With dual refrigeration, fresh foods thrive in a humid yet chilly climate, while frozen and convenience foods get the dry, frigid air they need. An air purification system inspired by NASA technology scrubs the air of ethylene gas, bacteria, mold and viruses. A magnetic door seal system locks in cold, while an advanced microprocessor provides pinpoint climate control. Storage capacity for the BI-48S is a generous 19.1 cu. ft. refrigerator, 9.8 cu. ft. freezer. Bottom line? More flavorful, delicious food for you, your family, your guests.
Dual refrigeration keeps food fresher longer
This technology pioneered by Sub-Zero features separate compressors and cooling systems for the refrigerator and freezer. Fresh food stays fresher in cool, moist air on one side, while frigid, dry air prevents frost and freezer burn on the other - 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
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.
Water-filtration system reduces contaminants, chlorine taste and odor
Designed to reduce contaminants and chlorine taste and odors when purifying water or ice, this low-maintenance system uses a filter built to last 1 year or 750 gallons. Replacement is fast and easy.
Freshness cards for maximum food preservation
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.
Rigorously tested in our U.S. manufacturing facilities to ensure at least 20 years of heavy use
Every component of every single Sub-Zero unit is tested in our U.S. manufacturing facilities before assembly, then every completed product is factory-tested for up to 24 hours before shipping. In our 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.

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!
Automatic ice maker with "max ice" feature
High-efficiency unit 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 our refrigerators and freezers accommodates that diversity. Main shelves, door shelves, even dividers in drawers adjust to allow the most convenient configuration possible.
