Application
The Alfa Laval Gamajet 9.2 tank cleaning device fits through a 50 mm (2″) opening and is capable of cleaning above- and below ground fuel storage tanks with capacities up to 4,750 I (1,2 50 gallons). This device blasts away contaminants and breaks up dirt and sludge in minutes. Diesel fuel can be used as the cleaning agent, which saves time and mitigates contamination and waste disposal.

Cleaning Pattern
The above drawings show the cleaning pattern achieved on a cylindrical horizontal vessel. The difference between the first cycle and the full pattern represents the number of additional cycles available to increase the density of the cleaning.
Working principle
The Alfa Laval Gamajet 9.2 tank cleaning device combines 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.
