Hi Joseph,<br>
<br>
In my experience the pressure of the gaseous N2 entering the
building is of the order of 100 psig.<br>
<br>
You can estimate the required flow from the utility matrix prepared
by your design team. If other labs in the building need N2, please
add their estimated usage to the flow.<br>
<br>
LN2 tanks come in various volumes. The one I had at UPenn was 6,000
gallons and come with two vaporizers that alternate on their roles
of generating gaseous N2. At UDel I have two 3,000 gallons tanks,
each with two alternating vaporizers. At both UPenn and UDel, the
tank(s) feed both the cleanroom and the research labs in the
building.<br>
<br>
To avoid major issues with ice on the vaporizers, please try to
avoid having the LN2 tank(s) and vaporizer(s) on the North side of
the building. <br>
<br>
<br>
Cheers,<br>
<br>
Iulian<br>

Hi Everyone, we are in the early stages of building a cleanroom
facility and looking into nitrogen production as well. I am
interested in any options. The vendors that I have spoken with
require N2 purity, flow, volume, and pressure. Any advice on
how one would roughly calculate the latter three parameters, or
have values based on usage by your facility? I have been using
the latter option and scaling our requirements accordingly based
on tools we plan on acquiring, and roughly what our facility
usage would be. </div>
