Introduction To GJ 9

The high-impact jet streams from the Alfa Laval GJ 9 rotary jet head cover the entire surface of the interior of IBCs and tanks in a successively denser pattern. This achieves a powerful mechanical impact with a low volume of water and cleaning media. The flow of the cleaning fluid makes the nozzles perform a geared rotation around the vertical and horizontal axes. In the first cycle, the nozzles lay out a coarse pattern on the tank interior. The subsequent cycles gradually increase the pattern density. Once the full cleaning pattern is achieved, the machine will begin a new cycle of the full cleaning pattern.The above drawings show the cleaning pattern achieved on a cylindrical horizontal vessel. The difference between the first cycle and the full pattern is due to the additional rotations of the machine that gradually increase the density of the cleaning pattern.
