Sliding door is a common type of door in cold storage, which can be opened and closed by sliding the door horizontally along the track. It is suitable for scenarios that require high space utilization and sealing. The following provides a detailed analysis from the aspects of advantages, disadvantages, and applicable scenarios.

advantage:

Space saving: The door slides parallel to the wall, occupying no internal or external space, suitable for scenes with narrow passages or frequent transportation.
Good sealing: Adopting a track sealing design to reduce cold air leakage and excellent insulation performance.
Automation compatibility: Easy to integrate with electric drives and induction switches (such as radar sensors and rope switches), suitable for high-frequency use in logistics cold storage.
Strong durability: The track design reduces door shaking and is suitable for heavy-duty doors or large cold storage facilities (such as large logistics centers and quick freezing warehouses).

Disadvantages:

Installation complexity: requires reserved track space, with requirements for wall flatness and track load-bearing capacity.
High cost: The cost and maintenance of electric sliding doors are higher than those of ordinary hinged doors.
Dependent on electricity: Electric doors need to be manually opened in the event of a power outage and must be equipped with emergency devices.

Applicable scenarios:

Large logistics cold storage and frequent access to distribution centers.
Scenarios with narrow passages or requiring automated management, such as fresh food e-commerce warehouses.

Maintenance precautions

Regularly clean the track: avoid accumulation of dust or frost affecting sliding.
Check the sealing strip: replace it in a timely manner if it is aged or damaged to prevent air leakage.
Lubricate pulleys/bearings: Apply low-temperature grease (such as -40 ℃ applicable models) every quarter.
Power system inspection: The electric door needs to be regularly tested for power-off emergency function.
