Abstract
An automatically adjustable swing seal for a rack-aisle freezing and chilling system extends, for example, from the top horizontal frame member of a racking structure and defines an intake opening along with side seals and a bottom seal. The swing seal is positioned at a height such that a product stack having a top edge positioned at any point along the face of the swing seat creates a seal between the intake opening and the stack via the swing seal, the side seals, and the bottom seal. Thus, stacks of varying heights may automatically be accommodated. Further, the bottom edge of the swing seal may be beveled, such that if a product stack is not evenly stacked a portion of the uneven stacking will not catch against the swing seal when the stack is pulled away from the opening.
