Abstract

Heat treatment unit comprising a device for measuring the initial temperature of preforms. The heat treatment unit (4) comprises: - a chamber (16) extending between an inlet (18) and an outlet (20), - a heating device arranged for heating preforms, - an upstream measuring device for an initial temperature (Ti) of the preforms (2) at the inlet (18) of the chamber (16), - at least one control module (24) arranged for adjusting the heating power (Pc) of said heating device (10). The control module (24) is configured to adjust the heating power (Pc) during a variation of the measured initial temperature (Tim) as a function of the predetermined heating temperature (Tc), the measured initial temperature (Tim), the rate (C) of preform flow in the chamber, and at least one constant coefficient (K) for a desired container (1) to be produced.
