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equipment built upon the foundation of a standard refrigerated container, in which the traditional swing-out doors have been replaced by an insulated, top-rolling shutter door.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.
External dimensions of 6058 × 2438 × 2896 mm. Ideal for use in smaller sites, short-haul transfers, and temporary storage at forward distribution centers.
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.
| External Dimension (MM) | 12192 × 2438 × 2896 |
| Internal Dimension (MM) | 11590 × 2294 × 2554 |
| Door Opening (Height) | 2360 mm |
| Refrigerant | R404A / R452A |
| Internal Temperature Range | -40°C to 30°C (-40°F to 86°F) |
Standard marine-grade refrigerated containers with double-swing doors require clearance on both sides to accommodate door swing, imposing strict requirements on aisle and loading dock widths. By contrast, the top-coiling design of our roller shutter doors creates over 1.2 meters of additional operational space compared to standard units—making them perfectly suited for confined environments such as narrow aisles, wall-side loading zones, and compact facility sites.
Featuring a pillar-free, full-width door opening design, this system completely eliminates obstructions caused by door posts and the need for precise forklift maneuvering. This enables the rapid ingress and egress of full pallets, boosting the efficiency of high-volume loading and unloading operations by over 30%.
The unit boasts excellent overall airtightness with minimal gaps in the door seams. Combined with its rapid opening and closing capabilities, it effectively minimizes the loss of internal cold air, resulting in substantial long-term energy savings.
The door structure is highly resistant to wind and vibration, and is designed to resist deformation, making it perfectly suitable for use in exposed outdoor environments. Furthermore, it is equipped with anti-pry locking mechanisms to ensure high-level security. Additionally, we offer customized modification services for refrigerated containers, allowing us to tailor the unit to your specific operational needs—serving a dual purpose for both transportation and stationary storage applications.
The fundamental difference lies in the door structure: the roll-up door retracts upward into the top of the cabinet, thereby requiring no clearance space on either side for operation; in contrast, the hinged doors of a standard refrigerated cabinet open outward, necessitating a substantial amount of space to be left clear for opening. Aside from this distinction, the insulation of the cabinet body, the refrigeration system, and the external dimensions are identical for both models.
There are two types: manual crank and electric. The choice depends on the specific usage scenario.
Two primary standard sizes are available: a 20-foot Standard Container (external dimensions 6058 × 2438 × 2896 mm) ideal for compact sites and short transfers, and a 40-foot High Cube Container (external dimensions 12192 × 2438 × 2896 mm) designed for long-distance transport and major cold chain transit hubs.
The universal temperature control range spans from -25°C to +15°C (with internal temperature capability between -40°C to 30°C / -40°F to 86°F), utilizing Carrier or Daikin refrigeration units with R404A or R452A refrigerants for deep freezing, fresh-keeping, and constant-climate storage.
By rolling into the ceiling rather than swinging outward, it frees over 1.2 meters of dock area. The full-width, pillar-free opening removes door-post barriers, enabling rapid pallet forklift loading and unloading that boosts operational efficiency by more than 30%.
Yes. Customized modification services are available to tailor the unit to exact on-site requirements, serving a dual purpose for both intermodal logistics transit and stationary outdoor cold storage with anti-pry locking security.
