Genset (Generator Set)
A genset, or generator set, is a portable power unit used to supply electricity to refrigerated containers (reefers) during transport. It ensures the container’s cooling system runs continuously, keeping temperature-sensitive goods, such as food, pharmaceuticals, or chemicals, at the required temperature. Gensets are essential when reefers move by truck, rail, or through areas where fixed power sources are not available.
There are two common types: clip-on gensets that attach directly to the reefer and underslung gensets mounted beneath a chassis or trailer. Both power the refrigeration unit independently, allowing cargo to stay protected throughout long journeys or during transit stops. Without a genset, the reefer cannot maintain temperature, leading to spoilage or quality loss.
Gensets are carefully monitored to ensure fuel levels, voltage output, and operating conditions remain stable. Logistics teams often perform pre-trip inspections to confirm the unit is working properly before departure. This avoids costly cargo damage and keeps cold chain shipments compliant with safety standards. Reliable genset use is crucial for uninterrupted temperature control.
Overall, gensets play a vital role in maintaining cold chain integrity during inland and multimodal moves. They provide uninterrupted power, safeguard sensitive cargo, and ensure temperature requirements are consistently met from origin to destination.
Frequently Asked Questions about Genset (Generator Set)
Clear answers to the most common questions people have when learning about Genset (Generator Set).
They provide continuous power to the reefer unit during transport, ensuring temperature-sensitive goods remain properly chilled or frozen.
Not always. They are used when reefers move through areas without a fixed electrical supply, such as during trucking, rail moves, or remote terminal operations.
Temperature inside the reefer can rise quickly, risking cargo spoilage. Regular checks, fuel monitoring, and proper maintenance are essential to prevent failures.
