Shelterpupsbrew: you have a couple of neat ideas worked in there. I may have to copy the water valve.

Does the wort bypass make a big difference?

The bypass works pretty good. The CFC knocks the temperature of the wort down amazingly fast, and sort of starts the whirlpool. Once I open the bypass, the whirlpool really gets going. I would estimate that the flow rate doubles once the bypass is opened. The fittings that I used are a little on the small side, someday I might reworks the chiller to put in a larger bypass.

The water valve works well. I recently integrated the chiller into a brew stand and moved the valve to a remote location that is easier to access.

I made one tonight. I have a ball valve for the water in ready to go once I mount it to my rig and know my orientation of the coil. I made mine using the full 50ft of copper and hose. Probably overkill but why not if the material is there.
Hopefully I get a chance to run it this weekend.
Thanks for the info bobby. Saved me some time putting the parts together.

Bigger is not better in this case. I ended up cutting the 50 ft version down to 25 ft. The flow was just too slow. The 25 ft version cools from 197 input to 62 deg output.
A little better than my 30 plate chiller.

Ok after scanning through most of this thread i have one question. when using a CFC with a pump why are people complaining about being able to cool the entire batch while whirl pooling? is it the flow rate does not allow for an adequate whirlpool? or is it the recirculation through the CFC back into the boil kettle impedes the cooling process?

who out there uses a CFC and whirlpools with a pump? can i get an honest opinion of how this works in this set up? i can always whirlpool after i chill if flow rate is the issue.

hmmm i made a ~60' version of this. I haven't tried it yet. You found that reducing the length speed up the flow? I guess I didn't expect that because it was still being reduced to 3/8.

BTW if people are thinking of building this i would recommend lubricating the copper with k-y lube. I tried the water and soap thing but it didn't work out so hot.

I found that the flow was down to a trickle. This was just testing with water. Even at 25 ft it seems to be about a third of the normal flow rate. Which is fine because I am cooling. Still only takes about 5 to 10 minutes to cool 5 gallons down to 70 deg recirculating.
It is 3/8 OD. I am not sure what the actual inner ID is. I am sure the flow would be better if you had 3/8 ID.
If I make another I think I would try 1/2 copper and a 3/4 hose. Maybe someone can chime in on their flow rates at this size.

I used the soapy water and it was very easy. I have a 60 ft shop so I was able roll everything out straight and flat. Slid right in with no binding.

I cool using the CFC and a pump while recirculating back to the boil kettle. I abide by the rule that it is better to get the entire volume down in temp quickly, and this CFC does it in minutes. Then I whirlpool for a few minutes and then transfer to the fermenter. The CFC reduces the flow rate too much to get a good whirlpool, so I installed a bypass that gets opened up once the wort is cooled.

The picture does not show the pinch clamp that is used to close the bypass, but you can get the idea. You could just disconnect the CFC and run the pump out hose back to the boil kettle for the whirlpool, I just didn't want to have to move any hoses around. Hope this helps.

My process is that immediately after the boil I stir hard for about 30 seconds to whirlpool, let it settle for about 8 minutes and then let it drain through my CFC into the fermentation bucket or carboy.....no pump used. Drains out in about 25 minutes max. Is it quicker to recirculate wort with pump to cool it down and then drain or pump into carboy? I just figured with my process it was simple and I was using one less piece of equipment (pump) to touch my cooled wort.
