Features and Benefits in Detail
DESIGN AND PERFORMANCE FEATURES
Dual refrigeration

Each built-in combination unit comes with separate 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 — providing optimum preservation conditions for each type of food.

Maximum capacity in a 42" built-in French door model

For those moments when storage space is at a premium, the Sub-Zero 42" over-and-under with French door provides nearly 25 cubic feet of combined refrigerator and freezer capacity. That's more usable space than any built-in French door model, with a refrigerator that's 12% roomier than a Sub-Zero 42" side-by-side model, too.

Excellent design flexibility

Sub-Zero's built-in refrigeration models can be outfitted with stainless-steel panels or custom cabinetry panels, and may be installed flush with surrounding cabinetry for a more integrated look. Handle and grille styles are also customizable. For full details on installation and design options, see the Sub-Zero Design Guide.

Air purification system

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.

Water filtration system

This low-maintenance system reduces suspended particles and chemical pollutants and filters out chlorine taste and odors in water used for ice production. The filter lasts for 1 year or 750 gallons, and replacement is fast and easy.

Bright interior lighting

Evenly distributed interior lighting — powered by specially designed 40-watt appliance bulbs in the refrigerator and freezer — illuminates food on shelves and in storage drawers when unit doors are open.

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 freshness.

Informational freshness cards

Different foods require different storage procedures. That's why, located inside each built-in refrigerator unit, specially designed freshness cards provide easy-to-follow tips for ensuring maximum food preservation.

Ice making features

An automatic icemaker provides crescent-shaped ice cubes and includes a "max ice" feature capable of increasing purified ice production by up to 40 percent for a 24-hour period.

Six adjustable refrigerator shelves

The 42" over-and-under with French door is the only Sub-Zero with refrigerator shelving that is split into two columns for maxium flexibility. Line up two half-shelves to form a full-width shelf, or stagger their positions to customize storage for tall or short items.

Nano-coated spill-proof shelving

A microthin layer of coating applied to the sides of each modular shelf prevents spills from spreading — making cleanup a breeze.

Full-width deli compartment

A soft-close deli drawer that spans the width of the refrigerator's interior provides ample room for packages and trays of meats, cheeses and more. Plastic dividers can be arranged for extra organization, or removed altogether.
