What is the significance of 85 psig in LPA operations?

In LPA (Low Pressure Air) operations, 85 psig holds significant importance primarily because it marks a threshold point regarding the pressure management within the system. Specifically, at this pressure level, the high-pressure (HP) air system is designed to kick in and provide backup support when the pressure in the LPA system drops to around 80 psig. This automatic transition ensures that there is a consistent supply of air pressure maintained in the system, preventing any potential drops that could affect operational performance or reliability.

This functionality is vital in maintaining system efficiency and preventing failure modes that could arise from inadequate air pressure. Such backup mechanisms are critical in ensuring that operational standards are met and that the processes relying on LPA maintain their integrity and effectiveness.
