I’ve got this lovely Alfa laval Ac-70x-62m brazed plate heat exchanger. Snagged it for a “cool” $150 and it looks like it’s barely ever seen use.
I was thinking about making a little falling film evaporator (I hate my rotavap) for ethanol, and was curious if anyone had used these brazed plates before.
My first and easiest thought was just to use cold water in and out and call it a day. But I realized it’s built for refrigerants, and was curious if there’s a more self contained setup that might be worth building? Maybe dissasembling an old freezer or something?
I have the capacity to build a co2 expansion system for it, but it’s wayyyy overkill for my smaller needs at the moment.
Anyone got any tips?
