Maximizing the duration of guidance means in tire vulcanization systems without disturbing thermal stability

A tire vulcanization system for regulating a temperature of a heating medium, the system comprising:

• a bladder disposed within a tire to be vulcanized and defining a cavity, wherein the heating medium circulates, with a fan and a heater being immersed in the heating medium and the heater has one or more heating elements which supply energy to the heating medium before the heating medium exits the bladder along an output path, and with a shaft being concentric with an axis X-X′ of the cavity, and with a controllable motor driving the shaft;
• and
• one or more bearings positioned in a central portion of the system and below the fan and the heater so that, as the heating medium is introduced into the cavity, the fan agitates the heating medium radially outwardly in the direction of the bladder and directs the heating medium toward exits that are positioned obliquely relative to a support that carries the fan.
