Round, Conical-Bottom, 'Nestable' Tanks
Round, Conical-Bottom, Nestable Tanks

These tanks have all the benefits of our flat-bottom tanks with the advantage of a conical bottom. A 20 degree cone-bottom forces high solids to be removed from the bottom continuously. This allows for our tanks to be self cleaning for months at a time.
