The Witzel PO1200 convection oven has been developed for the special needs of Pre-Preg processing in the O&P field. The large housing with double doors allows to place multiple hanging molds inside the oven. A standard 4x vacuum connector is mounted inside the oven. An external water separator is placed at the right side of the housing.

 

During development special attention has been focused on the control that manages the heating process. The “Heart“ of the system is the microprocessor based central control unit with its proprietary Witzel software and user interface.

The integrated touch-panel and its interactive menu control allows an intuitive operation of the multiple functions. The entire process it can be monitored and directly controlled through the use of an external temperature sensor (included). Simply place the thin-wire sensor at the edge of the Pre-Preg material, between the layers and plugged into the front panel of the control unit. Thus the entire heating process is controlled by the exact core temperature of the material.

Further an integrated Timer- and Ramp-feature allows to program and store individual heating graphs. This provides the user a visual representation of the entire heating process with an easy-to-understand graph. Variances may be monitored by a screen entered from the main menu.
