Just a little update, currently Di water is used in the system and as we know the minute Di water touches all that stainless steel it grabs the elements it needs to return to normal ionized water. Our Di system is multi staged filtered as well. More and more the "Element Watt Density" is...

To All, we are currently evaluating the whole assembly and testing the ideas presented here. I will report back on what we find out as soon as I can. Thanks again to everyone for the help! Mark

Very true! The fillport for this circulator is behind a wall (fab clean-room chase way) and the fillport for the chem tank is in the cleanroom itself. The chase way is only occupied by maintenance members. Since this anode/heater is continual problem and not an accidental cross contamination...

The stainless steel tank/reservoir has a fillport on top and is filled with water manually. Corrugated teflon PFA tubing is used to flow the heated/cooled water thru the interior of the chemical tank and return it to the reservoir. Same principal as a cars heater core except the teflon tubing...

In the end, this just might be the path taken. But so far, everyone is helping a bunch with great ideas and confirmations to some of our thoughts as well.

Great information and a confirmation on a thought we had earlier. I will on a purge immediately. The voltage leak I will have to get some help with. Thanks

I wondered about a bushing, we are currently using teflon tape though. The heater is McMaster Carr # 3656K153, TEMPCO # TSP02245. Thanks!

By closed loop I mean that the water flowing through the heating/cooling hoses is self contained and must be refreshed manually. Just like a cars radiator. Also these exit the circulator and travel thru a larger external tank containing plating chemicals.

Yes the anode is passive and yes the heater is sheathed stainless. And we are using regular old tap water in the system. Mark

Within 3 months the anode (McMaster-Carr #3642K17) is completely dissolved. Thank you for the link!

Hi everyone! I am seeking advise to a corrosion problem, I have a circulator design I am working on. This is a 40 to 115 degree closed loop “city water” circulator. The water reservoir is 304 stainless and has a115v-1500w immersion heater, threaded into the tank. There is an overtempt snap disc...
