, Premier Stainless
, and Quality Stainless
are just a few for fermenters. DME
is a good company for the brewhouses (and everything else). So is Bavarian Brewery
. There are many more but I agree with the last poster, probrewer is probably a better resource and might give you more info on specifics. Also, there's a group on this site called "Going Pro" for people moving up into the professional ranks. Check the link in my sig.
