产品名称:B091M-01真空脱气炉Vacuum Degassing Oven (VDO) – Bitumen Air Removal System
产品编号:B091M-01
符合标准:EN 14769 ASTM D6521 AASHTO R28
The Vacuum Degassing Oven (VDO) is designed to efficiently remove air bubbles formed in asphalt binders during PAV (Pressure Ageing Vessel) oxidative ageing. This process ensures the binder reaches a stable and homogenous condition, ready for further rheological or physical testing such as DSR or BBR.
The VDO offers three operating modes—Fully Automatic, Semi-Automatic and Manual—to meet the needs of routine laboratory workflows as well as advanced research. Temperature is precisely monitored by a Platinum RTD sensor, while an over-temperature limit switch guarantees maximum operational safety.
A fast-acting vacuum and heating system allows the oven to rapidly reach the set conditions. At the end of the cycle, the unit features automatic pressure release, ensuring safe and user-friendly operation. The double-vessel design accommodates 4 or 8 samples, increasing throughput for high-volume laboratories.
A front USB port allows data export, storage and software updates, supporting seamless integration into digital laboratory environments.
