Why Your Refrigerated Truck Isn't Reaching the Desired Temperature

Many refrigerated truck operators face the issue of their cooling systems not achieving the set temperature.

If your cooling unit seems to be running continuously without success, consider these key troubleshooting steps:

Check for Cooling Unit Malfunctions

First, ensure that the cooling unit is functioning properly. Common issues include refrigerant leaks, dirty condensers, or faulty fan motors. If any of these problems are present, visit a reputable repair shop for professional inspection and repair.

Evaluate Insulation and Sealing

If the cooling unit is working correctly, inspect the insulation and sealing of the refrigerated compartment. Look for any noticeable leaks or areas where cold air might be escaping.

Improving insulation can help the compartment maintain the desired temperature more effectively.

Avoid Obstructing the Evaporator

When loading the truck, make sure not to stack goods in front of the evaporator's outlet. Excessive or poorly arranged cargo can block air circulation, leading to ineffective cooling and difficulty reaching the set temperature.

Maintain Adequate Clearance Between Cargo and Roof

It's crucial to keep a minimum distance of 220 mm between the top of the cargo and the refrigerated compartment's ceiling. This clearance ensures that the air vents are not obstructed and helps maintain balanced airflow throughout the compartment.

Pro Tip: For optimal cooling performance, pre-chill the compartment 1-2 hours before loading. This simple step can significantly enhance the effectiveness of your cooling system.

By addressing these common issues, you can improve your refrigerated truck's cooling efficiency and ensure that your cargo remains at the right temperature.
