The transportation of temperature-sensitive products, such as food, pharmaceuticals, and chemicals, requires maintaining the correct temperature as a critical part of product safety and quality management. Even if a truck’s refrigeration unit is functioning properly from a technical standpoint, the temperature inside the trailer or container may not be distributed evenly throughout the entire cargo space. For this reason, temperature mapping is conducted to determine the actual temperature behavior of the container under various operating conditions. Temperature mapping provides valuable data for the transport company and gives customers greater confidence in the reliability of the transportation process.

 
What does temperature mapping mean?

Temperature mapping is a measurement process in which multiple temperature data loggers or sensors are placed at different locations within the cargo space. The measurements provide a comprehensive picture of the temperature distribution throughout the container.

The objectives of temperature mapping are to:: 

• Ensure that the temperature remains within the required limits throughout the transportation process.

• Verify the performance and effectiveness of the refrigeration system.

• Provide documented evidence for regulatory authorities and customers.

• Improve loading practices and transportation processes.

• Identify potential leakage points or temperature deviations.

• Ensure the quality and integrity of transportation operations

Temperature variations within the cargo space can occur due to factors such as the structural design of the load compartment, uneven air circulation, the opening and closing of doors, external weather conditions, and suboptimal cargo placement. Even a deviation of just a few degrees can have a significant impact on product quality and shelf life. For example, in the pharmaceutical industry, temperature excursions may reduce the efficacy of a product, while in the food industry they can increase microbiological risks.

 Temperature Measurement

Temperature data loggers continuously record the temperature within the cargo space, providing real-time monitoring. This enables a continuous and comprehensive analysis for temperature mapping. During a temperature mapping study, various measurements and test scenarios are performed, including:

• Temperature measurements throughout the cargo space.
• Tests with both partial and full loads under different temperature set points and limits.
• Measurements conducted during different seasons of the year.
• Door-opening simulations to assess the impact of loading and unloading operations on temperature stability.

 
A report is prepared based on the results, including the measurement setup, locations of the measurement points, temperature profiles, and conclusions.

Temperature mapping of a truck trailer or container is an important method for ensuring the safe and high-quality transportation of temperature-sensitive products. Through these measurements, it is possible to determine the temperature distribution within the cargo area, identify potential risk zones, and verify that products remain within the required temperature conditions throughout the entire transport process.

Regular temperature mapping supports quality management, reduces risks, and enhances customer confidence in the reliability and consistency of transportation services.

We have conducted temperature mapping of temperature-controlled transport vehicles to ensure the consistency and compliance of transport conditions. The measurements were used to evaluate temperature distribution throughout different areas of the cargo space and to verify that the required temperature is maintained uniformly across the entire transport compartment. The results of the mapping are utilized for the development of transport processes, quality management, and the preparation of documentation required by customers and regulatory authorities.
