November 25, 20230

Reefer containers, short for refrigerated containers, play a vital role in the transportation and storage of temperature-sensitive goods. These containers provide a controlled environment that safeguards perishable items, ensuring their freshness and quality throughout the supply chain. At Safewater Lines, we understand the critical role reefer containers play in preserving product quality and ensuring food safety throughout the supply chain. In this comprehensive guide, we will have a look into the reefer containers, their features, factors affecting their performance, and best practices for maximizing their effectiveness.

Here are key reasons why reefer containers are vital:

  • For Preserving product quality and freshness.
  • Ensuring food safety and regulatory compliance.
  • Facilitating global trade and market expansion.
  • Minimizing product losses and waste.
  • Supporting the pharmaceutical industry’s temperature-sensitive cargo.
  • Extending the availability of seasonal goods.
  • Enabling the transportation of perishable goods over long distances.


Types of containers-

Following are the 3 types of containers-

  • General Container: 

This is a standard shipping container designed for general temperature controlled cargo. Majority of the business is moved in this container where the cargo temperature is ranging from -30 degrees to +30 degrees

  • Controlled Atmosphere: 

This type of container is equipped with technology that allows the regulation of the internal atmosphere. It is commonly used for transporting fruits like Bananas & Pineapples. The controlled atmosphere helps extend the shelf life of the goods by managing factors such as oxygen, carbon dioxide, and Nitrogen level inside the container.

  • Super Freezer: 

A super freezer container is designed to maintain extremely low temperatures, often well below freezing. This is ideal for transporting goods that require ultra-cold storage, such as certain types of seafood or medical supplies.


Features of Reefers-

  1. Temperature Control System: Reefer containers are equipped with advanced temperature control systems to maintain a specific temperature range for the transported goods.
  2. Humidity Control System: These containers also feature humidity control systems to regulate and maintain the desired level of humidity inside the container.
  3. Air Ventilation System: Reefer containers are designed with an efficient air ventilation system to ensure proper airflow and circulation of fresh air within the container.
  4. Door Design: The door design of reefer containers is engineered to provide a tight seal and prevent any temperature fluctuations or outside air from entering the container.
  5. Interior Liner: Reefer containers have interior liners made from materials such as stainless steel or aluminium, which are easy to clean and provide a hygienic environment for the cargo.
  6. Floor Design: The floor design of reefer containers is made with non-slip materials to ensure the safe and secure transportation of goods.


Factors Affecting Reefer Container Performance:

  1. Loading and Unloading Process: Proper handling during the loading and unloading process is crucial to maintaining the integrity of the cargo and the container’s temperature control system.
  2. Container Maintenance: Regular maintenance and servicing of reefer containers, including cleaning, inspection, and calibration of temperature control systems, play a vital role in ensuring optimal performance.
  3. Power Supply: Continuous and reliable power supply is essential to maintain the temperature and other control systems of reefer containers during transportation.
  4. Weather Conditions: External weather conditions, such as ambient temperature and humidity levels, can impact the performance of reefer containers. Proper insulation and control systems help mitigate these effects and maintain the desired cargo conditions.
