Hi Sammye,While I might hazard a guess based on other facilities that
 use liquid nitrogen, I'm not familiar with that equipment.=C2=A0 My first
=C2=A0inclination would be to go to the manufacturer for more details.=C2
=A0 Aside from that, I'd consider ensuring=C2=A0adequate ventillation, poss
ibly an oxygen monitor as well, depending on whether the installation could
 become an enclosed space in the event of an unplanned release/failure.
If you haven't already considered it, a bulk/mini-bulk Nitrogen installa
tion from a compressed gas company would be the benchmark against which to 
compare costs.=C2=A0 My company (and our competitors) will=C2=A0sometimes r
etain ownership, defray costs,=C2=A0or subsidize=C2=A0a=C2=A0Bulk installat
ion=C2=A0based on other factors pertinent to the account. Its at least wort
h the comparison.Todd PerkinsSafety DirectorAirgas Mid America

rsDoes anyone have any experience with the elan2=E2=84=A2 Liquid Nitr
ogen Generator. Specifically, what should be taken into consideration with 
regards to the facility where it is housed, maintenance (including costs), 
permits, and safety in general.Any help would be much appreciated.
