Frozen storage is used for products that require tightly controlled low temperatures, including ice cream and long-term seafood storage. Door selection needs to account for temperature differences, icing risk, traffic frequency and the way goods move through each opening.
Door and dock equipment considerations
- The source describes triple-layer insulated high speed doors for cold-room openings where reducing thermal bridges and frost build-up is important; anti-frost measures may be specified for the application.
- Insulated sliding doors are listed in 100–200 mm configurations for main freezer openings, with the final build selected for the design temperature.
- Personnel access can use an insulated hinged door with an internal emergency-release arrangement where required by the project.
- A dispatch bay may combine an insulated overhead door with a dock leveler and a mechanical, foam or inflatable dock seal. A telescopic leveler is described where the overhead door must close behind the dock equipment.
