Abstract

The present disclosure provides a swing door system for use with a freezer device, including two adjacent swing doors and at least one mullion in contact with the swing doors. Each swing door includes a transparent pane and a non-transparent area, with each non-transparent area proximal to the mullion when the swing doors are in a closed position. The non-transparent areas and the mullion define a non-transparent region. In a plurality of horizontal see-through angles, a view through the transparent panes is not totally blocked by the non-transparent region. The horizontal see-through angle is measured with respect to the plane in which the swing doors are arranged when the swing doors are in the closed position. When a width of at least one of the swing doors is in the range of 500 mm to 780 mm, the plurality of horizontal see-through angles ranges from 6° to 174°, preferably 5° to 175°, and more preferably 4° to 176°. When a width of at least one of the swing doors is in the range of greater than 780 mm and equal to or lower than 1000 mm, the plurality of horizontal see-through angles ranges from 5° to 175°, preferably 4° to 176°, and more preferably 3° to 177°.
