First claim
Opening claim text (preview).
What is claimed is: 1. A blow molding machine with a stationary part, a rotating part, and blow molds, comprising a tempering device adapted and provided for only tempering said blow molds by use of a medium, wherein said tempering device is disposed within said blow molding machine, and wherein said tempering device includes a heating element, a cooling element, a pump, a control unit, a cooling water supply, and connections to at least one of the blow molds of said blow molding machine, wherein the control unit, the heating element, the cooling element, the pump, a cooling water supply, and connections of said tempering device are provided in the stationary part of said blow molding machine. 2. The blow molding machine according to claim 1 , wherein said control unit is integrated into a machine control unit. 3. The blow molding machine according to claim 1 , wherein said control unit is adapted to control the temperature of said medium used in said tempering device, such that formation of condensate can be reduced. 4. The blow molding machine according to claim 1 , wherein said control unit can control at least one process circuit. 5. The blow molding machine according to claim 1 , wherein a secondary heating element is provided in said tempering device and adapted to raise the temperature of said employed medium to a temperature at which formation of condensate can be reduced.
