      I purchased a 2.5 gal air cooled still, and it has a single 15" section of fins.  Indoors it is not a great place to use it, because it requires 2 if not 3 fans to cool vapor.  If a person were to add at least 2 to 4 more 15" fines it would be ideal to use with 1 small fan.  I can't recommended the company where I purchased mine because their called stainless steel pot flake and start leaking after 5 runs.  Ask someone in HVAC about a small cooling radiator and fan, because it's a lot easier then hooking up a worm and water pipes and hoses.

      Subject: [Distillers] Air cooled still

       
      Living in the 'great cold North', water isn't always the most convenient thing to use when distilling.  Like when it's cold enough to freeze the hoses running to the condenser...quite the "Oh sh!t" moment, I assure you.    So, I started to wonder...could this be air-cooled?
      Some basic research revealed that the concept is solid; it just takes quite a bit more of a copper coil for the task. How much is really the question...there really isn't much info available on the thermal transfer properties of condensate-copper-air :p.
      Coincidentally, I found that I might have some very inexpensive access to 1/2" copper coil. Is it reasonable to assume that if I was to make a condenser coil out of 50 ft of said copper (minus some for running to the still head) with a fan blowing over it, I should be able to run a strip? For ambient temperatures under 70F, at least.
      Thanks in advance,

        On page 17 of his book Designing and Building Automatic Stills, Riku describes air-cooling a condenser on a potstill, and I know he's been using air-cooling for years. The book is available from the publisher, Amphora Society, and from me at kelleybarts.com. For those who don't know Riku or his book, and want to really push the technology, this is a great book.

        He's got his own forum going. mostly among Scandinavians.

        If you used a properly designed condenser, you will never want to use a worm again. Robert ________________________________ From: tgfoitwoods

            I just remodeled the plumbing on an old house. In the process I removed a few 8 feet sections of 3/4 inch radiant base board heaters. It's just thin wall 3/4" copper tube that has aluminum fins covering it.
            I was thinking about using it for an air condenser. I had a idea to put a 1/2" copper tube down the middle as to push the vapor to the sides. But maybe it would be counter productive? Help hold the heat in?

              I would cut 5 - 18" pieces, and connect them together with pipe, elbows, tees, and cross joints, in the shape of a compact radiator.  Make sure it's placed vertical to empty properly and placing legs on it would be a good idea too.  Place a fan behind radiator to improve heat dissipation is wise.

                Tim,

                I would think your find should have all the advantages of Riku's finned aluminum, and the benefits of copper as well. Lots of distillers will introduce turbulence into a large straight condenser tube (to avoid laminar flow, it's it's loss of efficiency) by simple pulling a few loose strands of common copper "scrubby" into the condenser. It doesn't take muck, and you don't want much. Use a magnet to be sure that scrubby is 100% copper; many are not.

                Good luck with the air-cooling, and keep us posted.

                  I've an idea to run it down a ductwork which I can run a hi flow fan through.

                  Scrubbers or even a thin copper strip for the first little bit sounds good.

I number the jars in advance, cover with a paper towel and a rubber band.( some use coffee filters ) and mark each in my log with the head temp and ABV. I let it air overnight, and then convince my girlfriend, who has better nose and tastebuds than I to do the nose and teaspoon test.  Just like wine tasting, she spits it out.

                          Since, my old still failed twice in 3 months, I will have my next still built according to my specification, and it will use a self designed air cooled radiator made of copper pipe, aluminum fins, and a single fan.
