Sub-Zero® 21.0 Cu. Ft. Stainless Steel Built In French Door Refrigerator-BI-36UFD/S/PH

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

• 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.

Low-Temperature/High-Humidity Storage Zones

• 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.

Helpful Freshness Cards

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

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.

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.

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.

Microprocessor Control Guarantees Peak Performance

• Our 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.

Magnetic Door Seal System Locks In Cold Air

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

Adjustable Shelves For Maximum Convenience

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