20-foot refrigerated container, often abbreviated as a 20ft reefer container, is a specialized shipping container designed for transporting goods that require temperature-controlled environments. These containers are essential for shipping perishable items such as food products, pharmaceuticals, and other temperature-sensitive goods over long distances. Here’s an overview of a 20ft refrigerated container, its features, and its applications:

Features and Specifications:

1. Dimensions:
   • A standard 20ft refrigerated container has external dimensions of approximately 20 feet in length (6.1 meters), 8 feet in width (2.44 meters), and 8.5 feet in height (2.59 meters). Internal dimensions are slightly smaller due to insulation and refrigeration unit components.
2. Temperature Control:
   • Refrigeration Unit: Integrated with a built-in refrigeration system that regulates the temperature inside the container. The unit can maintain temperatures ranging from -25°C to +25°C (-13°F to +77°F), depending on the specific model and requirements.
   • Thermal Insulation: Designed with thick insulation layers (typically polyurethane foam) to minimize heat transfer and maintain consistent temperatures, even in varying environmental conditions during transportation.
3. Power Supply:
   • Reefer containers are equipped with electrical connections to power the refrigeration unit. They can operate on standard electrical power sources (such as 380-460V AC, 3-phase) or with diesel-powered generators when on the move or in locations without direct electrical supply.
4. Construction:
   • Steel Frame: Like standard shipping containers, reefer containers have a robust steel frame for durability and structural integrity.
   • Corrosion Resistance: Exterior surfaces are often coated with corrosion-resistant paints or treatments to withstand marine environments and outdoor conditions.
5. Control Systems:
   • Temperature Monitoring: Advanced reefer containers are equipped with digital control panels that allow operators to monitor and adjust temperature settings remotely. This ensures precise temperature management throughout the journey.
   • Humidity Control: Some models include humidity control features to maintain optimal conditions for certain types of cargo, such as fresh produce or pharmaceuticals.
6. Security:
   • Reefer containers are equipped with standard locking mechanisms and security features to prevent unauthorized access and protect valuable cargo during transit.

Applications:

• Food Industry: Used for transporting fresh fruits, vegetables, dairy products, meat, fish, and other perishable foods across global supply chains.
• Pharmaceuticals: Ideal for transporting vaccines, medicines, and other temperature-sensitive pharmaceutical products that require strict temperature control.
• Biotechnology: Used for transporting biological samples and research materials that require stable and controlled environmental conditions.
• Chemicals: Transporting chemicals and hazardous materials that require specific temperature ranges to maintain safety and integrity.

Benefits:

• Preservation of Quality: Ensures that perishable goods arrive at their destination in optimal condition, minimizing spoilage and waste.
• Global Reach: Facilitates international trade by enabling the transportation of temperature-sensitive goods across long distances.
• Flexibility: Can be used for both intermodal transportation (sea, rail, and road) and stationary storage at ports, warehouses, and distribution centers.
