Reefer Container

A reefer container is a specialized shipping container equipped with a refrigeration unit, used for transporting goods that require low-temperature preservation, such as fresh produce, frozen foods, and pharmaceuticals. Its temperature can be precisely adjusted, typically ranging from -30°C to +30°C, with some models capable of reaching as low as -60°C. Usage scenarios include sea freight, land transport, and multimodal transport. Precautions: Confirm the required temperature, humidity, and ventilation requirements for the cargo in advance; when booking, specify 'reefer' and apply for a power outlet; pre-cool the container before loading to avoid temperature fluctuations; note that reefer containers cost more than standard containers and require payment of a refrigeration fee. The difference from a dry container is its temperature control function; the difference from an insulated container is that a reefer container has its own refrigeration unit, while an insulated container relies only on insulating materials to maintain temperature without active cooling. Additionally, reefer containers are divided into integral (self-contained compressor) and porthole (requires external power) types, with integral types being common in foreign trade.
