SS Convoluted Counterflow Wort Chiller?

[LBussy]

One question LBussy did not answer either, what's the size of a batch you can cool down with a 20' or 25' CFC?

Not sure if I was clear so I'll re-phrase that part of my answer. You can run any size batch you want through it, the size only matters in that it takes longer to run a larger batch through. I only ever ran my wort through in one pass so there's no pumping/recirculation. The 25' length pretty much guaranteed that the wort coming out was within a couple of degrees of the water going in.

Right - the answer is "an infinite size batch", as long as time is not a consideration

Cheers!

Thank you, my mistake, I skimmed your first reply too fast, and did not get it correctly. I don't know whether I said so, but my mother tongue is French.
But now I do understand what you mean, in fact my question does not make sense oops. I'll go for 25'
Aeration is also a good idea. In my other activity, I use an aquarium pump and an air stone, here I'll try your drilled racking cane method, it looks like a kind of Venturi effect...

That is it exactly. I've never tested the dissolved oxygen using that method - all I know is it worked before I knew I "had to" use oxygen and a stone.

Your English is perfect. Every time I converse with a person in English who speaks a different native language, it reminds and saddens me that our kids are not forced to master a second language.
