ky Powerful tank cleaning for small barrels and drums Alfa Laval GJ 7 Application The smallest rotary impingement tank cleaning device, the Alfa Laval GJ 7 easily fits through a 3.8 cm access hole. Capable of operating at both high and low pressures, this device delivers 2.27 kg. of cleaning force at .76 m. The Alfa Laval GJ 7 offers quick and easy cleaning of barrels, drums, and other small vessels in a wide variety of industries. 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.

Standard Design The choice of nozzle diameters can optimize jet impact length and flow rate at the desired pressure. As standard documentation, the Alfa Laval GJ 7 can be supplied with a “Declaration of Conformity” for material specifications. TRAX simulation tool TRAX is a unique software that simulates how the Alfa Laval GJ 7 performs in a specific tank or vessel. The simulation gives information on wetting intensity, pattern mesh width and cleaning jet velocity. This information is used to determine the best location of the tank cleaning device and the correct combination 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 tank cleaning applications. The TRAX demo is free and available upon request. . Wetting Intensity
