[labnetwork] longevity of N2 purifiers

[Kyle Keenan]

Hello All,

Our cleanroom has been in operation for 11 years and, for high purity N2,
we use local purifiers. Given their age, I'm starting to wonder if/when
they might need to be replaced. I've looked into it, and doing so would be
quite costly. I know there are a ton of variables at play, but generally
speaking, for an 11,000 sq/ft facility that uses UPN2 on, perhaps, 15-20
pieces of research equipment and for N2 guns at ~15 wet benches, what would
be your expectation? Is this something we even need to worry about?

I'd be interested to read your thoughts.

Best,
