GJ BB Tank Cleaning

Application

The Alfa Laval GJ BB is part of the world-renowned Gamajet range of tank cleaning devices. With a single insertion of the Alfa Laval GJ BB, barrels and 208.2 l (55 gal) drums are cleaned in only 2-3 minutes while using only 30-45 l (8-12 gal) of water. This device offers high-performance cleaning combined with maximum durability. A heavy-duty stainless steel gear train remains outside the barrel or drum during cleaning, ensuring a long service life. The Alfa Laval GJ BB saves companies substantial amounts of time, water, and money.

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.
