Automated Bake Out Oven

For Industrial and Specialty Gas Applications

The Automated Bake Out Oven provides an efficient means to prepping cylinders for industrial, medical and specialty gas mixtures and/or pure gas grades of 99.999% purity levels or better by removing moisture and any trace contaminants from cylinders being put into service. The system uses a cycle of heat, vacuum and purge gas to remove the contaminants.


A custom PLC monitors the vacuum pressure, cylinder wall temperature, oven temperature, and purge pressure. The unit also provides multiple safety parameters and alarms for situations such as if the vacuum is taking too long, overheating, no purge gas is available, etc. If a vacuum pump is also ordered, a custom vacuum pump motor starter and thermal over load are included to simplify connecting the vacuum pump of your choice.

Features and Benefits

  • Can have purge pressures up to 200 PSI, drastically improving the efficiency and reducing the time required in the cylinder preparation process

  • Convenient double door design provides quick and easy access for loading and unloading cylinders with no ramps to roll cylinders up or down on

  • Designed with a 1" stainless steel pipe header, all welded, eliminating the potential for leak points
