Transporting temperature-sensitive products can be a real headache for transport professionals. Fortunately, refrigerated trailers offer an ideal solution to meet this challenge. But what exactly is a refrigerated trailer? How does it work? How to use it? Immerse yourself in the fascinating world of refrigerated trailers.
A refrigerated trailer is specially designed to transport temperature-sensitive goods. These can be perishable foodstuffs, medicines, and other products that require precise temperature control. These trailers have a refrigeration or heating system to maintain the desired indoor temperature. An essential element in guaranteeing the quality and safety of the products transported, they are widely used in the transport and logistics industry.
There are a variety of refrigerated trailer models adapted to each specific need in your cold chain, such as:
The internal dimensions of a refrigerated semi-trailer are usually around 13,700 x 2,500 x 2,750 (L x W x H) millimeters, offering the capacity to load up to 33 pallets. In comparison, a refrigerated trailer of 500 kg has significantly smaller dimensions, i.e. approximately 1250 x 800 x 825 (L x W x H) millimeters, allowing the transport of approximately 800 liters of food on the road.
Refrigerated trailers are designed to transport products that may be damaged by temperature variations, whether high or low. Perishable foodstuffs are commonly carried in these trailers. However, they are not the only ones. Many other products also require temperature control. Examples:
Refrigerated trailers are not only used to maintain cool temperatures, they are also used to warm the air inside. So, in winter, shippers use them to protect heat-sensitive products from freezing.
The purpose of refrigerated trailers is to maintain the temperature of a product, rather than cooling it. The three main components of a refrigeration system are as follows:
The refrigeration process does not consist in introducing cold air, but rather in extracting heat from the air inside the trailer.
Variations in air pressure generate an air flow. As the air inside the trailer circulates over the evaporator, the heat is removed, and the now colder air is redistributed throughout the trailer.
The refrigerated trailer is equipped with a parking brake that you can activate using a lever that is usually located near the V drawbar junction of the chassis. But what are the steps for coupling the refrigerated trailer? How do you connect a fridge trailer?
Proper load distribution improves vehicle stability and, as a result, transport safety. Thus, for a diversified load, place heavy and resistant foodstuffs on the ground, without sticking them to the walls of the cell. This ensures better circulation of the cold inside the vehicle. It is important to note that a trailer with a refrigeration unit requires one or several hours to reach the desired temperature. It is therefore essential to connect it to a 220-volt electrical outlet well before loading food.
Familiarize yourself with the dimensions of the vehicle before driving your refrigerated trailer on the road. Also, remember that when backing up, the refrigerated trailer generally moves in the opposite direction to that of the steering wheels of your car.
To undock your refrigerated trailer safely, follow these steps:
To ensure the safety of the driver and the safety of the goods transported, you should regularly service and maintain your refrigerated trailer. Following these 5 tips will allow you to prevent problems and optimize the life of your equipment.
Frequent cleaning with hot water is recommended to maintain the cleanliness and hygiene of the structure. Avoid steam washing, which could damage sensitive trailer components. Remember to clean door seals and rails to ensure they work properly.
Before you hit the road, take the time to check the locking system, electrical equipment, parking brakes, and stands. These elements are essential to ensure safe transport.
Every week, examine the doors and the condition of the refrigeration cell for possible failures. A damaged joint or a poorly adjusted door could compromise the cold chain and affect the quality of the products transported.
Remember to periodically check chassis components and tires. A good chassis and well-inflated tires contribute to trailer stability and safer driving.
Finally, schedule regular visits to a professional to carry out thorough checks and preventive maintenance operations. This will help you detect potential problems before they become serious and costly.By paying close attention to the care and maintenance of your refrigerated trailer, you will not only ensure safety on the road, but also the quality and freshness of the products you transport. A wise investment to maintain your reputation and the satisfaction of your customers.
Complying with current regulations and standards for refrigerated trailers is crucial to ensure the safety and quality of the products transported. In this section, we'll discuss the key regulations and standards you need to pay attention to to stay compliant and protect your business.
Refrigerated trailers must comply with ATP standards (Agreement Relating to the International Transport of Perishable Goods), which define the temperature and insulation quality requirements for the transport of perishable products. These standards guarantee the quality and freshness of foodstuffs throughout the cold chain.
Make sure that your fridge trailer complies with local and national weight and size regulations. Limits vary by country, so it's important to check the regulations in force in the areas where you operate.
Refrigerated trailers are subject to periodic technical inspections to verify their compliance with safety and maintenance standards. Schedule these checks regularly to avoid penalties and operational issues.
Drivers of vehicles equipped with refrigerated trailers must have the skills and qualifications required to drive safely. Make sure your staff is trained and aware of current regulations.
Finally, refrigerated trailers must also comply with current environmental standards, in particular with regard to greenhouse gas emissions and noise levels. Consider these standards when buying and maintaining your equipment.
