Maintaining the temperature inside a refrigerated truck is crucial for transporting perishable goods such as food, pharmaceuticals, and certain chemicals. As a refrigerated truck supplier, I understand the importance of this aspect and have gathered a wealth of knowledge and experience in ensuring that our trucks can provide a stable and appropriate temperature environment. In this blog, I'll share some effective ways to maintain the temperature inside a refrigerated truck.
Choose the Right Refrigerated Truck
The first step in maintaining the temperature is to select a suitable refrigerated truck. Different types of goods require different temperature ranges. For example, fresh produce usually needs a temperature between 2°C and 8°C, while frozen foods need to be kept at -18°C or lower.
We offer a variety of refrigerated trucks to meet different needs. The 13 Ton Refrigerated Truck is a great option for large - scale transportation. It is equipped with a high - performance refrigeration system that can maintain a consistent temperature even during long - distance hauls. Another option is the Feidie W7 Insulated Cargo Truck, which is more suitable for medium - sized loads. It has excellent insulation properties, reducing the heat exchange between the inside and outside of the truck. And the Dongfeng Tianjin KR Refrigerated Cargo Van is known for its reliability and energy - efficiency, making it a popular choice for many customers.


Regular Maintenance of the Refrigeration System
The refrigeration system is the heart of a refrigerated truck. Regular maintenance is essential to ensure its proper functioning.
- Clean the Condenser Coils: The condenser coils are responsible for releasing heat from the refrigeration system. Over time, dirt, dust, and debris can accumulate on the coils, reducing their efficiency. It is recommended to clean the condenser coils at least once a month. Use a soft brush or compressed air to remove the dirt gently.
- Check the Refrigerant Level: The refrigerant is the substance that absorbs and releases heat in the refrigeration system. A low refrigerant level can cause the system to work inefficiently or even break down. Check the refrigerant level regularly and refill it if necessary. However, this should be done by a professional technician to avoid any safety hazards.
- Inspect the Compressor: The compressor is the most important component of the refrigeration system. It compresses the refrigerant and circulates it through the system. Check the compressor for any signs of wear and tear, such as unusual noises or vibrations. If there are any problems, have the compressor repaired or replaced immediately.
Proper Loading and Unloading
The way you load and unload goods can also affect the temperature inside the refrigerated truck.
- Pre - cool the Truck: Before loading the goods, pre - cool the truck to the desired temperature. This helps to reduce the time it takes to cool the goods and ensures that they are stored at the right temperature from the start.
- Load the Goods Properly: When loading the goods, make sure there is enough space for air circulation. Do not over - pack the truck, as this can block the air vents and prevent the cold air from reaching all parts of the cargo area. Use pallets or racks to keep the goods off the floor and allow air to flow freely.
- Minimize the Door Opening Time: Every time the door of the refrigerated truck is opened, warm air enters the cargo area, which can cause the temperature to rise. Minimize the door opening time during loading and unloading. If possible, use a dock shelter or a curtain to reduce the amount of warm air that enters the truck.
Monitor the Temperature
Continuous temperature monitoring is crucial to ensure that the goods are being transported at the right temperature.
- Install a Temperature Monitoring System: A temperature monitoring system can provide real - time temperature data inside the refrigerated truck. It can also send alerts if the temperature goes out of the set range. There are different types of temperature monitoring systems available, such as wired and wireless systems. Choose a system that suits your needs and budget.
- Keep Records: Keep a record of the temperature readings during the transportation process. This can help you to identify any potential problems and take corrective actions if necessary. It also provides evidence that the goods have been transported at the right temperature, which is important for quality control and compliance.
Insulate the Truck
Good insulation can reduce the heat transfer between the inside and outside of the refrigerated truck, making it easier to maintain the temperature.
- Check the Insulation Material: The insulation material in the truck walls, floor, and ceiling plays a crucial role in reducing heat transfer. Check the insulation material regularly for any signs of damage or wear. If there are any holes or gaps, repair them immediately to prevent heat leakage.
- Seal the Doors and Windows: The doors and windows are the areas where the most heat transfer occurs. Make sure the doors and windows are properly sealed. Replace any worn - out gaskets or seals to ensure a tight fit.
Consider the External Environment
The external environment can have a significant impact on the temperature inside the refrigerated truck.
- Avoid Parking in Direct Sunlight: Parking the refrigerated truck in direct sunlight can cause the temperature inside the truck to rise quickly. Whenever possible, park the truck in a shaded area or use a sunshade to protect it from the sun.
- Be Aware of Temperature Changes: During long - distance hauls, the external temperature can change significantly. Be prepared for these changes and adjust the refrigeration system settings accordingly. For example, if the outside temperature is very high, you may need to increase the cooling capacity of the system.
In conclusion, maintaining the temperature inside a refrigerated truck requires a combination of proper equipment selection, regular maintenance, correct loading and unloading procedures, continuous temperature monitoring, good insulation, and consideration of the external environment. As a refrigerated truck supplier, we are committed to providing our customers with high - quality trucks and comprehensive support to help them maintain the temperature of their cargo effectively.
