kyPowerful tank cleaning for small barrels and drumsAlfa Laval GJ 7
.
ApplicationThe smallest rotary impingement tank cleaning device, the Alfa LavalGJ 7 easily fits through a 3.8 cm (1.5”) access hole. Capable ofoperating at both high and low pressures, this device delivers 2.27 kg(5 lbs.) of cleaning force at .76 m (2.5 ft.) The Alfa Laval GJ 7 offersquick and easy cleaning of barrels, drums, and other small vessels in awide variety of industries. The device is part of the world-renownedGamajet range of high impact tank cleaning devices.
Working principleThe Gamajet range of high impact tank cleaning devices combinepressure and flow to create high impact cleaning jets. Cleaning occursat the point at which the concentrated stream impacts the surface. Itis this impact and the tangential force that radiates from that pointwhich blasts contaminants from the surface, scouring the tank interior.In conjunction with this impact, the device is engineered to rotate ina precise, repeatable and reliable, 360° pattern. This full-coverage,global indexing pattern ensures the entire tank interior is cleaned,every time.

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 7can be supplied with a “Declaration of Conformity” for material specifications.
TRAX simulation toolTRAX is a unique software that simulates how the Alfa Laval GJ 7 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.
