The roll-up door refrigerated container is a specialized piece of cold chain storage and transport equipment built upon the foundation of a standard refrigerated container, in which the traditional swing-out doors have been replaced by an insulated, top-rolling shutter door. While retaining a fully intact thermal insulation and refrigeration system, this design effectively resolves the critical drawbacks associated with traditional doors—namely, their encroachment on operational space, the inconvenience they pose during loading and unloading, and the rapid loss of refrigeration they entail. Capable of accommodating a diverse range of scenarios—including maritime and overland transport, temporary storage, and high-frequency cargo handling—it stands as a mainstream component within modular, mobile cold chain logistics.
Two primary standard sizes are available, designed to suit the vast majority of logistics scenarios:
20-foot Standard Container: External dimensions of 6058 × 2438 × 2896 mm; ideal for use in smaller sites, short-haul transfers, and temporary storage at forward distribution centers.
40-foot High Cube Container: External dimensions of 12192 × 2438 × 2896 mm; ideal for the long-distance transport of large-volume cargo and for use in large-scale cold chain transit and warehousing hubs.
The universal temperature control range spans from -25°C to +15°C, allowing for flexible adaptation to various operational requirements—including fresh-keeping, deep freezing, and low-temperature constant-climate control—as needed. Equipped with refrigeration units from leading brands such as Carrier and Daikin, these containers deliver precise temperature regulation and ensure stable, reliable operation.
