shotgun condensor mini

[dougyethanol]

Ive made a shotgun style condenser at 19mm/3/4" outer tube.
Here are the parts.

2 tees,2 sleeves, 2 reducers,i length 3/4 pipe, 3 lengths 1/4 pipe(twisted) and 2 caps with 3 holes drilled.

Believe that's a Graham condenser

Nice one. Really a new type of condenser, a shotgun/graham/liebig hybrid.

Maybe we should call it a a Dougy condenser

Pretty sure .mash rookie.or old dog built some.like that in glass

Might be pushing it there . A Graham is usually a fairly tightly coiled product path in a coolant shell .
Not sure if a twist or two quite makes the grade ..... but I guess it is a coil , elbiet very stretched out

Dougy , I think the twisted pipes are a good idea as it will assist turbulance in the coolant jacket .I did a similar twist on my shotty .

But I have to say ,the internal area of 1/4” is pretty small and without doing the math , I wonder if a single 1/2” tube would have more available cooling area .

Another thing that comes to mind is potential for blockage . If you use this on a boka or the likes , no worry’s , but Never use it on a pot still with a mash in it .
We recommend 1/2” as a bare minimum for safety reasons against potential blockages.

Nice shotty! I totally agree and think the same is true on the inside with vapor.

I did a quick calculate, 12mm vs 3 x 6 = 18 - 50% more cooling. My main still runs a 1/2 inch with 3/4 jacket, 1metre long, fine for stripping,but struggles on spirit run(I get vapor coming out even though the 1/2 pipe is cold at outlet). Which is why i went smaller tubes with a twist. 3 x 3/8(twisted) in an 1" tube would be ideal i think.

Good point. I run this condensor on my vacuum still, mostly for polishing my hydrous ethanol. The beauty with vacuum(with my setup) is that if there is a leak or blockage, the vacuum would disappear as would the boil, i run about 22hg with boil at approx 45c.
