Sub-Zero, Inc. introduced a new Built-In Refrigeration Series that the company says will help reduce food waste and keep food fresher longer. The refrigerator has a freshness preservation system, which is a dual-compressor operating system that separately controls the temperature and humidity of the refrigerator and freezer compartments, and holds preset temperatures within a plus-or-minus 1-degree. This independent control of the refrigerator and freezer compartments reportedly ensures high air quality and therefore, fresh food and energy efficiency.
The refrigerator also includes an air purification system that "scrubs" the entire volume of air in the refrigerator an average of once every 20 minutes to reduce odors, viruses and bacteria, as well as the ethylene gases present in some foods that cause premature ripening and, ultimately, food spoilage.
