<p class="MsoNormal">Generally, when we repair chillers, we first drain the fluid from the system and examine the cleanliness. Depending upon what fluid you are using, it might be a good first step to refill it with clean fluid, run it for a bit, drain it
and reinspect to see if cleanliness is improving. If it’s expensive fluid, that may not be practical. Next, we would inspect the reservoir for scale and other deposits and clean it. You may need to flush it again after this depending how much debris is
generated. Once you are satisfied with the cleanliness, clean the coolant strainer (if equipped) and replace the coolant filter (if equipped). I don’t know which model you are running, but I know units like the R033 have a coolant filter that needs periodic
replacement.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If debris has built up in the hoses between the chiller and the MBE, you might consider replacing them if they are inexpensive. Generally, their length prevents effective cleaning.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">You might also consider adding an additional filter on the supply outlet if your unit is not equipped.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Just keep in mind, anything you put into the chiller has the possibility of contacting the seal on the recirculation pump. I’m not sure what material from which yours is constructed, but certainly avoid anything abrasive that might damage
it, else you will wind up with a bigger problem.<o:p></o:p></p>

<p class="MsoNormal">Dear colleagues, <br>
<br>
We have chillers from Haskris for cooling our MBE deposition system and also XRD system; I was wondering if you have a procedure that you recommend for cleaning the chillers' water. According to Haskris you can use hydrogen peroxide to clean the water should
there be any biological growth in the chiller. For this, do I need to isolate the chiller from the system or can hydrogen peroxide be run through the entire system?<br>
<br>
I appreciate your input.<br>
<br>
Best,<br>
Saba<br>
