Sub-zero Over-and-Under Refrigerator 36” BI-36U/S

Sub-Zero’s pioneering technology features dual cooling systems, ensuring fresh food remains fresher for longer within the refrigerator’s cool, moist air. Simultaneously, the freezer’s frigid, dry air prevents frost and freezer burn, providing optimal preservation conditions for various food types. Many fresh foods produce ethylene gas, a natural compound that accelerates ripening and spoilage. Sub-Zero refrigerators are equipped with an air purification system, based on NASA-developed technology, that filters the air of ethylene and odor every 20 minutes. The refrigerator’s microprocessor maintains the interior temperature within one degree of its setpoint, and an advanced air seal around the door prevents leaks while saving energy. Constructed with premium-grade materials, Sub-Zero products are designed to last at least 20 years. Major components undergo extreme stress tests before being included in the final design, and every significant function is tested before shipping.

Sub-Zero’s Innovative Cooling Technology

Sub-Zero, a pioneer in the field of refrigeration technology, has introduced an innovative feature that incorporates two separate cooling systems. This unique system ensures that fresh food retains its freshness for longer periods due to the cool, moist air in the refrigerator. Simultaneously, the freezer section maintains a frigid, dry environment that effectively prevents frost and freezer burn. This dual system provides optimum preservation conditions tailored for each type of food.

Advanced Features for Food Preservation

Many fresh food items emit ethylene gas, a naturally-occurring compound that accelerates the ripening and spoiling process. To combat this, Sub-Zero refrigerators are equipped with an air purification system. This system, based on technology developed by NASA, scrubs the air of ethylene and odor every 20 minutes, thereby significantly reducing food spoilage.

Microprocessor Control and Energy Efficiency

Sub-Zero’s refrigerators also feature a microprocessor that controls the interior temperature to within one degree of its setpoint. An advanced air seal surrounding all four sides of the door prevents leaks, ensuring the refrigerator’s energy efficiency.

Quality and Durability

Built with premium-grade materials, Sub-Zero products are designed to withstand the test of time, lasting a minimum of 20 years. Major components undergo extreme stress tests before being incorporated into the final design. Furthermore, every major function is rigorously tested before shipping to ensure the highest quality and reliability.
