Re: Compact Air Condenser

Finally got a piece of pipe soldered up. The adapter is a 2" bushing, which has the same OD as a piece of 2" pipe. This fits right into the connector I have at the top of the column. http://i.imgur.com/UkO0VvK.jpg I used some acrylic sheet that I had to build the frame. I screwed two lengths of alum...

Re: Compact Air Condenser

I thought they were 12 vdc fans like most computer fans. no problems If you wanted temp control those pc fan controllers are great and the 12vdc fans are in everything.

Re: Compact Air Condenser

Go with pwm for your fan controller. I messed around a lot with pwm for my stir plate build. EBay has descent controllers quite cheap. Around $10 I can get you a link if you want. Look at the 5 1/4 bay computer fan controllers. Everything you could ever want including temp control and rpm readout. ...

Re: Compact Air Condenser

This is one of those do-it-yourself radiant heater fins. It's 12" long, 4" wide and fits around a 1-1/4" pipe. It is claimed to radiate 1500 + watts of heat per foot (without forced air). That looks nice but the specs I found say 1527 BTU which a BTU to Watt converter turned into 447.52 watts. Than...

Re: Compact Air Condenser

I don't think you have grasped how the peltier works. When you plug it in it acts like a heat pump, one side gets hot and the other side gets cold. The way I have drawn it out it is the heating source for the boiler and cooling source for the condensor. There are no other heaters or fans although, ...

Re: Compact Air Condenser

http://homedistiller.org/forum/download/file.php?id=37428&t=1 Interesting idea. I guess that the hot side of the peltier would have to be considerably hotter that the boiler temp in order for efficient heat extraction. If you can put one on an exhaust pipe, a boiler should be no problem. A good rec...

Re: Compact Air Condenser

I understand. I think peltiers have a lot of potential but the price was way high. I'm gald that my info was outdated and they seem to have come down a lot. Just spotted a 62mm 545w peltier on ebay for $41. One thing that I can't get out of my mind is that one side gets hot and the other cold. You ...

Re: Compact Air Condenser

I just threw those out to stimulate thinking. Peltier cooling is probably not practical, but it would be fun to mess with.

Swag, You are the MAN! You are single handedly pushing ahead the boundaries of hobby distilling.

Re: Compact Air Condenser

I didn't think aluminum and alcohol got along well. Am I wrong there? The other issue would be sealing the whole thing up. One of the reasons I built it this way was to have a sealed system without having to build a box, because they're a pain. Anyone with a drill press and a hack saw could build th...

I'm glad you guys like it, it's been fun to build.

Re: Compact Air Condenser

Hey thanks, I was happy with the results. Water is tougher than alcohol to knock down, so I feel confident that I can use this condenser in any application. The exit water temperature was also lower than I expected, which was a pleasant surprise. It's nice to have some buffer in case the ambient air...

For ethanol it is 846 KJ/Kg, water is 2257 KJ/Kg. Good to know anyway. I suppose I could do some highly complex calculations to determine the actual heat dissipation potential of my rig, but it's much easier to just see if we have liquid coming out of the business end, and how hot it is.
