[labnetwork] longevity of N2 purifiers

[Collins, Deon]

I would suggest investing a quality PSA and ditching the purifiers. In the end the PSA will pay for itself and will be more reliable and requires little to no service.

Subject: [labnetwork] longevity of N2 purifiers

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,
--
