Introduction
|
| The Alfa Laval MultiJet 45 is a rotary jet head tank cleaning machines for use in industrial environments. Built to clean tanks with capacities up to 500 m3 it combines pressure and flow to create high-impact cleaning jets that rotate in a repeatable and reliable 360- degree cleaning pattern |
| The MultiJet 45 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 45 is designed for the removal of the toughest residues from industrial tanks across a broad range of industries, such as the chemical, pulp and paper, ethanol, starch, oil. |
| |
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
- Allows re-circulation of CIP media with particles in, up to 3 mm particle size
- Robust and durable design

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. An alternative that offers performance similar to the Alfa Laval MultiJet 45 is the Alfa Laval GJ 8 for applications that require a small tank inlet opening. |
| 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 45 rotary jet head covers the entire surface 360° 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. |

Caution
|
| Avoid hydraulic shock, hard and abrasive particles above 3 mm in the cleaning liquid, as this can cause increased wear and/or damage of internal mechanisms. In general, a filter in the supply line is recommended. Do not use for gas evacuation or air dispersion. For steaming we refer to the manual. |
