The ATS Vacuum Degassing Oven (VDO Touch) removes air bubbles created during in-service oxidative aging of asphalt binder by PAV. Unlike traditional vacuum ovens that measure the vacuum environment temperature, the ATS VDO Touch conventional vacuum ovens measures the stabilized temperature at the aluminum support for sample tins, for more accurate results and ease of use. The vacuum chamber in the ATS VDO Touch is necessary for removing air bubbles from asphalt specimens during testing, with precise temperature control and integration with an input vacuum system for effective degassing. The ATS VDO Touch meets AASHTO R28, ASTM D6521, and EN 14769 standards.
Features
ATS Vacuum Degassing Oven is a high-performance, automated tabletop degassing oven for fast removal of air bubbles from asphalt specimens. Built with rugged stainless steel cabinet, chamber and cover, it’s tough and easy to maintain. VDO Touch has 7in (178mm) touchscreen controller with menu-driven operation in multiple languages, for quick programming of vacuum, temperature and soak time. Comes with 4 x 236ml (8oz) sample tins and a specimen removal tool for easy loading and unloading of samples.

Applications and Benefits
The ATS Vacuum Degassing Oven is for laboratory and industrial use, especially in the asphalt and construction industry. The oven is used for degassing asphalt specimens after PAV aging, to remove air bubbles from the specimen for accurate test results. The VDO Touch benefits:
-
Fast removal of air bubbles to 15 ±1.0kPa (25.5Hg)
-
Automated tabletop degassing oven with self-contained vacuum system
-
Easy menu-driven operation with 7in (178mm) touchscreen controller
-
Removable cover has heat-resistant glass viewing window
-
Rugged stainless steel cabinet, chamber and cover for durability and easy maintenance
Includes
-
4 x 8oz sample containers
-
Specimen removal tool
-
Stylus & clip
Sample Capacity 4 x 8oz or 8 x 4oz sample containers
Temperature Range Ambient to 392°F (200°C)
Temperature Accuracy 0.2°F (±0.1°C). The oven measures the degassed asphalt temperature at the aluminum support for the sample tins, not at the vacuum temperature like conventional vacuum ovens.
