Frequently Asked Questions

What is the difference between a walk-in freezer and a walk-in cooler?

A walk-in cooler maintains temperatures typically between 35°F–41°F for refrigerated storage, while a walk-in freezer operates at 0°F or below for frozen storage. Freezers require more insulation thickness, heated door frames to prevent frost buildup, and higher-capacity refrigeration units. Many box configurations, like the 8x8x8, are dual-purpose and can be set up for either application.
