    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>
