The Alfa Laval MultiJet is a rotary jet head tank cleaning machines for use in industrial environments. Built to clean tanks with capacities from 50 to 7000 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 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.
Built to clean tanks with capacities:
- Model MJ40: 50 - 500m³
- Model MJ50: 250 - 1250 m³
- Model MJ65: 3000 - 7000m³
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
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. 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.
