why 69*C?? Ethanol is about 10 degrees higher than that.
one issue with using a PID is the content in the boiler is not at a steady state. The ratio of ethanol : water changes through the run. simple on/off might work - I can't comment if it'll yet but its on my list to try. you will need to set a very small offset so you don't get wild swings above & below your set point.
that evil bay deal looks pretty good for the price.
Sorry typo **~79C**
I would set the tolerances quite low, say +/-0.2C. The change in water / ethanol mix would be accounted for through this method.
I have a spare AC fan lying around. Purchased a good quality 2nd hand ammo box today, just like the one in the pics above.
I might give the PID set-up a try. I have worked with them before for other applications with good control. For that price it won't be an epic fail if it doesn't work. Will let you all know.
hey Antamo, did you get around to trying this, or has anyone else tried it.
im thinking it should work, as vapour temp mostly reflects alc%.
so if you wanted your bourbon pulled out at 75%, you could set the pid to lets say84c vapour temp.
should make tails easier to define aswell, like when pulling nuetral out.
