[labnetwork] Is Nitrogen Generator a Viable Option

[Maduzia, Joseph Walter]

Hello Richard,

At MNMS Cleanroom in MechSE at UIUC, we used www.onsitegas.com<http://www.onsitegas.com> to purchase a 99.9995% n2 Gen. They were cheaper for a better purity and flow rate than Parker. It's overkill for most of our N2 needs, but it's cheaper to supply 99.9995% to everything than to have both low and high purity N2 lines running around the facility. OnSiteGas sales team was great. We did have one issue during install. We used a SS flex hose to supply compressed air to the N2 Gen. This caused the system to "ring" every time it generated N2. I recommend using the really simple rubber hose onsitegas provides to connect from CDA to N2Gen to minimize vibration and resulting noise.

The maintenance is super simple. Just a few compressed air filters on a regular schedule. Approx $500 a year. As long as the N2Gen has compressed air, it pumps out nitrogen.

This was our sales rep. I'm not sure if he's still there.

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.
