kySave time and water with single-insertion barrel cleaningAlfa Laval GJ BB

.

ApplicationThe Alfa Laval GJ BB is part of the world-renowned Gamajet range oftank cleaning devices. With a single insertion of the Alfa Laval GJ BB,barrels and 208.2 l drums are cleaned in only 2-3 minutes while usingonly 30-45 l of water. This device offers high-performance cleaningcombined with maximum durability. A heavy-duty stainless steel geartrain remains outside the barrel or drum during cleaning, ensuring along service life. The Alfa Laval GJ BB saves companies substantialamounts of time, water, and money.

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 BBcan be supplied with a “Declaration of Conformity” for material specifications.

TRAX simulation toolTRAX is a unique software that simulates how the Alfa Laval GJ BB performs in a specific tank or vessel. The simulation gives information onwetting intensity, pattern mesh width and cleaning jet velocity. This information is used to determine the best location of the tank cleaning deviceand 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 tankcleaning applications. The TRAX demo is free and available upon request.
