<p class="MsoNormal"><span style="font-size:11.0pt">Hello fellow 3dem-ers,</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">We are experiencing quite an annoying situation with Airgas and I am wondering if other folks have had similar problems and what potential solutions are.</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">We have a custom manifold from Chart to deliver liquid nitrogen to our Talos Arctica that can be equipped with two 240L tanks, each with 22 psi pressure. This should help reduce the LN2 waste and be more efficient,
and when our tanks are good, it really is amazing. BUT, some of the time Airgas gives us tanks that we cannot use as the pressure never builds beyond 10 psi and we have to return full tanks. They are not the nicest about this either
</span><span style="font-size:11.0pt;font-family:"Apple Color Emoji"">☹</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">We know the manifold is working correctly, and that it is caused by individual bad tanks. Has anyone else had crappy tanks? Do people just buy their own tanks and have them refilled instead of swapped?</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Unfortunately, in Michigan Airgas is our only option, so any help would be appreciated.
