The Essential Role of Reefer Containers in Global Shipping

In today's globalized world, the role of DFIC's reefer containers cannot be overstated. These specialized shipping containers are designed to transport perishable goods such as food, medicine, and vaccines, ensuring their freshness and safety during long-distance transportation. Let's delve deeper into the intricacies of reefer containers and their indispensable value in the shipping industry.

What Are Reefer Containers?

Reefer containers, short for refrigerated containers, are designed to maintain specific temperatures for the transportation of temperature-sensitive goods. These containers function like large-scale refrigerators, capable of maintaining temperatures ranging from -30°C to 30°C, depending on the cargo's requirements.

The Versatile Uses of Reefer Containers

  • Transporting Perishable Foods: Reefer containers are essential for shipping foods like frozen meat, seafood, fruits, vegetables, dairy products, juices, beverages, and even alcoholic beverages. Their ability to maintain consistent temperatures ensures the freshness and quality of these perishable goods.

  • Shipping Pharmaceuticals: During pandemics and other health crises, reefer containers play a critical role in transporting vaccines and medicines to remote locations. Their temperature-controlled environment ensures the efficacy of these sensitive drugs.

  • Transporting Dry Cargo (As Non-Operating Reefers): Even when the refrigeration unit is turned off, reefer containers can still be used to transport dry cargo, transforming into non-operating reefers. This flexibility allows shippers to maximize the utilization of their container fleet.

How Do Reefer Containers Work?

  • Maintaining Low Temperatures: The refrigeration unit in a reefer container continuously circulates cool air through the cargo, ensuring a constant temperature. However, it's important to note that reefer containers don't lower the temperature of the cargo; they maintain it. Therefore, it's crucial to pre-cool the cargo to the desired temperature before loading.

  • Power Supply from Generator Sets: Generator sets provide the necessary power to run the refrigeration unit, often connected to the ship's main power supply. For extra safety, many reefer containers are equipped with backup generator sets to ensure uninterrupted power supply during emergencies.

  • Ventilation for Freshness: Fruits and vegetables release heat, water, and carbon dioxide. Proper ventilation in reefer containers removes these gases, preventing premature ripening and maintaining the freshness of the produce. Different cargo stacking methods are used to optimize ventilation.

  • Maintaining Relative Humidity: Different cargo requires different humidity levels. Dehumidifiers in reefer containers help maintain the optimal humidity level, preventing condensation and mold growth. Data loggers, supported by remote modems, continuously monitor the temperature, humidity, and other critical parameters.

  • Drainage System for Excess Water: Reefer containers are equipped with a drainage system that removes any excess water accumulated inside the container, ensuring a dry and hygienic environment for the cargo.

In conclusion, reefer containers are invaluable assets in the shipping industry, enabling the safe and efficient transportation of temperature-sensitive goods worldwide. DFIC's commitment to providing high-quality reefer containers ensures that your cargo arrives at its destination in pristine condition.
