A large portion of the trucking business involves hauling perishable cargo. That means having the perfect reefer container temperature range is essential to getting your load to its destination safely. If you’re new to truck driving or moving refrigerated cargo, read on to learn all about setting the right reefer temperature for different types of cargo, as well as best practices when working with perishable loads.

Reefer Temperature Range: The Cornerstone of Product Freshness

The reefer temperature range refers to the specific temperatures at which perishable goods need to be transported and stored to prevent spoilage, maintain their quality, and extend their shelf life. Controlling the temperature during transportation is essential to avoid potential losses due to spoilage, bacterial growth, and other factors that can compromise the integrity of the cargo.

Factors Influencing the Reefer Temperature Range

Several factors influence the optimal reefer temperature range for different types of cargo:

  • Product Type: Different goods have varying temperature requirements. For instance, frozen foods necessitate lower temperatures than fresh fruits.
  • Temperature Sensitivity: Some products are highly sensitive to temperature fluctuations, demanding tighter control over the reefer container’s environment.
  • Duration of Transit: Longer transit times might require adjustments to the reefer temperature range to ensure freshness upon arrival.
  • External Climate: The ambient temperature and weather conditions in the departure, transit, and destination regions influence the container’s temperature settings.

The Ideal Reefer Temperature Range for Various Goods

Maintaining the right reefer temperature range is essential for different categories of perishable items:

  1. Frozen Foods: -20°C to -25°C (-4°F to -13°F)
  2. Chilled Foods: 0°C to 4°C (32°F to 39°F)
  3. Fresh Produce: 5°C to 10°C (41°F to 50°F)
  4. Pharmaceuticals: As specified by the manufacturer (typically between 2°C to 8°C or 36°F to 46°F)

It’s crucial to note that adhering to these temperature ranges ensures that goods remain safe for consumption and maintain their desired quality.

Best Practices for Maintaining Reefer Temperature Range

Regular Monitoring and Calibration

Consistently monitor and calibrate the reefer container’s temperature to ensure it stays within the specified range. Modern reefer containers often come equipped with advanced sensors and automated temperature control systems.

Pre-cooling Procedures

Before loading perishable cargo, pre-cool the reefer container to the appropriate temperature. This practice prevents temperature fluctuations and ensures a stable environment during transit.

Proper Loading and Air Circulation

Arrange cargo in a way that allows proper airflow within the container. Adequate air circulation prevents temperature inconsistencies and promotes uniform cooling.

Monitoring During Transit

Use real-time tracking and monitoring systems to keep a close eye on temperature changes. These systems can send alerts if the temperature goes outside the desired reefer temperature range.

Emergency Protocols

Equip your cargo with backup power sources and temperature alarms. These measures can help mitigate temperature deviations in case of unexpected power outages or mechanical failures.
