ENERGY STAR® Qualified
You can keep your food fresher longer with this 48 inch Sub-Zero built-in side by side refrigerator from RC Willey. Wrinkled fruit, wilted lettuce? You’ve seen your share of past due, even spoiled food in the refrigerator. Well, it doesn’t have to be that way – this Sub-Zero built-in refrigerator keeps your food fresher longer with the most advanced food preservation technology available – a technology developed through almost 70 years of research. That means crisper greens, juicier peppers, and blueberries that burst with flavor – even weeks after you’ve brought them home from the market. You'll taste the difference.

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 monitors each section of your Sub-Zero for pinpoint climate control. Storage capacity is a generous 19.1 cu. ft. refrigerator and an 9.8 cu. ft. freezer. Bottom line? More flavorful, delicious food for you, your family, and your guests.

Why Sub-Zero?

Dual Refrigeration

Dual Refrigeration = Optimal Humidity

Technology pioneered by Sub-Zero features two separate cooling systems so fresh food stays fresher longer in the cool, moist air of the refrigerator. Frigid, dry air prevents frost and freezer burn in the freezer–optimum preservation conditions for each type of food.

Advanced Temperature control

Advanced Temperature Control

Sub-Zero’s microprocessor controls the interior temperature to within one degree of its setpoint. An advanced air seal around all four sides of the door prevents leaks while conserving energy.

Refrigerator Clean Air Purifier

Air Purification System Fights Spoilage, Odors

Many fresh foods emit ethylene gas, a natural compound that hastens spoilage. Sub-Zero's 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.

Rigorous Testing

Rigorous Testing

Built with premium-grade materials, Sub-Zero products are designed to last a minimum of 20 years. Major components are subjected to extreme stress tests prior to going into the final design, and every major function is tested before shipping.
