With the dual-voltage system, a reefer can run on 220V in addition to three-phase power. This makes the refrigerated container more flexible for use in locations where a 3-phase power connection is not available, such as construction sites, events, temporary storage locations, or business premises.

This option is pre-installed and makes it easier to use a reefer with a standard 220V power supply. Ideal when the container is used as mobile refrigeration or freezer storage and the available power supply is limited.
