<p class="MsoNormal">The RF folks have small SMC chillers to cool MO/LO systems in linac service buildings. I do not know if they have a spare nor if the capacity meets your requirement. I doubt the capacity suffices, but you might as well try. Nor do I
know delivery times, they might. <a href="https://www.smcusa.com/products/chillers">

Jay and Doug,<br>
The chiller used for NPS has developed a leak. They are trying to fix it, but the first attempt<br>
yesterday failed. It is a Model 030. It circulates water at ~20C+\- 0.1 c. WOuld you have an idea<br>
if someone around the lab has something similar that we could use if it cannot be fixed that<br>
we could ask?<br>
<br>
Cheers,<br>
Mark<o:p></o:p></p>
