. ky Superior tank cleaning for industrial environments Alfa Laval GJ 4 . Application The Alfa Laval GJ 4 is part of the world-renowned Gamajet range of high impact tank cleaning devices. The device provides high-impact cleaning for large-sized tanks with diameters over 4.6 m (15’). This device is fully capable of high-concentration chemical recirculation cleaning and high-pressure, low-volume water jet scrubbing in fixed, automated CIP systems. The Alfa Laval GJ 4 is designed to remove the toughest residues from large tanks in numerous industries and is customizable in a wide variety of ways. The Alfa Laval GJ 4 allows companies to spend less time cleaning and more time producing. 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. TECHNICAL DATA Lubricant ...................

Standard DesignThe choice of nozzle diameters can optimize jet impact length and flow rate at the desired pressure. As standard documentation, the Alfa Laval GJ 4can be supplied with a “Declaration of Conformity” for material specifications.
TRAX simulation toolTRAX is a unique software that simulates how the Alfa Laval GJ 4 performs in a specific tank or vessel. The simulation gives information on wettingintensity, pattern mesh width and cleaning jet velocity. This information is used to determine the best location of the tank cleaning device and the correctcombination of flow, time, and pressure to implement.A TRAX demo containing different cleaning simulations covering a variety of applications can be used as a reference and documentation for tankcleaning applications. The TRAX demo is free and available upon request.
