I'm in need of an open top tank that can be used as a CIP grant, something with a TC outlet at the bottom and another TC inlet higher up on the tank to recirculate back into. I'd like to be able to make about 1 barrel of caustic or acid or whatever in it and circulate through various equipment, without spending $6k+ on an electric CIP cart.

Anybody looking to get rid of something like this or have a suggestion where to look?
