<p class="MsoNormal">Hello Richard,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">At MNMS Cleanroom in MechSE at UIUC, we used <a href="http://www.onsitegas.com">
www.onsitegas.com</a> 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.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.

<p class="MsoNormal">Greetings to All,<o:p></o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
