The freezing point of the 66:33 water/methanol blend is about
-40 DegC so I don't see that as a problem. I'm sure I won't be venturing that low as much as I'd like to
. I started on my evaporator today. I'm using a small bulb 2"x3" as the initial point of contact for the liquid freon. It will then be sent through the 1/4" copper tubing. I'm hoping the extra volume the bulb provides will help me drop the temperature of the liquid.
