Air Lock Doors

Vertical or Horizontal Sliding

Modern transport systems in high-bay cold storages or warehouses require very high opening and closing door speeds to prevent the entry of warm air, and oxygen as well in some cases, from outside. SALCO’s fully automatic doors (both horizontal and vertical) can operate at extremely high speeds and are suitable for frequent use and easy integration into any transport system.

Our Air Lock Doors are perfectly suited for the storage of frozen goods, sensitive goods or perishable goods. These doors come in a wide variety of design specifications to suit any application. A hermetic seal makes the doors particularly suited for rooms where the oxygen percentage needs to be reduced from 21% to approximately 16% for fire safety purposes.

Clients can choose between a 100 mm thick door leaf (chiller door) and a 140 mm thick door leaf (freezer door) for the production of their fully automatic doors.
