Optimize your tank cleaning process. Alfa Laval rotary impingement tank cleaning devices use patented technology that combine pressure and flow to create high impact cleaning jets. Cleaning occurs not just where the concentrated stream impacts the surface, but also through the tangential force that radiates from that point and blasts contaminants from the surface, scouring the tank interior. High-impact cleaning jets are delivered in a precise, repeatable and reliable, 360° pattern. This combination of impact in a controlled indexing pattern results in an economic ideal, because impact is a one time investment; chemicals, temperature and time are continual, never-ending expenditures.
