A 20-foot refrigerated shipping container is a type of refrigerated container used for transporting perishable goods, such as fresh food, pharmaceuticals, temperature-sensitive chemicals, etc. These containers are also called refrigerated containers, reefer containers, or fridge containers.

The 20-foot refrigerated containers have the same external dimensions as the standard 20-foot containers, which are approximately 6.06 meters long and 2.44 meters wide. However, the interior height of refrigerated containers can vary slightly depending on the model, generally around 2.28 meters. They are equipped with a refrigeration system that maintains a constant temperature inside the container, generally between -25°C and +25°C, depending on the needs of the cargo.

The 20-foot refrigerated containers are made with insulating materials to maintain a stable temperature inside the container, even in the event of external temperature variations. They are equipped with special insulation panels, a ventilation and temperature control system, as well as an electrical power system for the operation of the refrigeration system.

20-foot refrigerated containers are commonly used in the food industry for the transportation of fruits, vegetables, meats, fish, dairy products, etc. They are also used in the pharmaceutical industry for the transport of temperature-sensitive medications and chemicals.

Due to their ability to maintain a stable temperature inside the container, 20-foot refrigerated containers are an ideal solution for transporting perishable goods over long distances and in extreme weather conditions.
