Re: Power/balancing for azeotrope questions
- Hi Mason,
Why always go with rubber seals on your boiler connections, you can use inert good old fashioned fibre seals/leather seals, just as well, they've been around for a very long time and work extremely well.
When they get wet they expand within minutes and seal the join. They've been used for hot and cold tap connections for years and years. They've also been used quite safely with electric kettles and emersion heaters for years and years and no leaks.

> I run a 1440 watt(120v) element with my rig for the run. No controller and it works great. There is also a 3800watt(220v) element ran on 120v for a measured 925watts that i use with the 1440 for initial heat up the pull the plug on the 925w element. I tried the 925w for the spirit run but didnt get the purity that I can with the 1440w. Reflux Ratio.
