The Facets of Freshness

Since the 1950s, Sub-Zero has become an institution when it comes to keeping food fresh and healthy

Optimum preservation conditions for each type of food, without any hint of flavor transfer between the refrigerator and the freezer s an integral part of our lives that provides both pleasure and nourishment, food deserves careful handling. Cold air isn’t enough to maintain optimal freshness: Factors such as temperature consistency, humidity, and purified air all come into play in preserving the freshness of food.

All refrigerators are designed for cold storage, but Sub- Zero takes this detail further with a thermostat that users can set themselves. Once set, its microprocessor then keeps the temperature consistent within 1 degree of your chosen temperature setpoint. The refrigerator door’s magnetic seal also lessens work on the compressors and cuts energy costs by effectively keeping the cold air in.

The refrigerator and freezer in a Sub- Zero does not share air, ensuring that the salad and vegetables you store in a refrigerator remain humid and fresh while frozen meats in the freezer remain ice-cold and dry. Sub- Zero maintains separate, sealed compartments, ensuring air between the refrigerator and freezer does not mix.

Its antimicrobial air purification system, adapted from NASA technology, scrubs the air clean of ethylene gas every 20 minutes. Ethylene gas is emitted by some foods, like apples, which can cause other produce to spoil faster. Contaminants such as bacteria, mold, and viruses too small for traditional charcoal filters are also removed by this sophisticated air cleaner.

With 70 years of tradition and innovation, Sub-Zero sets the standard for freshness, serving the needs of the most discerning individuals around the globe. The pillars of food freshness and preservation— temperature, humidity, and purified air—are never compromised in any Sub-Zero refrigerator.
