Man oh man, I have got to search the forum more efficiently. This would have saved me a few bucks. Great job Bobby M!

I must live on top of a glacier. I used gravity and by the time the wort flows through the cfc and into the fermetner it's easily down to 65. i could go lower easily but this is with my ball valve all the way open.

One thing to mention about gravity. If you do not have the level and orientation on your hoses right it will not flow! PIMA saturday. Thought it was stuck, but once I got it repositioned she started flowing. I made sure to take a picture so i could duplicate it next brew day. (No Stand)

O.K., I've read this thread and I have a pretty good grip on how to construct it. So far, I've built my system out of stainless in order to make cleaning in place easier. Now, I'm wondering if there is any reason to build my cfc with stainless instead of copper. The only reason I could see for doing so is if I hard pipe it in place. Right now, that doesn't seem like something I'm going to do, but who knows. I guess I could always build it and sell it later. Up until now, I've always used a copper IC. I was going to continue to use it since it was easily removed for cleaning. However, I'm starting full time 10 gal. AG and know that the cooling time with an IC will be greatly increased. What do ya'll think - Dwain

I think you will not regret making a CFC. And no reason to go SS over copper unless you have money falling out of your pockets.

I am going to build one of these CFC

is AC/Refrigerant line ok to use or do i need to use TYPE K or L ?

I would assume since the cfc will not be under pressure the the AC line would be ok, but dont want to overlook something.

thanks

The thermal conductivity of copper is much better than for stainless steel. There's no downside to using a copper chiller AFAIK.

I am considering switching over to an IC. Here's my reasoning: I was listening to a podcast this week and Jamil mentioned that using a CFC will get the wort down to pitching temp faster, but not all of it at once. You will have whatever is in the kettle still at a high temp until it reaches the CFC. An IC will bring the entirety of the boil down at the same time.

And the kicker is that it doesn't have to reach pitching temp to do the job. It only needs to go down to a certain temp, like 140 F or something, to do the most benefit. So if HSA is not a real concern, as it seems, then gently swirling the wort around an IC is not a bad thing.

So an IC takes a few more minutes to bring to pitching temp, but might actually be better for the wort than a CFC just because it bring the whole volume of wort down to safe temp faster??

This is why many people recirculate back into the boil kettle until the temperature of the whole batch is under 140F. I've done it both ways, and never noticed a difference. I suppose for lagers, or gently hopped beers you might notice a difference because the hops are in there for longer.

There is some truth to the benefit of getting the whole wort under 140f quickly, but I literally run 12 gallons out of the kettle in 5-7 minutes. We're getting a little nit picky with a couple minutes here. Now, for those who gravity drain through CFC's or plates, that could be a downfall.

That's the way I do it and I have noticed a difference in the flavor and aroma hop intensity. Provided you can push a sufficient volume of wort through your CFC, the difference between using an IC or CFC is probably quite small. The problem is that many of the CFC's use small diameter soft copper tubing which severely limits the recirculation rate and that puts them at a severe disadvantage, particularly with larger batch sizes. Using gravity alone with one of the small tubing CFC's takes way too long IMO. Using a pump is certainly an improvement, but still not fast enough for me.
