Exterior dimensions are approximate and include the integrated skid and closed-loop cooling system.
Heating and cooling rates are average air-temperature rates at maximum pressure with the rated thermal load.
The vessel is rated 15 psi above the normal maximum working pressure so the relief valve is not triggered in normal operation.
Boeing autoclave certification D6-49327 requires at least 9 part thermocouples.
Vacuum and thermocouple quantities can be changed, and any of the world's power requirements can be accommodated.
