[labnetwork] Heated gas lines

[Tom Britton]

Hello Matthieu,



I missed seeing you at Harvard a couple weeks back. I'm sure you would have enjoyed it. I hope all is well.



Here is what we would recommend:



Typically with gases that need to be heated to prevent condensation, the best practice is to keep it the distance short as possible from the source to the point of use. With that being said, if distance is the issue, the two key elements are temp and pressure, a gradual increase in temp from the source to the point of use and a decrease in pressure will be your best bet to minimize the chance of condensation.



Please let me know if you have any questions.

Tom

Dear colleagues,



We are undergoing an analysis of our gas network and I would like to get the best practices out there.



For gases that need to be heated in order to avoid condensation, is it best to have the cabinet as close as possible to the tool ? Or, if one wants to consolidates all gases in the same area, could we have them far away ? if yes, how do you address the condensation issue.



Thanks
