Furnace for conditioning preforms

Abstract

A rotary furnace for conditioning preforms includes a heating wheel and a plurality of heating modules, each for heating a preform, that are disposed on the heating wheel. Each heating module includes a heating chamber, a holding device for holding the preform and a lifting device. The heating device includes at least one heating radiator adapted for irradiating an outer wall section of the preform with infrared radiation, a recess for introducing the preform, and walls having an insulating layer configured to thermally insulate the heating chamber. The lifting device is configured to raise and lower at least one of the holding device and the heating chamber so as to move the preform into or out of the heating chamber.
