[labnetwork] Is Nitrogen Generator a Viable Option

[Collins, Deon]

We have N2 supply via a generator. We supply both High purity and Ultra High purity N2 to our labs. The installation of an N2 generator will greatly reduce you LN2 cost but will have a large upfront cost as we have 2 N2 delivery(hard piping) structures in place. I would have to go through some historical data that is decades old to get you numbers but a it all depends on use. Best guess is a couple years out on ROI but it is a no brainer if you are a heavy N2 user.

Greetings to All,
I am writing because we are being challenged, like everyone, to reduce our cost for research. We are considering other options for our Nitrogen gas source including a Nitrogen generator due to the recent cost increase of LN2. We are currently using a 2-tank system which supplies both the liquid and gaseous nitrogen to our facility.
We are averaging 80 to 90 SCFM of utility nitrogen and 6 -7 SCFM of High Purity Nitrogen. We would continue to maintain our liquid nitrogen supply.

Please provide your positive and negative experiences with Nitrogen generators as well as the manufacturer of the unit. All comments/suggestions are welcomed.  Thanks in advance for your input.
