Types of 40 standard reefer container

A 40 standard reefer container is a shipping container with a built-in refrigeration system. It is used for transporting cargo over long distances while maintaining the required temperature. Generally, 40-foot containers are the largest and most commonly used containers in shipping. That said, here are the different types of 40 standard reefer containers.

• By temperature control method:

  These containers are classified according to their temperature control mechanism.

  Self-contained reefers: These are containers with their own refrigeration units. They are ideal for long-distance shipping. The refrigeration unit is powered by electricity from the ship's power supply or from generators on trucks and trains during intermodal transport.

  Plug-in reefers: These containers do not have refrigeration units. They are designed to be plugged into the ship's electrical system or a specialized truck or train's electrical system.

• By cargo type:

  These containers are also classified according to the type of cargo being transported.

  These containers can be used to transport foodstuffs like fruits, vegetables, meat, fish, and dairy products. They can also be used to transport pharmaceuticals and chemicals, which require strict temperature controls during transit.

• By design features:

  Some 40-foot standard reefer containers have design features that make them suitable for specific types of cargo. For instance, high-cube reefers are high 40-foot containers that offer extra vertical space for tall cargo. On the other hand, multi-temperature reefers have several compartments that allow for the simultaneous transport of goods requiring different temperature settings.

• By size and capacity:

  Standard 40-foot reefers have a length of about 12.19 meters. However, there are also high-capacity reefers with a larger internal volume, such as high-cube reefers, which are about one foot longer than standard 40-foot reefers.

Specifications and maintenance of 40 Standard Reefer containers

• Electrical Supply

  It is important to maintain a constant electrical supply to the reefer containers for uninterrupted temperature control. In case of power supply interruptions, there are backup power sources such as generators that can be utilized. Regular checks on the electrical connections are necessary to ensure there are no faulty or loose connections that could disrupt the power supply to the reefer.

• Temperature Monitoring and Control

  Temoperature inside the reefer container is continuously monitored and adjusted as needed using built-in temperature control systems. In case of temperature fluctuations or alarms, the underlying causes are promptly investigated and addressed to prevent any compliance or product spoilage.

• Sealing and Insulation

  The reefer containers are regularly inspected for any damages or wear to the seals and insulation. Damaged seals or insulation are promptly repaired or replaced to maintain the integrity of temperature control. Additionally, the containers are checked for any gaps, cracks, or air leaks that could compromise temperature stability and promptly addressed.

• Airflow Management

  The proper airflow inside the container is ensured by not obstructing the designated airflow paths and ensuring cargo is loaded in a manner that allows for adequate airflow around the products. The container is also checked for any fan or airflow system malfunctions, which are promptly addressed to maintain proper airflow and temperature control.

• Reefer Container Maintenance Schedule

  The maintenance schedule for reefer containers is adhered to, and all recommended maintenance activities are performed at the specified intervals. This includes inspections, cleaning, and servicing of the refrigeration unit, electrical system, and container structure. The container is also checked for any maintenance issues or required repairs, which are promptly addressed to ensure optimal performance and compliance of the reefer.

How to Choose 40 Standard Reefer Container

When choosing a 40-foot standard reefer container, consider the following factors:

• Capacity

  For a reefer container, cargo capacity refers to the maximum weight and volume of goods that can be transported. When selecting a reefer container, consider the shipping requirements and the type of cargo being shipped.

• Power Consumption

  40 standard reefers use power to keep cargo at the right temperature. Power usage is important, especially for long trips. When deciding on a reefer container, think about how much energy it will use based on the distance and route taken.

• Ease of Use

  Consider the container's accessibility, loading and unloading convenience, and cargo securing methods. Additionally, think about the ease of operating and controlling the refrigeration system.

• Cost

  While cost should not be the only factor, it is important to consider the initial purchase price, maintenance expenses, and operating costs. Finding a reefer container that meets budgetary constraints while fulfilling all requirements is essential.

How to DIY and Replace 40 Standard Reefer Container

To replace a 40-foot standard reefer container is not a DIY-friendly job. All the mentioned steps above must be undertaken by qualified personnel. However, here are some general guidelines on how to replace a 40-foot standard reefer container:

Once the container is loaded and the freight ready to be shipped, the following must be done to ensure a smooth replacement process:

• Consult with a qualified marine engineer or container modification specialist to develop a safe and effective plan for replacing the reefer container.
• Contact a licensed and certified container transport company to transport the container to the destination where the replacement will take place.
• Work with a team of qualified technicians and engineers to disassemble the old reefer container and remove it from the vessel.
• Install the new reefer container on the vessel according to the manufacturer's specifications and industry standards.
• Connect the new reefer container to the vessel's power and communication systems.
• Conduct thorough inspections and testing to ensure that the new reefer container is functioning properly and meets all safety and regulatory requirements.
• Once the container is loaded and the freight ready to be shipped, the following must be done to ensure a smooth replacement process:

Q&A

Q1: What is the difference between a 20-foot and a 40-foot reefer container?

A1: The primary difference between a 20-foot and a 40-foot reefer container is its size. A 40 standard reefer container is double the length of a 20-foot reefer container. As a result, a 40-foot container can hold more cargo than a 20-foot container. A 40-foot reefer container has a capacity of about 28 to 30 tons, while the 20-foot container has a capacity of 12 to 16 tons. The internal dimensions of a 40-foot reefer container are approximately 12.03 m x 2.35 m x 2.39 m, and the 20-foot container measures 5.91 m x 2.35 m x 2.39 m.

Q2: Can a 40-foot reefer container be used for non-perishable cargo?

A2: Yes, a 40-foot reefer container can be used to transport non-perishable goods. The temperature control and monitoring systems in a reefer container are designed to maintain specific conditions for sensitive cargo. This ensures that non-perishable goods remain in optimal conditions throughout the journey. Additionally, these containers provide an extra protective barrier against external elements, such as extreme weather.

Q3: How much power does a 40-foot reefer container require?

A3: The exact amount of power a 40-foot reefer container requires depends on the type of container and the equipment inside it. On average, a 40-foot reefer container uses between 3,000 and 6,000 kWh per year. This is equivalent to 250 to 500 kWh per month. The amount of energy used also depends on the temperature set inside the container and the cargo being transported.

Q4: How often should the refrigerated container be serviced?

A4: It is advisable to carry out maintenance and servicing of the reefer container every three to six months. However, the frequency may vary depending on how often the container is used and the conditions it is exposed to. Regular inspection and servicing of the reefer container are crucial to ensuring that all the equipment inside is working optimally. This also helps to prevent potential problems that could disrupt the cold chain.

Q5: Can a 40-foot high-cube reefer container be used for intermodal transport?

A5: Yes, a 40-foot high-cube reefer container is designed for intermodal transport. It can be easily transferred between ships, trucks, and trains without disturbing the cargo inside. This is made possible by its standardized dimensions, which meet international shipping regulations.
