ok so I might be getting my hands on some Perlick 2 faucet towers that are glycol cooled.
I have no idea about glycol cooling, do I need to use glycol with these towers? They will be sitting right on top of my keezer, can I just use air through the glycol lines instead?
No you don't have to use glycol. I just got a small 2 tap kegerator/with a tower, it pours fine with no tower cooling at all, at 42F. I'm a bit surprised by this, as my other kegerator (chest freezer) needs a fan.
I can now build my keezer with granite tile and nice tower faucets and wee little ones can't pour beer all over the ground.
