STORAGE

Keeping Food At Its Best

DUAL REFRIGERATION ®

This Sub-Zero features a unique Dual Refrigeration® system to keep food fresher longer.

With the Sub-Zero Dual Refrigeration® system, individual refrigerator and freezer systems have been designed to maintain accurate, consistent temperatures and proper humidity levels for longer food life expectancy. Dual Refrigeration® eliminates transfer of fresh food odors to frozen food and ice and does not freeze the moisture out of the air in the fresh food section.

For handy tips and information on how to maximize food freshness, refer to the freshness cards stored in the refrigerator.
