Determining how many pallets can fit in a 40ft reefer container involves several factors, including the size of the pallets and the need for proper air circulation within the container. Here is a detailed explanation based on industry standards and container specifications:

40ft Reefer Container Dimensions

A 40ft reefer container has the following internal dimensions:

• Length: 37 feet (11.28 meters)

• Width: 7.48 feet (2.28 meters)

• Height: 7.38 feet (2.25 meters) These dimensions provide a load capacity of approximately 2,013 to 2,366 cubic feet, which allows for the transportation of large volumes of refrigerated products.

Standard Pallet Sizes

The most commonly used pallet sizes in international shipping are the EU pallet (1.2 x 0.8 meters) and the EUR2 pallet (1.2 x 1.0 meters). The number of pallets that can fit in a container depends on these dimensions and how they are arranged to ensure adequate ventilation.

Pallet Capacity in a 40ft Reefer Container

• European Standard Size Pallets (1200 mm x 800 mm): A 40ft reefer container can hold approximately 20 to 25 European standard size pallets. This capacity depends on how the pallets are distributed to ensure adequate ventilation and prevent cold loss.

• Standard Pallets (1.2 x 1.0 meters): If using standard pallets, a 40ft container can accommodate up to 21 pallets. This configuration optimizes space usage while allowing for necessary air circulation.

Factors Affecting Pallet Capacity

1. Air Circulation: 40ft Reefer containers require space for air to circulate around the goods to maintain the desired temperature. This need for ventilation can reduce the number of pallets that can be loaded.

2. Pallet Type and Size: The size of the pallets significantly affects how many can fit in the container. Smaller pallets allow for more units, while larger pallets reduce the overall capacity.

3. Loading Efficiency: The way pallets are loaded and stacked can also impact the total number that can fit. Proper loading techniques ensure maximum utilization of space without compromising air flow.

Industry Standards and Practices

The shipping industry has established standards for loading pallets into containers to ensure efficiency and product safety. These standards take into account the dimensions of the container and the pallets, as well as the need for temperature control and air circulation.

In summary, a 40ft reefer container can typically hold between 20 to 25 European standard size pallets, depending on the specific arrangement and the need for air circulation. The exact number may vary based on the pallet size, the type of goods being shipped, and the specific requirements for temperature control and ventilation within the container.
