The VDO Vacuum Degassing Oven adopts advanced technology and functions by generating negative pressure through a vacuum generator. It is primarily used to remove air bubbles from asphalt binders after Pressure Aging Vessel (PAV) aging and from other material samples.
The system provides real-time monitoring of temperature and pressure and automatically stores test data. The application of advanced vacuum generation technology ensures safer, more stable, efficient, and economical operation.
