There’s more to preservation then keeping food cold. Different foods require different storage procedures. That’s why, inside each refrigerator, you’ll find “freshness cards” that provide easy-to-follow tips for ensuring maximum food preservation.
Sub-Zero refrigeration products guard freshness by addressing the three pillars of food preservation: temperature control, proper humidity and purified air.
Sub-Zero’s microprocessor controls the interior temperature to within one degree of its set point. An advanced air seal around all four sides of the door prevents leaks while conserving energy.
To preserve flavor, fresh foods need chilly, humid air and frozen foods require frigid, dry air. Sub-Zero’s dual refrigeration creates separate, sealed systems for the refrigerator and freezer to ensure the optimal humidity for both.
NASA- Inspired Air Purification
Many fresh foods emit ethylene gas, a natural compound that hastens spoilage. Sub-Zero’s antimicrobial air purification system, inspired by NASA technology, scrubs the air of ethylene- along with odor-causing bacteria, mold and viruses- every 20 minutes.
