Anybody got a counter flow like this?

As I want to whirlpool I think I know where I am going to go on this one.
Thanks for all the comments guys.

@CH - http://www.nationalhomebrewclub.ie/forum/index.php/topic,5267.75.html or page 6 of my electric brewery build, I have photos of how I put my cfc together.

An opinion and observation: I know people use the convoluted or wrap wire around for more turbulence, but looking at the water go through the clear tubing on my cfc, I very much doubt a bit of wire is going to increase significantly an already turbulent environment. I'd love to see a side by side.

But either way, my 10 metre cfc does the job on one pass to get it down to 24c - providing the wort is not being pumped full throttle. For the record though, I whirlpool back to the boil kettle. About 40/50 mins, ground water temp dependent and pump full open, to get 52lts of wort from 100 to under 24c.

Here's a question for you: 70euro in parts + time vs 200euro, do you think the perceived difference in efficiency is worth the price difference? If you do, go for it. You have to be happy with what you have or it'll cost you more in the long run, IMHO.

Do you reuse any of that water? I feel bad capturing only one bucket of hot water with my 10 minute chill time.

No I don't use any of that water. It's a bit of a waste.  I might get a water butt and keep it for the garden, but then, it sure rains a lot here anyway.

24 Degrees is way too high for me
Currently I can get using double coil immersion chiller 54l down to 18 Degrees in 22 mins whirlpooling

Or 25l in 14mjns to 18 degrees or 10 degrees takes 19 mins

If I can get the same performance from a counter flow chiller that's not blocking my perfect hop cone that will be good enough for me.

You have achieved your cooling by using 10m of tubing or 30 feet but that's a lot of dead wort in there do you just drain it or something?

The convoluted tubes are circa 12ft in length or 4 metres but are a lot more thermally efficient.

It's not about money btw it's about brewing good beer besides 70 euros + my time = €470, well you didn't ask me my hourly rate

Doesn't take everyone 20 hours to build

Hahaha. Very good.

There is only about a litre of wort in the cfc 10mm pipe. I'm not too worried about that to be honest.

Pretty good results on the immersion chiller. I would say in winter I could get the temps lower than 24c no problem. I'm only going on the dial thermometer on the output of my cfc. I'm being conservative with the 24c I would say.

But, it is definitely 40/50mins to bring 52lt of wort to under 24c in the boil kettle from 100c by whirlpooling through the cfc back to the kettle. Once I have it under 24c then, I stop the whirlpool and pump through the cfc to the fermenter, cooling it more.

I think you should be able to achieve the temp you want with a cfc, but whirlpooling back into the boil kettle through the cfc might take longer than you are now doing it.

30 mins max with one arm tied behind my back blindfolded on 1 leg in a windtunnel,...here all week try the veal

[Leann ull]

Absolutely right and so I am borrowing one before I buy.

[armedcor]

Selling that double coil immersion?

Vultures hovering

Usually my older stuff I try and give away to the local guys

This one may have to go down the scrap metal merchants tho

[armedcor]

That's some amount of copper!!

[Leann ull]

2x10m coils

2x10m coils

Why not make your own counter flow chiller from the existing chiller copper? Scrap yard won't give you didly squat for the copper.

I built my own but the stainless steel model that Imark bought from ali-express seems dear but by the time you have bought all the bits needed it was fair value.
