- The best choice depends on cargo needs, site conditions, storage duration, and mobility.
How Reefer Refrigerated Containers Work
Refrigerated shipping containers combine insulated walls with an integrated refrigeration system to protect temperature-sensitive cargo. The system removes heat from the container and maintains the selected temperature throughout storage or transport.
The basic process includes:
- Pre-cooling: Brings the container to the required temperature before loading.
- Loading: Position cargo to allow proper airflow.
- Cooling: Removes heat and maintains the set temperature.
- Monitoring: Tracks temperature and system performance.
- Power: Uses an external electrical power supply from a vessel, terminal, facility, or compatible generator.
Proper airflow is essential. Blocked vents or tightly packed cargo can restrict circulation and create uneven temperatures.
How Reefer Trailers Work
A reefer trailer combines an insulated cargo area with a dedicated refrigeration unit to keep temperature-sensitive products within the required range during transportation.
Its operation generally involves:
- Pre-cooling: Cools the trailer before loading.
- Cargo loading: Arranges products to support airflow.
- Temperature control: Maintains the required temperature during transit.
- Door management: Limits the entry of warm air into the trailer.
- Monitoring: Tracks temperature and refrigeration performance.
- Power: Typically uses a dedicated diesel engine to operate the refrigeration unit during travel or while parked.
Proper loading, airflow, monitoring, and routine maintenance help maintain stable temperatures and protect refrigerated cargo.
The key difference is simple: reefer containers support both stationary storage and transportation, while reefer trailers are built specifically for mobile temperature-controlled delivery.
