<p class="MsoNormal">HMNTL recently installed a large PSA for N2 use in our facility. HMNTL uses both liquid and gas Nitrogen within our facility. We are seeing a 4050% savings in liquid nitrogen deliveries. If you do not need a constant nitrogen purge you
could see greater savings. We constantly see 6.6 for purity at 116psi.A psa will require an oilless compressor. I suggest going with a variable speed drive compressor not a compressor with a slide valve. The slide valve doesn’t offer the energy savings or
longevity of a vsd. I oversized our PSA and still the ROI on our system is 2 years. Feel free to reach out with questions.

<p class="MsoNormal"><span lang="EN-GB">Hello cleanroom experts,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">We at London Centre for Nanotechnology rely on the liquid nitrogen boil off for our cleanroom tools for purging, venting, N2 gun, etc. However the running cost reviewed recently is very high. So what we propose is to
introduce a nitrogen generator to supply a large amount for daily operation, and reduce the Liquid Nitrogen consumption. Therefore the total cost should go down in the long term operation.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">It is very much appreciated if you can share your experience for nitrogen generator use at your facility.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">We are particularly interested in the following:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">What purity / grade of nitrogen can your nitrogen generator produce? Where do you use for this nitrogen in your facility: venting process chambers, vacuum pump purging, nitrogen gun? Which manufacturer do you use / recommend
to use? It is expensive to do the maintenance/service? How long do you need to have a maintenance service for the nitrogen generator?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"> <o:p></o:p></span></p>
