What are refrigerated containers commonly known as?

Refrigerated containers are commonly known as "reefers." This term is widely recognized in the shipping and logistics industry. Reefers are specifically designed to transport perishable goods that require temperature control to maintain their quality and safety during transit. They utilize a refrigeration unit that keeps the interior of the container at a designated temperature, which is crucial for items like fruits, vegetables, dairy products, and pharmaceuticals.

The term "reefer" is derived from the word "refrigerated" and has been formally adopted in maritime and freight terminology. It encompasses both the physical container and its purpose, making it a precise term for the context of transporting temperature-sensitive cargo.

While other terms like "freezers" and "temperature controlled units" may describe similar concepts, they are not as specific or commonly used in the shipping sector. A "dry box," on the other hand, refers to standard shipping containers without temperature control, which further distinguishes reefers from other types of containers.
