A refrigerated trailer, also known as a reefer trailer, is a specially designed vehicle used for transporting perishable goods such as food, pharmaceuticals, and other temperature-sensitive items. It is equipped with a refrigeration unit that regulates the temperature inside, keeping the cargo from spoiling or deteriorating during transport. In this article, we will discuss everything you need to know about refrigerated trailers.
The refrigeration system in a refrigerated trailer consists of a compressor, a condenser, an evaporator, and a refrigerant. The compressor is the heart of the system and is responsible for compressing the refrigerant gas, which increases its pressure and temperature. The condenser is located at the front of the trailer and is responsible for dissipating the heat from the refrigerant. The refrigerant then enters the evaporator, which is located inside the trailer, and cools the air within the trailer. The cool air is then circulated by fans throughout the trailer, keeping the cargo at a consistent temperature.
One of the most significant advantages of a refrigerated trailer is that it allows businesses to transport perishable goods over long distances. With a properly functioning refrigeration system, the cargo can be kept at a consistent temperature throughout the journey, ensuring that it arrives in good condition. This is particularly essential for businesses that transport temperature-sensitive goods such as fresh produce, meat, dairy products, and pharmaceuticals.
Another benefit of a refrigerated trailer is that it has a high level of insulation, which helps to maintain the temperature inside. The insulation usually consists of foamed-in-place polyurethane or polystyrene foam and is sandwiched between the inner and outer walls of the trailer. This insulation also helps to reduce heat transfer between the inside and outside of the trailer, making it more energy-efficient.
A refrigerated trailer can be powered by various sources, including diesel engine, battery, or electric standby. A diesel-powered trailer uses a diesel engine to power the refrigeration system, while a battery-powered trailer uses a battery pack to provide the power. In contrast, an electric standby trailer is plugged into an external power source, such as a generator, to power the refrigeration system. The choice of power source depends on various factors such as the distance and duration of the journey and the availability of power sources.
Like any other vehicle, a refrigerated trailer requires regular maintenance to keep it in good working condition. Some of the maintenance tasks that need to be performed include checking the refrigerant levels, inspecting the compressor and condenser, and cleaning or replacing the air filters. It is essential to follow the manufacturer’s recommended maintenance schedule to ensure that the refrigeration system is functioning correctly and to avoid costly repairs.
When selecting a refrigerated trailer, it is essential to consider various factors such as the size and weight of the cargo, the distance and duration of the journey, and the temperature requirements of the cargo. The size and weight of the cargo determine the size of the trailer and the type of refrigeration system required. The distance and duration of the journey determine the power source used, while the temperature requirements of the cargo determine the type of refrigeration system and its temperature range.
In conclusion, a refrigerated trailer is an essential tool for businesses that transport perishable goods over long distances. Its refrigeration system and insulation allow for the transportation of temperature-sensitive items, ensuring that they arrive at their destination in good condition. Regular maintenance and proper selection of the trailer are essential to keep it in good working condition and ensure the safe transport of the cargo.
If you’re in need of a refrigerated trailer, contact a reputable manufacturer or supplier who can help you choose the right trailer for your specific needs. Remember to consider all the factors mentioned above to ensure that you make the right choice. With a high-quality refrigerated trailer, you can transport your perishable goods with peace of mind and confidence.
