How Long Does a Commercial Fridge Stay Cold Without Power?

What is the difference between commercial and ordinary fridge?

An ordinary fridge has shelves and a freezer. It can have a maximum of three doors. A commercial fridge can have a hard or glass top, a vertical or deep freezer, pastry cabinets, and more.

Under restrictive usage, a commercial fridge can stay cold without power for up to 6 hours. However, the household fridge can keep cold for up to 4 hours if power runs out. Opening the doors frequently reduces the timeline.

Full freezers, household or commercial, can stay cold for up to 48 hours if doors remain closed. But, if it is a half-freezer, the safe temperature lasts up to 12 hours.
