Your Position: Home - Transportation - The Difference Between a Reefer And an Insulated Container

The Difference Between a Reefer And an Insulated Container

The difference between the two vessel types is simple. Reefers have a motor that requires a power source like the generator on board. On the other hand, a non-refrigerated container relies on the same characteristics as a reefer. It is a large insulated container that maintains a stable temperature, but does not have an active refrigeration system.


When choosing between a refrigerated container and an insulated container, it is important to understand the needs of the product being transported. Reefer containers provide precise temperature control within the container. Insulated containers simply maintain the initial temperature and protect the interior from external conditions. Reefer containers are used for climate-controlled storage and to keep goods refrigerated, frozen or at a specific temperature during long-distance shipments. Insulated containers are commonly used in the retail market.

A clear example of the use of refrigerated containers is the shipment of seafood from South India to Europe. Maintaining the cold chain of this frozen and very sensitive product throughout the journey is critical. Specific temperatures are required to keep the seafood frozen and not spoil or contaminate it by thawing. The temperature unit remains the same throughout the journey.


When transporting products with a long shelf life (e.g. onions or potatoes), the insulated container is sufficient. It protects the cargo from external weather conditions and maintains a cool temperature during the journey. No specific temperature is required.


Insulated bulkheads are insulation layers used to separate cargo in trailers, truck bodies or vans. They allow you to create multiple temperature zones in one vehicle to optimize the climate for each type of cargo. You can also use bulkheads to reduce the area of the cooling space to get a smaller cooling load for less energy consumption.


How to insulate shipping containers?

Insulation of standard containers for transportation purposes is a very complicated process. The most economical and hassle-free way to transport sensitive cargo is to simply purchase a special insulated container.


There are different options to insulate standard containers.


Two-layer walls

The walls of the container need to be covered by two layers of walls. This is evacuated to prevent the transfer of heat between the outside and the inside.


Additional inner layer

An additional layer is installed on the wooden frame. This layer is completely sealed to ensure that the interior remains condensation-free.


Well-aligned container walls

The container walls are aligned with the liner (a special structure built into the walls). Multiple layers of thermal blankets are also used.


Gas-filled chambers

A gas-filled chamber around the entire container seals in the heat and maintains a constant temperature inside.


To add such a structure to a standard container, it is recommended to consult a professional organization. This is especially true if the purpose of the container is to transport sensitive cargo. Insulation on a smaller scale can be accomplished manually by using insulation blankets around individual pallets. Smaller boxes with inflatable chambers can also be placed inside the container. Bubble wrap is also an effective solution for reduced insulation or temperature control.


Insulating standard containers for household use is much easier. This can be done manually using rigid foam, spray foam or rigid mineral wool.
