Trailer technology keeps the summer from sizzling reefer loads
Transporting perishable foods like seafood in summer, even on reefer (refrigerated) trailers, is challenging because they spoil quickly. If food arrives at the wrong temperature or damaged, it can be rejected—costing of thousands of dollars. Fortunately, some newer, more affordable technologies can help reduce these losses and meet customer expectations.
Before using these technologies, carriers should have a strong inspection and maintenance program in place. Once that’s ready, here are three key technologies to consider:
1. Refrigerated trailer telematics
Reefer trailers often have telematics to monitor and control trailer conditions remotely. This helps ensure food safety and quality. With modern telematics, carriers can:
- Turn the refrigeration unit on/off or switch modes remotely.
- Provide proof of temperature during transit to reduce rejected loads.
- Meet customer and regulatory temperature monitoring requirements.
- Monitor fuel levels to avoid running out mid-trip.
- Cut maintenance and operating costs.
- Get alerts about issues before food is damaged.
2. Trailer tracking and sensors
Thanks to better batteries, sensors, and wireless technology, trailer tracking is more reliable and affordable. Sensors can show:
- Temperature inside the trailer.
- Trailer idle time and location.
- When doors are opened or closed.
- Whether the trailer is loaded or empty.
This data helps carriers:
- Charge for trailer use (demurrage) when used as storage.
- Find trailers faster and improve delivery times.
- Use equipment more efficiently.
- Track high-value shipments, even when not connected to a truck.
3. Cargo cameras
Since drivers can’t monitor cargo 24/7, cameras help fill the gap. They can:
- Catch cargo thieves in the act, showing who, where, and when.
- Show how full the trailer is after loading or partial unloading.
- Document cargo damage due to securement or temperature failures, trailer cleanliness, and leftover items like pallets or trash.
Key to remember: New technologies can help carriers improve food safety, reduce losses, and meet customer demands — giving them a competitive edge in the food transport industry.
