[Dsg-rich] Nitrogen system

[Tyler Lemon]

Hello Morgan, 

Thank you for letting us know Hall B's N2 flow would be affected by work today. 

You mentioned that the regulators for the N2 system are being rebalanced. What is meant by rebalanaced? 

Also, for my own information, where are these regulators located? 

Best regards, 
Tyler

Greetings, 

During the morning hours of the next hall opening, presumably Monday, November 5, possibly Tuesday, November 6, the Nitrogen gas system will experience some pressure changes while the regulators are being rebalanced. The pressure changes are expected to be in the 5-10 psi range. At the end of the aforementioned rebalancing, there may be a slight increase in the pressure of the Nitrogen going to the hall. The said increase may be around 5 psi, maybe less, maybe a psi or two more. 

If you have any equipment that will be effected by the previously mentioned pressure changes during the rebalancing of the regulators or by the small increase in line pressure, please be prepared to make adjustments as needed. Hence the reason for rebalancing while the hall is accessible. 

Your cooperation, as you are, is appreciated. 

Cordially, 
Morgan Cook
