GJ 5 Tank Cleaning

Application

The Alfa Laval GJ 5 offers compact cleaning for small-sized tanks, vats, and vessels. This device is designed for cleaning tanks 4.6 m (15 ft.) in diameter by 4.6 m (15 ft.) high and can easily fit through 7.62 cm (3 in.) openings. By switching from costly manual cleaning and time-intensive spray balls to the Alfa Laval GJ 5, companies are able to save a substantial amount of time, water, and money. The device is part of the world-renowned Gamajet range of high impact tank cleaning devices.

Working principle

The Gamajet range of high impact tank cleaning devices combine pressure and flow to create high impact cleaning jets. Cleaning occurs at the point at which the concentrated stream impacts the surface. It is this impact and the tangential force that radiates from that point which blasts contaminants from the surface, scouring the tank interior. In conjunction with this impact, the device is engineered to rotate in a precise, repeatable and reliable, 360° pattern. This full-coverage, global indexing pattern ensures the entire tank interior is cleaned, every time.
