[labnetwork] No water flow? - AccuThermo AW610M RTP

[Richelson, Tucson]

Hello Leslie,

I blew some N2 through the lines and some milky water came out. It seems to be pumping fine now. If it fails again I’ll try that.

I’ve read and re-read the manual. This is still all new to me and I might still be wrong but here’s what I’ve learned so far.
There are three cooling systems. One is water (from the house) to cool the oven. One is N2 to cool the quartz isolation tube. And lastly is water (from a chiller bath) to cool the pyrometer.

I did reach out to Allwin and they got back to me, so thank you for your good suggestion, and thank you for responding!

Hi Tucson,

The cooling lines on these tools are know to gunk up over time. I suspect you’ll need to undo the fittings to check for blockages. ALLWIN has a solid support team that can guide you through the process.

Also, I thought the chiller was meant to cool just the door assembly and not the internal components. Forgive me if I’m wrong but it could be that the house cooling loop is what feeds the pyrometer.

Good luck!

Hello everyone,

We have a AW610 RTP and we noticed that the pyrometer coolant water wasn’t flowing. We disconnected the chiller bath and tested it separately and confirmed that it was pumping water. Has anyone else experience this? Any suggestions on how to fix this?
