The backup power system of the refrigerated truck is the second refrigeration power source used when the vehicle engine is not working or fails. Through the backup power system of the external power supply, the compressor can also maintain the temperature in the car and keep the goods fresh. It can be used as a temporary refrigeration solution to solve some emergencies, and the refrigerated truck can also be used as a temporary cold storage.

The working principle of backup power for refrigerated trucks: the external power supply is used for the motor to work, the independent compressor is driven to work, and the circulating refrigerant is provided for the refrigeration unit to work, without the need for chassis engine transportation.

Installation location: generally installed next to the girder of the refrigerated truck. It can also be installed inside the trunk of a refrigerated vehicle.
