Understanding the Refrigerated Container (Reefer)
Refrigerated containers, commonly known as reefers, are specialized shipping containers designed to transport goods that require controlled temperatures. These containers play a crucial role in the logistics of perishable items such as food, pharmaceuticals, and other temperature-sensitive products. Let’s delve into the various aspects of reefers to understand their significance and functionality.
Reefers are available in different types, each tailored to specific temperature requirements. The two primary categories are mechanical reefers and non-mechanical reefers. Mechanical reefers are equipped with refrigeration units, while non-mechanical reefers rely on external cooling sources or insulation alone.
The cost of a reefer is generally higher than that of a standard container due to the advanced technology and insulation required. However, the benefits of using a reefer far outweigh the initial investment. These containers ensure that the goods remain fresh and safe throughout the transportation process.
Types of Refrigerated Containers
1. Mechanical Refrigerated Containers: These containers come with built-in refrigeration units that maintain the desired temperature. They are suitable for transporting goods that require precise temperature control, such as pharmaceuticals and frozen foods.2. Non-Mechanical Refrigerated Containers: These containers rely on insulation and external cooling sources to maintain the desired temperature. They are suitable for transporting goods that require less precise temperature control, such as some types of fresh produce.3. Insulated Refrigerated Containers: These containers are insulated to retain the temperature of the goods inside. They do not have a refrigeration unit and rely on external cooling sources or ambient temperature.4. Reefer Containers with External Refrigeration Units: These containers have refrigeration units mounted on the exterior. They are suitable for transporting goods that require precise temperature control and are often used for long-distance transportation.
The dimensions of a reefer are similar to those of a standard container, but the internal space is slightly smaller due to the insulation and refrigeration unit. The refrigeration unit is typically located at the front of the container, with a partition separating it from the cargo area.
Reefer Container Specifications
The specifications of a reefer container include the following:- External Dimensions: Length: 20 feet, 40 feet, or 45 feet; Width: 8 feet; Height: 8.5 feet or 9.5 feet.- Internal Dimensions: Length: 19 feet 10 inches, 39 feet 4 inches, or 44 feet 4 inches; Width: 7 feet 6 inches; Height: 7 feet 6 inches or 7 feet 10 inches.- Volume: 33 cubic meters, 67 cubic meters, or 101 cubic meters.- Refrigeration Capacity: Varies depending on the model and the type of goods being transported.
The temperature inside a reefer can be controlled using a thermostat. The ideal temperature for transporting apples, for example, is between 0-3 degrees Celsius, with a ventilation rate of 15 cubic meters per hour.
Reefer Container Technology
The technology behind reefers has evolved significantly over the years. Modern reefers are equipped with advanced features such as:- Temperature Monitoring: Real-time temperature monitoring using sensors and IoT technology.- Data Logging: Recording temperature and other relevant data for traceability and compliance purposes.- Remote Control: Controlling the reefer’s settings and monitoring its performance from a remote location.- Energy Efficiency: Advanced insulation and refrigeration systems that reduce energy consumption.
One notable example of reefer technology is the IBOX Reefer, a solution developed by andE Solutions and Shanghai Hailian Zhongtong Information Technology Co., Ltd. The IBOX Reefer integrates andE’s innovative software with Hailian Zhongtong’s IoT hardware and sensors. This solution ensures that cold chain goods are transported safely and efficiently, reducing risks and costs for carriers.
In conclusion, reefers are an essential component of the logistics industry, enabling the safe and efficient transportation of temperature-sensitive goods. With advancements in technology, reefers continue to evolve, offering improved performance, energy efficiency, and cost-effectiveness.
