts, violent vibrations and 350 temperature swings, and tested to stand up to at least 20 years of heavy use.

Exceptional 24/7 support from Madison, WI-based Customer Care team

Whether you're shopping for appliances or have questions about those you already own, the Sub-Zero, Wolf, and Cove Customer Care team has a reputation for service that's as exceptional as its products. They're based in Madison, Wisconsin, just footsteps from the factory, and are standing by to provide expert, friendly, problem-solving support.

Over-and-under refrigerator/freezer storage

Built-in over-and-under units feature easy-access refrigerator storage above a full-extension, roll-out freezer drawer containing two-tier wire baskets.

Magnetic door seal system locks in cold air

One-piece construction, extra-heavy insulation and magnetic gaskets around every door lock in cold air. Seals are so secure that even after power outages of multiple days, owners report no thawing of their frozen foods!

Automatic ice maker with "max ice" feature

Provides crescent-shaped ice cubes and includes a "max ice" feature capable of increasing ice production by an average of 30 percent for a 24-hour period - just the boost you need for parties and holidays.

Adjustable shelves for maximum convenience

Food comes in all shapes and sizes, and the interior design of Sub-Zero refrigerators and freezers accommodates that diversity. Main shelves, door shelves, even dividers in drawers adjust to allow the most convenient configuration possible.
