<div>That’s good news!</div>
<div><br>
</div>
Another possible issue with getting a different model chiller (aside from needing to change the communication section of the LabVIEW code) would be if this is considered a pressure system and so would need DA approval to swap to something different.
<div><br>
</div>
<div>It could very well be an exempt system due to the total stored energy, but that’s not something I’m sure on.</div>
<div><br>
</div>
<div>This is why swapping like-for-like is always the best way to go when possible.<br>

<div style="margin: 0in; font-size: 10pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt; font-family: Calibri, sans-serif;">Thank you all for thinking about our NPS chiller problem. The Hall C techs fixed the leak this morning. It did not leak
for the 1/2 hour we observed the pipe. Hopefully, the fix will hold.<span class="Apple-converted-space"> </span><o:p></o:p></span></div>

<div style="margin: 0in; font-size: 10pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt; font-family: Calibri, sans-serif;">But just in case it doesn’t. We have one more month to go. So locating a possible spare would be a great piece of mind.

Our NPS chiller has 4,3 gallons per minute. One would need something close (or higher).</span><span style="font-size: 11pt; font-family: Calibri, sans-serif;"><o:p></o:p></span></div>

<div style="margin: 0in; font-size: 10pt; font-family: Aptos, sans-serif;"><span style="font-size: 12pt;">The NPS experiment in Hall C has a chiller that has developed a leak, do you know if any of the chillers previously used for the SVT are available for
them to temporarily use?<o:p></o:p></span></div>

<div style="margin: 0in; font-size: 10pt; font-family: Aptos, sans-serif;"><span style="font-size: 12pt;">It has a 3 kW capacity (not sure how much of this is actually needed), only needs to maintain 20C so not a particularly low temperature requirement, and
0.1C stability (also not sure how stringent this is), which is why I thought maybe one of the older model SVT chillers could be used?<o:p></o:p></span></div>
