GJ 8 Tank Cleaning

Application

Designed with ergonomics in mind, the Alfa Laval GJ 8 provides the same high impact clean as traditional, larger tank cleaners but is lighter, shorter, and narrower. This device is part of the world-renowned Gamajet range of high impact tank cleaning devices, and is the perfect alternative to heavy impingement cleaners, time-intensive spray balls, and costly manual tank cleaning. Compact and efficient, the Alfa Laval GJ 8 allows for space saving while maintaining the impact, durability, and range required for optimal impingement tank cleaning. This device is fluid-driven, eliminating the need for power assistance and is ideal for cleaning stubborn residues in large tanks in a variety of industries such as ethanol, paper, pulp, chemical, steel, industrial fermentation and many more applications requiring high impact cleaning. A 180 degrees directional nozzle also available.

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.

The GJ 4, GJ 5 and GJ 5 Directional Cleaning machines are designed specifically for cleaning all types and sizes of open-topped vats, tanks, and vessels. These versatile units are turbine-driven and provide 180° rotary impingement cleaning to easily clean the sides and bottom of virtually any size application. With these cleaning machines, you get the cleaning power you need, in the direction you need it. A choice of nozzle sizes, turbines and gear speeds offer a large range of flow rates, pressures and wash cycle times.

The 180° and 105° directional units still maintain Alfa Laval’s rotary impingement cleaning process. This process optimizes the water or cleaning solution driving the device, providing the maximum force from the jet stream leaving the nozzles and contacting the interior of the tank. The machine then moves the jet streams in a rotational pattern to cover the entire inside of the tank or vessel in a repeatable and reliable manner. The design of the machine not only ensures durability but efficiency as well. A minimal and controlled amount of leakage allows the machine to clean itself, while the majority of the fluid reaches the actual contour of the tank, scouring and cascading bit by bit.
