What should trigger purging procedures for a LOX converter?

Purging procedures for a Liquid Oxygen (LOX) converter are essential for maintaining the integrity and safety of the equipment. The correct trigger for initiating these purging procedures is when moisture or contamination is suspected. Moisture can lead to the formation of ice or slush, which can obstruct valves and other critical components, potentially causing operational failures. Contaminants can also create hazards, such as combustion in the presence of oxygen, leading to dangerous situations.

Regularly monitoring the condition of the LOX system is vital, but purging specifically triggered by signs of moisture or contamination is essential to ensure the system remains safe and functional. This proactive approach helps prevent more significant issues that could arise from unnoticed contamination.

Routine schedules such as monthly, quarterly, or based solely on the duration of use may not account for the immediate need based on system performance. Therefore, while regular checks are important, they do not replace the importance of reacting to specific indicators of potential issues, like moisture or contamination.
