Come to RC Willey for the 36 inch Sub Zero refrigerator. This bottom freezer refrigerator is based on technology pioneered by Sub-Zero that 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 providing optimum preservation conditions for each type of food. Many fresh foods emit ethylene gas, a naturally-occurring compound that hastens food ripening and spoilage. Sub-Zero refrigerators come with an air purification system (based on technology developed by NASA) that scrubs the air of ethylene and odor every 20 minutes. With Dual refrigeration, fresh foods thrive in a humid yet chilly climate, while frozen and convenience foods get the dry, frigid air they need. Why Sub-Zero? 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 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. 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 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. Worry-Free Warranty Sub-Zero offers an industry-leading full two-year warranty on appliances, along with a full five-year sealed system warranty and a limited twelve-year sealed system warranty.
