The most unique container on the list is the reefer or refrigerated container. As the name suggests, this container has a refrigeration system that is linked to the power supply of the cargo ship. The reefer container aims to preserve temperature-sensitive goods such as dairy products, meat, fish, fruits and vegetables, etc.
What Is A Reefer Container?
Reefer containers are bottom air delivery systems that transport chilled air from the floor via particular T-shaped decking, with the benefit of providing a continuous and uniform flow of air across the whole cargo, powerful enough to provide flawless air exchange with the products.
What Are The Sizes?
Let's see reefer container sizes, dimensions, and specifications. ISO is the one that gives the standard dimensions and sizes but differs across manufacturers.
20FT Reefer
| Inside Length | Inside Width | Inside Height | Door Width | Door Height |
| 17‘8“ | 7‘5“ | 7‘0“ | 7‘5“ | 7‘3“ |
| 5.450 m | 2.285 m | 2.160 m | 2.290 m | 2.225 m |

What Is The Allowed Content Weight?
The tare weight, gross weight, and payload are the three primary weights. When the container is in service or before it is repainted for another application, these are painted on the outside of the container doors.
The container tare weight is the container's weight without freight or contents. The container's gross weight is the weight of the container plus the maximum payload it can hold, i.e. the container's maximum total weight.
| Measure | 20FT Container |
| Tare Weight | 2,950 Kgs |
| Max Gross Weight | 27,500 Kgs |
| Pay Load (Net Weight) | 27 m³ |
| Measure | 40FT Container |
| Tare Weight | 4,600 Kgs |
| Max Gross Weigh | 29,500 Kgs |
| Pay Load (Net Weight) | 67 m³ |
Why Should You Use A Reefer Container?
As the countries went into lockdown, reefer containers allowed food, medicines, and vaccinations to be shipped wherever they were needed. Reefers are unquestionably one of the most essential container types available, having been designed to transport such temperature-sensitive products and goods.
A reefer container, despite its name, is not designed to transport dry goods but you'd be amazed at how frequently reefers move dry goods too. To conclude, simply turn off the refrigerator unit! Your reefer container has been converted into a regular dry container.
What Are The Advantages?
The reefer container is monitored by a controller at least twice a day. Checking its functionality and status - temperature, humidity, and atmosphere are vital for maintaining the condition of the products. He is the one who is responsible for the overall safety of the products.
Furthermore, the controller must always be aware of the container's ventilation, temperature, drainage, and humidity. When neglected, this would result in products' quality and freshness.

What Are The Disadvantages?
However, reefers work on strict deadlines that might be difficult to meet due to perishable product time constraints. When paired with fewer cars, this might lead to challenging reefer scheduling limitations. It may also be challenging to maintain a constant temperature throughout a lengthy journey.
How Can Reefer Containers Benefit You Compared To Other Containers?
General cargo containers are highly handy when transporting consumer items that do not require specific conditions. However, some items need specific handling. If you move fresh fruits with general cargo containers from one nation to another, the cargo turns into waste and loses its economic worth during transportation. As a result, you must send perishable items in refrigerated or reefer containers.
What Are The Results Of Reefer Container Shipping Compared To Airfreight?
Shipping through ocean freight to carry things that must be kept at a specific temperature is particularly dangerous since there are multiple important points in the logistics chain that compromise the cold chain. From loading at the point of origin to awaiting loading on the runway, time in the hold, or waiting time in a warehouse, there are numerous external threats to the temperature of the product that require specialist treatment by an expert perishable cargo freight forwarder.
Because of their short shelf life or the unavailability of refrigerated or frozen shipping groupage or full reefer shipment alternatives, air freight is the only choice for some perishable consignments.
Conclusion
To fully reap these benefits, it is vital to ensure that reefer cargo stowage is done correctly. This is especially important for cold-treatment shipments since some fruit kinds may be denied at the destination country if they are not properly maintained due to the risk of pathogens still present. To avoid this, several standard reefer containers "Dos and Don’ts" must be followed.
