Deep-freezing area`s sectional door, has heating arrangement arranged in hollow space, and heat radiating units arranged in direct proximity to projecting edges of cover plates of front and rear sides

摘要

The door has multiple sections (1, 2) in which two adjacent sections are connected with one another around a pivoting axis in a pivotable manner. Cover plates form a front side and a rear side of the door in a closing position of the door. Projecting edges (25, 27, 33, 35) together with front surfaces of the sections define a hollow space (37), which is arranged between the sections. A heating arrangement with heating units (43, 44) is arranged in the space. Heat radiating units (41, 42) are arranged in direct proximity to the projecting edges of the cover plates of the front and rear sides.
