Introduction To GJ A2

The Alfa Laval GJ A2 is a rotary jet head tank cleaning machine designed for use in hygienic environments. Tailored for cleaning tanks with capacities ranging from 0.5 to 1.5 m³, this machine utilizes pressure and flow to generate high-impact cleaning jets that rotate in a repeatable and reliable 360-degree cleaning pattern. The GJ A2 is engineered to minimize water and cleaning media consumption, promoting efficiency. Additionally, its design allows for easy customization to meet specific customer requirements, enabling companies to optimize their cleaning processes and allocate more time to production.

GJ A2 Application

The Alfa Laval GJ A2 is designed for the removal of residues from hygienic tanks across a broad range of industries, such as the dairy, brewery, beverage, food, and personal care industries. Due to its slim design, the Alfa Laval GJ A2 is ideal to retrofit spray balls, thereby reducing Cleaning in Place (CIP) costs and cleaning time.

GJ A2 Benefits

High-impact cleaning in a 360degree repeatable cleaning pattern

60percentage faster cleaning equal more time for production

Saves up to 70percentage of your cleaning cost

Cleaning process can be validated using Alfa Laval Rotacheck

Slim design makes it possible to insert through small tank inlet openings

GJ A2 How It Work

The high-impact jet stream from the Alfa Laval GJ A2 rotary jet head covers the entire surface of the tank interior in a successively denser pattern. This achieves a powerful mechanical impact with a low volume of water and cleaning media. The flow of the cleaning fluid makes the nozzles perform a geared rotation around the vertical and horizontal axes. In the first cycle, the nozzles lay out a course pattern on the tank surface. The subsequent cycles gradually make the pattern denser until at full cleaning pattern is reached. Once the full cleaning pattern is reached, the machine will start over again and continue to perform the next full 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.
