Patent ID: 8579622

Claim:
A blowing machine for manufacturing containers of correctly temperatured preforms, comprising blowing stations having correctly temperatured blow molds correctly temperatured through a liquid-driven primary function temperature control system, functional get-up components assigned to at least the blowing stations to at least one of control or monitor secondary functions during production, and, in order to bring at least some functional get-up component for secondary functions to the correct temperature, an electrically operated controllable liquid temperature control system supplied by at least one temperature control device integrated into the blowing machine and guided through the functional get-up components, the at least one temperature control device is located outside the blowing machine or inside the stationary part or inside the rotating part and is connected with the temperature control circuits via a forward run and a backward run, and wherein, in at least in one major temperature control circuit connected to the forward and the backward runs, at least one circulation pump, upstream of the circulation pump between the forward run and the backward run, one bypass connection is provided, and in one of the forward run or the backward run at least one electrically operable mixing valve is provided.
