roll the hose and copper out straight
slide the reduce on the 3/8" copper first then solder it all up
then wrap around the corny keg for a perfect circle

doing those two things makes this no harder than making a IC chiller

would using 1/2" tubing and a clamp on the end of my 3/8" CFC work? or should I step back up to 1/2" using another reducer and attach a male or female adapter ?


kinda what Captain_Bigalow did here

Wort in...


Wort out (0-100f thermometer attached)...


The second one I am making will be the conventional one featured on this thread. PM me if you are interested in it.

Used mine for the first itme this weekend and it chilled great. Only problem I have is the flow is too low to whirlpool when going through it. I was going to recirculate through it to chill in the kettle and whirlpool at the same time. I will now jsut swap a hose after it is chilled and whirlpool. Not a big deal and it sure beats putting the immersion chiller in.

As for the flow, it is the CFC and not the rest of the system. I am using a LG pump, cam-locks with street elbows and 1/2" silicon hose. I can whirlpool just fine with the CFC not in the loop. I was trying to use this beyond its design, so it is not an issue with the chiller either.

I may look into a high-flow chiller, but I am thinking that process change is better than equipment change at this point.

so I added to my CFC got a street male adapter and another 1/2x1/4 reducer I am thinking I might want a 1/4" 90 to have the hose and copper both facing the same direction.

the male adapter is not soldered to the cfc so I can add a 90 if I want.

Made my chiller after reading this thread. I really liked the connections that AHB sells, but didn't like their price so I built my own. Cost me about 60.00, but I didn't shop around for deals at all, and took about 15min to put together. Thanks for the great ideas Bobby.

I built mine one evening last week. I used 20' of 3/8 copper. Used it to brew a batch yesterday. In Wisconsin in January, our tap water is pretty cold, but the wort still came out a tad too warm. 25' might be the sweet spot.

One question - how do you get the rubber to clamp tightly to the smooth copper? I had a couple leaks I couldn't resolve by tightening the clamps. Just curious if there's a tip/trick people use to seal these up better.

Great thread - thanks to Bobby and others for contributions to make this a risk-free undertaking.

I brewed today... CFC worked flawlessly.

I used mine with my chugger pump and did a CFC back to BK for whirlpool. it took a little longer and whirlpool probably wasn't needed because the wort returning back into the BK was the same temp as the tap water 70ish.

anyways it worked perfect

@Lacrossebrewer i soldered my fittings on an used Cam lock fittings. I had no leeks at all.

I soldered a connector on the wort-in tube to use my McMaster QC, and that worked great. On the wort-out i just used a normal hose to go into the carboy. The leaks were all on the garden hose where I just had those clamped onto the 1/2" brass tubing. Maybe I'll pursue a soldered solution there, too, as I have seen a couple others do with their pics. Thanks.

This went together pretty easy and carefully coiled it around a 5 gal bucket. How much resistance should there be when i blow through the 3/8 tubing? Feels like it gained some.
