dad300, that's your column condenser right? (reflux)
Not your product condenser? (spirit)

Top pic is a Product Condenser from keg spear for any use strip or spirit.

Second pic is a Reflux Condenser, but could be a big ass Product Condenser. It would work.

Third pic is the 5/8" CSST in the top of a 2" column as a Reflux Condenser and hoses.

Found some csst, a choice of DN8, 10. 12. or 16. That's 7/16" 9/16, or 3/4". Post from Germany doubles the price!

My keg spear is 1/2"
(Not) working the math from Cu to SS Let me check this Dad before I order:
60" dn12 enough? (Say 2m for cc) Plus 1m dn16 for product cooler

I'll take a pic tonight of a 1/2" reflux condenser.

And what's the design for the product condenser?

CSST 2.jpg


Background is 16" tile.

1/2" X 60" CSST Reflux Condenser, and right is 5/8" x 48"...both work perfect. The SS Scrubbie is there to keep stuff and wind out of the top. I leave the tails long as I use them to move the coils. I connect water by putting pvc hose directly over the tube.

The 1/2" fits inside a 2" column and the 5/8" is for a 3" column.

That's good to see.

That will replace my copper coil in the 3" SS bokacolumn. With an SS leibig I will be copper free outside of packing.

For now my 2"copper VM/LM head gets a new SS coil but retains Copper sheath, with Harrys bypass and lyne arm

I now sense my 4th still design brewing, only been at this 8 months so each has had just one spirit run so far. I seem to be more of a still builder than a stiller!

Have there been any similar tweaks or re-generations of CCVM designs? The drawings I've seen after de Hanoi look a bit beyond my welding skills

Build CCVM all from SS triclamp is about as cheap as you can get.

I can't see how dads keg spear product condenser joins up... Looking forward to the pic as promised, Dad

Of course the coolant flow carries thru from product to reflux condensers but.... do they snake in and out the mouth of the leibig? I presume the 1/2" cooling pipes exit at the same place product trickles out ?Perhaps the alternative you alluded to of coiling around the outside of product pipe is more possible....

I found a shop today with a choice of 3" tees and bends, swept or tight. Is it best to use equal tee and keep the horizontal bit to a minimum, to turn vapor down asap?
I priced a set clamping rings locally at about 25usd each. Would a few weld joints not be a lot cheaper/neater? For example there seems to be 6 sets of clamps at the tee and condensers. Is there an advantage to clamping the RC on, or the reducer to spear?

Flex end r.jpg


I've done it several ways but this is the easiest and most straight forward.
Other end is triclamp over keg spear and the 180 deg bend is in a 2" to 1.5" reducer.

Yes but how does the product trickle out, doesn't the csst pipes come out the same end?

Bend the CSST up a little and the product flows next to them...

Is that a sock in it! I noticed tar staining in my tails, if that white fuzz is fabric to raise the pipes it will clean as well, neat.

This CSST must have good surface area bathed in distillate, I wonder if you get any smearing? there must be a fair volume of retention inside the condenser. .

I just realised seeing your bowl collector that there can be no copper parrot to monitor ABV.

The outer sleeve looks (but wouldn't be) insulated. I presume it's a plastic drainpipe for a second water jacket.
Are both required do you think? Where did you find the coil-in-spear maxed, say, for a 24" pipe

My 18" Cu leibig is 3/4" and uses so little water I need a needle valve, even when stripping. For a similar leibig in SS would I need 6ft? I read Hookline saying SS is 1/25 the conductivity of Cu but in practice how short can it be.
I have space for a long leibig. It's just SS tubes won't bend, are thick and heavy

It is a piece of gauze, not a sock.

It's only there to keep wind from entering the Keg Spear. You won't have to raise the pipes. Bending them up for the connection will hold them in place.

I put a larger bowl under my collection cups. In case I get distracted or spill some.

The outer sleeve is 1.5" PVC with end caps epoxied to the keg spear. The PVC outer jacket allows for some massive power when striping.

If you run your Product Condenser in series with the Reflux Condenser...the flow required for the Reflux Condenser becomes the driving factor.

I have run a keg spear dimroth (CSST up the middle) and the PVC outer jacket is not needed, but it is nice. Product comes off about 5 deg higher than ambient water temp.

On a 2" column, the keg spear would be sufficient. It works on my 3" column during a spirit run.
