Cleaning a chiller?

[Joewalla88]

Hello,
I have an idea to convert an old immersion chiller into a counter flow chiller. It's stainless steel, and I think i have an idea to make it work. What would be the best way to go about cleaning out the inside of that chiller so I'm not running beer through what might be left in there from any stagnant water or whatever would've been in there before? Ideas?

Thanks!

You could re-circulate cleaner like PBW through it for a while, or if there are no plastic bits, treat it like a plate chiller and stick it in the oven at 400 for a while, let it cool and circulate some water through it.

Haha! I don't know why I thought it would be more difficult. Duh... Thanks!

I'd recirculate hot (140°F) PBW thru the coil for 15 minutes or so. If the Solution looks discolored at all after recirculation, then drain it, and repeat the process with fresh PBW solution. When you think the insides are clean, then rinse well with clean water, and recirculate a hot citric acid solution thru to make sure the SS is well passivated.

In use, recirculate hot (almost boiling) wort thru the coil to sanitize prior to starting the chill. Rinse well after use, and insure all water is drained from the coil before storing.
