kyAlfa Laval GJ PF
Fast, Effective Impact Cleaning
.
ApplicationThe field-proven Alfa Laval GJ PF is part of the world-renownedrange of Gamajet high impact tank cleaning devices. It has beenproven to provide companies with up to 85% in water, time, energy,and resource savings compared to static spray balls. This device iscapable of cleaning tanks with capacities between . The Alfa Laval GJPF fits through openings as small as and operates at low pressuresand flows, cleaning tanks in the ethanol, paper, pulp, chemical, steel,industrial fermentation industry, and many other applications thatrequire high impact cleaning. By implementing this device into theirtank cleaning process, companies spend less time cleaning and moretime producing.
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 PFcan be supplied with a “Declaration of Conformity” for material specifications.
TRAX simulation toolTRAX is a unique software that simulates how the Alfa Laval GJ PF 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.
