Hi Kurt for one thing the Evaporator in the chiller is Titanium, a very

I like to tinker, so I think I'll just start building my own as time
permits.

btw, I'm sure titanium works great, but is it necessary? High grade
stainless won't corrode for years, it's cheaper, and much easier to work
with (titanium is brittle). At least, my tack on my sailboat doesn't
corrode and it's been on the beach for 4+ years. They also use it for
knee replacements that are good for 20+ years.
