Re: Cooling water

I filled the blue drum up to the holes, say 40 gallons. Four and a half hours from when I first turned the power on. No alarm or fail-safe needed because I do not leave any still unattended. Thanks. A couple nore questions: Do you know how many CFM your 30W fan is rated for? Any idea how much tap-w...

Re: Condenser Controlled Columns

In the reflux condenser, filling as much if the tube with CSST coil is important. It blocks more vapor and provides a tight fit for holding the coil in place. For the dimroth style product condenser it is not as important. SS Scrubbie can be packed around a loose fitting twisted loop and the end ca...

Re: Soldering SS Ferule to Copper Troubles

I have never formed the solder ring when I solder, It doesn't mean that it is the only way I see many here get excellent results using the ring of solder I just think I get better control applying the solder as necessary .

Re: Soldering SS Ferule to Copper Troubles

If you have a good silver bearing solder which it looks like you do , 3.8 % silver and the stay clean flux I would use that. I have never had good luck with plain plumbers solder for stainless to copper connections. The silver bearing solder makes it sooooo much easier. Remember to clean all the pa...

Re: Soldering SS Ferule to Copper Troubles

Part of your issue with soldering the ferrrule is using the improper tools, cleaning and application.. All the part need to be properly sanded, cleaned, and the s.s. cleaned with acetone or lacquer thinner.. then prep with the properly paste, for s.s. Stay Clean liquid flux or Superior 71 paste (bo...

Re: Condenser Controlled Columns

fafrd, if you want to have a coiled RC go for the smallest size CSST, otherwise your RC will be the twisted version. The twisted version works fine for me. The important thing is that you can move the RC easily and that it stays in the position you wanted it. If the CSST is fitted with compression ...

Re: Condenser Controlled Columns

Maritimer...if you monitor the temp of the outflow coolant temp., and keep it below 140ish, you should be condensing 100% of the vapor, in the column and in the product condenser. With my setup, if I keep it below 130 Deg F, I know I'm o.k. I worked in photo labs for years and I know MY HANDS can t...

Re: Keg still tower design questions

And here’s an idea...make the column height several shorter sections. That way you can adjust the purity if desired for a lower off still proof for more flavor throughput. The additional TC clamps and ferrules are an opportune investment for future capability. An 8”, 16”, and 24” section will give ...

Re: Keg still tower design questions

With proper packing, a 1 meter or 40” (packed section) will get you azeotropic product provided you have a high enough reflux ratio. You can make it taller if you like, but the benefits of additional packing rapidly diminish. And the cost of the column (and packing) adds cost. Be sure to insulate t...
