You don't need two elements in a 30 litre keg, I have a 50 litre keg boiler and I only need one 3.5kw element, it can bring a 40 litre wash to boil in 45 mins.
Also 4" column connection is probably too big also, if it's 30 capacity you probably won't fill it more that 20-25 litres, with low wines at 30% you will have 6-7.5 litres of alcohol in there, a 2"'column would be perfectly sized, at 1.5 litres an hour your looking at a 4-5 hour spirit run, plus heat up time, which is not unreasonable, I would suggest if your keg has a standard fitting, then a 2" tri-clamp will connect directly to it.
If you want a bigger column, just get a tri-clamp adapter from 2"-4"
I took my keg to a local place near me to have a 4" ferrule connection welded in for the column and one 2" triclamp ferrule in the side for the heating element, have a look around your local industrial estate, there's bound to be a company that has a fabrication workshop who could do the work, I supplied the keg and ferrules and it cost about £20 to get them welded on.
You may also want a bottom drain, this you can fit yourself, if you search boat deck skin fittings, you'll find fittings you can install in the bottom that you can connect a drain pipe and tap to.Statistics: Posted by Anavrin — Sat Mar 25, 2017 12:11 am
