Vacuum Degassing Oven

Vacuum Degassing Oven (VDO)— H-1641

The Vacuum Degassing Oven (VDO) is used to precisely and accurately degas pressure-aged binder samples to meet AASHTO R28-06 and ASTM D6521-05 standards. The compact, table-top unit is constructed of stainless steel with a hinged lid to conserve space while allowing easy access to the stainless steel vacuum chamber. The oven holds up to (4) specimen containers and features a self-contained, automatic vacuum system. The high-precision controller features a digital display indicating time, temperature and the current stage of each process, as well as illuminated pre-heat, degas and end/stop buttons. It also features audible and visual alarms, indicating end of process. Over temperature protection is provided by a pressure safety release solenoid valve. The VDO includes (4) specimen containers and a specimen removal tool.

Vacuum Degassing Oven— H-1632

The Vacuum Degassing Oven (VDO) is used to degas pressure-aged binder samples to meet AASHTO R28-06 and ASTM D6521-05 standards. The H-1632 vacuum degassing oven (VDO) is a compact, tabletop design that provides push-button automation of the degassing process. The simple control panel has only three buttons to control the process: Preheat, Start Process and Stop; and, an end-of-cycle alarm lets you know when testing is complete.

The VDO is made from durable stainless steel and features a fully-integrated, vacuum source, which is air-powered. It uses a venturi driven by a laboratory compressed air supply capable of providing compressed air at 6.5 bar pressure or more. A flow rate of approximately 55 liters/minute is required for 30 minutes. The air must be filtered and dried – the venturi produces a chilling effect, and moisture can freeze, expand, and damage the venturi unit. The H-1632A is almost totally silent when producing vacuum and has no moving parts to wear out or break, other than an air flow control solenoid valve.

The H-1632A Vacuum Degassing Oven is furnished with: (4) 250 ml (8oz) sample tins, (2) O-ring gaskets, AC power cord – IEC 340 Type, Stainless steel lid with 5-1/2” diameter heat-resistant glass viewing port and metering valve for vacuum adjustment, Quick-disconnect coupling for user’s air supply and an air line filter-dryer for installation in supply line.
