- Mar 25 2:12 PMI agree with what you found. I have further increased my efficiency using stainless compression springs that I put inside the waterjacket prior to seailing it up and that causes the water to swirl in the condenser eliminating any hot spots. I also put a spring inside the condenser tube which does the same thing and eliminates the ocassional surges you get in the vapor.I also put a coupeling between the condenser and the output tube for disasembly and cleaning with a brush which should be done after EVERY first distillation to remove the sulfide and carbonacious deposits. Alot of people dont clean and complain about strange off flavors!From: tgfoitwoods <zymurgybob@...>

Subject: [Distillers] Re: Graham condenser or liebeg condenser
I'm also Liebig user, and I've made and used several of them. 1/2 in 3/4 has always worked well for me, although I've built one with internal water-cooled cross-tubes that was 24" long, but worked like a 30".
One nice thing about a plain Liebig that you can't say about a Graham or crimped Liebig: it will work at any angle up to almost level. The other condensers will pool and burp when they get far from vertical.

I can run the cooling water quite slow on the stove top still. That model has a 3/4" copper riser running through a tee, out the side to a 45Â° and then to the condenser. The top of the tee has a thermometer port.

Hardly at all on the Bok. its only a product chiller before the parrot. Unless I turn the heat up too much on the big pot. But that just forces more water to jump.
