# What does Genset (reefer) mean in logistics?

Short answer

A diesel generator that powers a refrigerated container’s cooling unit when the container is not plugged into shore or ship power, mounted on the container (clip-on) or under the trailer chassis (underslung).

Needed for reefer containers moving by road between Indian ports, ICDs and customer premises. Genset fuel level and fault alarms should be checked before dispatch, because a genset failure on a long road leg is a common cause of excursions. Ask our desk how this applies to your consignment.
