Vacuum Degassing Oven
Current ASTM and AASHTO specifications require vacuum degassing of asphalt specimens after aging in Pressure Aging Vessels (PAV’s). The Vacuum Degassing Oven CRT-VDO table top vacuum degassing oven is completely automated and includes self-contained vacuum system. The chamber accommodates four specimens in the included containers. The cabinet, chamber and cover are constructed of easily maintained stainless steel. The cover has a heat-resistant glass viewing window for observation during the vacuum degassing process.
The CRT-VDO, Vacuum Degassing Oven uses an electrically powered vacuum system to rapidly evacuate the chamber to the required 15kPa (25.5Hg). The precision controller features a digital display to indicate time, temperature, and current process stage. Audible and visual alarms alert the user at end of each process. Illuminated pre-heat, degas and end/stop buttons allow easy operation. The Vacuum degassing oven includes four 236ml (8oz) sample tins, and a specimen removal tool for easy loading and unloading of samples.
