Liebig as "aftercooler"

[Danespirit]

Today i made myself a little Liebig (500 mm total).
I used relativly small diameter for the tubing, as it is only intended as a aftercooler on my "Ethylisator" project (LM).
So it's not going to cool vapours, only liquid.
Waiting for the parts to arrive, but still wanting to get on with it, i decided to take a look at my room in the basement and see what i have there.
I found some 18 mm and 13 mm coppertube, enough to make this little cooler.
As i still need to grind a halfcircle on the waterconnections it's not finished yet. You can see them at the top of the picture.
Brass connectors barbed for hose and hoseclamps.
There will be a stainless compressionfitting (1/4 ") with a copper compressionring in it for connection to the still head.
Edit: Note..you should not go with a Liebig this small diameter (internal dia.) if you want to use it for a VM even worse a potstill in stripping mode.
This condenser is intended for liquid cooling not for condensing vapour.

I've use almost same thing on my small 1.25" LM @ 700W and take off around 0.5L/h it was working ok. And on my setup it was max it can reach distillate was coming around 30 degC.

I do not yet know how much heat my Liebig will have to handle.
It will be a aftercooler for a "compact stillhead" i am currently working on. That would be a new thread (when the last parts arrive).
But like yours Kaziel, it will be a LM design, so the Liebig only has to handle liquid.
Anyway..by the length and due to the splendid heatconductivity of copper, i figured it would be alright for the job.
As i already had the tube and the fittings were on "sale", i made this little thing for only 5 $. So it wouldn't rip a hole in my pocket if i f.. it.
The tube could be salvaged and used again.
Thanks for sharing some numbers of your design...that assures me i am on track.
I will definatly not pull 700 W on this one, i expect somthing half (or lower) to be dealt with.

Nice work mate!. I did one on an old 4" LM, worked pretty good!, probably could have been bigger but I used what I had laying around like you . Good luck mate, hope it work ok!.

Thanks Googe..

That 4" Lm thingamebob , is on my bookmarks..very nice job
Did you make that needlevalve by hand?

[googe]

I wish I could make something like that by hand lol. It's just a argon gas regulator I modified, worked well!.

So it for coolin your likker? Any way to add a valve
to add to it if need be.

So I'm tole

Yes indeed Goose eye, it's only purpose is to cool the liquor, running from the stillhead.
It will be connected with a SS compressionfitting, only that i will replace the compressionring with a copper one.
Can't get the stainless to bite in that soft copper.
It looks like this one:

A valve can be easily added to the fitting (1/4").
