. ky Alfa Laval MultiJet 40 Rotary jet heads . Introduction The Alfa Laval MultiJet 40 is a rotary jet head tank cleaning machines for use in industrial environments. Built to clean tanks with capacities from 50 and 500 m 3 it combines pressure and flow to create high-impact cleaning jets that rotate in a repeatable and reliable 360-degree cleaning pattern . The MultiJet 40 minimizes the consumption of water, and cleaning media. Easy to customize to meet customer requirements, it allows companies to spend less time cleaning and more time producing. . Application The Alfa Laval MultiJet 40 is designed for the removal of the toughest residues from industrial tanks across a broad range of industries, such as the home care, chemical, pulp and paper, ethanol, starch, oil, and transportation industries. . . Benefits • 60% faster cleaning = more time for production • Saves up to 70% of your cleaning cost • Eliminates the need for confined space entry for manual tank cleaning • High-impact cleaning in a 360° repeatable cleaning pattern • Cleaning process can be validated using Alfa Laval Rotacheck . Standard design The choice of nozzle diameters can optimize jet impact length and flow rate at the desired pressure. A 2.1 material certificate and an ATEX certification are available. . Alfa Laval offers a wide range of tank cleaning machines suitable for different duties and industries.

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 high-impact jet stream from the Alfa Laval MultiJet 40 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.

Working principleThe high-impact jet stream from the Alfa Laval MultiJet 40 rotaryjet head covers the entire surface of the tank interior ina successively denser pattern. This achieves a powerful mechanicalimpact with a low volume of water and cleaning media.
The flow of the cleaning fluid makes the nozzles perform a gearedrotation around the vertical and horizontal axes. In the first cycle, thenozzles lay out a course pattern on the tank surface. The subsequentcycles gradually make the pattern denser until at full cleaning patternis reached.
Once the full cleaning pattern is reached, the machine will start overagain and continue to perform the next full cleaning pattern.

TRAX simulation toolTRAX is a unique software that simulates how the Toftejorg MultiJet 40 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 machineand 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 reference and documentation for tank cleaningapplications. A TRAX simulation is free and available upon request.
