A sterilizing tunnel (10; 10a) for pharmaceutical containers (1) has an entry zone (11), a heating zone (12), and two cooling zones (13, 14). The individual zones contain ventilating fan units (22, 23, 24) that generate air currents, which serve to heat and cool the containers (1) that a transport apparatus (17) conveys through the sterilizing tunnel (10; 10a). The invention proposes that the heating and cooling units, which operate using the principle of heated and cooled air flows, be supplemented with radiant heat-generating heating units (35, 36, 37, 40). The sterilizing tunnel (10; 10a) according to the invention makes it possible to achieve a uniform heating and cooling of the containers (1), preventing stress cracks in the containers (1) and permitting intentional heating that makes it possible, for example, for the containers (1) to be coated with a substance.
