Transporting temperature-sensitive goods like fresh produce, pharmaceuticals, or other chemicals is not just about logistics. It also requires careful risk management. Even minor temperature fluctuations can lead to spoiled cargo, lost revenue, or compromised safety. That is why maintaining reliable refrigeration throughout the entire travel is critical, especially during overland transport, where power sources are not always guaranteed.
Refrigerated containers, also known as reefers, are designed to regulate temperature, but they can’t operate independently as they require a consistent power source to stay operational. This is where generator sets or gensets do their work. By equipping mobile power during transit, they ensure cargo stays protected, no matter the route or mode of transportation.
What Is a Cargo Trailer?
A genset is a diesel-powered unit that supplies electricity to reefers during transport. Refrigerators rely on a steady 460V, 3-phase power supply to keep their cooling systems running.
Connecting a genset to a generator goes beyond mounting equipment. It is an essential component of what keeps the reefer operational on the road or in intermodal transit. When done right, this setup assures constant power and protects cargo throughout the journey.
The Benefits of Genset Integration with Intermodal Container Chassis
Integrating gensets into container chassis offers several practical benefits that support more efficient and flexible transport:
Types of Gensets for Container Chassis
Gensets come in two primary designs, each built to suit different mounting needs and transport conditions for maximum efficiency and durability. Choosing the right type depends on how often containers are traded, the level of durability required, and how the genset integrates with the during transit.
Clip-On Gensets
Clip-on gensets are often preferred for their portability and are ideal for fast-paced operations where containers frequently move between different chassis.
Undermount Gensets
Undermount gensets are designed for permanence and protection, which are better suited for long-haul operations where containers remain paired with their chassis.
How Do Gensets Integrate with Container Chassis for Reefers?
Securing gensets with container chassis is critical to ensuring that reefers function during transport. This approach is required for cold chain logistics, particularly in intermodal transits where constant energy sources may not always be available.
Here are the steps on how to connect gensets into the container chassis and how it influences the transit:
1. Mounting Gensets to the Chassis
The initial step involves physically attaching the genset to the container chassis. It must be properly connected to avoid tension or uneven load distribution. This ensures its stability throughout transport, even under harsh road conditions or handling.
Mounting gensets can be done in two ways, depending on the type used:
Clip-On Gensets:
Undermount Gensets:
2. Establishing Electrical Power Connection
Once mounted, the genset is connected to the reefer’s electrical system via a heavy-duty power cable and a standard 460V industrial-grade plug.
Before connecting, check both ends for corrosion, wear, or bent pins. Use cable hangers or ties to keep the cable secure and lower the risk of disconnection during transit.
3. Electrical Synchronization and Start Up
Upon linking the gensets, the reefer unit generates electricity at the appropriate voltage and frequency, typically 460V at 60 Hz. The reefer unit detects this incoming power, switches from standby to active mode, and starts to regulate its internal temperature.
Additional synchronization steps include:
4. Fuel and Fluid Level Checks
Before the chassis is cleared for transit, operators should examine the following:
Reviewing the fuel levels is necessary to make sure the chassis can work without interruption, particularly on long routes with limited refueling options. This checking should also be logged to sustain route planning and avoid unexpected shutdowns.
5. Pre-Trip Safety and Operational Inspection
A comprehensive safety check is also performed to scan the genset and reefer system for seamless operation and safety integration. This is usually done through:
