The Alfa Laval TJ range of rotary jet heads for your tank cleaning needs

Effective tank cleaning with low operating costs

The strong jet generates a high mechanical force and covers 360° to efficiently remove remaining products and residues and provide the best hygienic conditions for production. As the force generated by the rotary jet head increases, the water consumption decreases, which leads to significant cost savings as illustrated in the diagrams. (based on Dr. Sinner’s cleaning philosophy.

  • Cost savings (water, chemicals): 70%*
  • Time saving = more production time: 60%*

How it works


Dynamic tank cleaning machines

The flow of the cleaning fluid makes the nozzles rotate around the vertical and horizontal axes. In the first cycle, the nozzles deposit a coarse pattern on the tank surface. Subsequent cycles gradually add density to the pattern, until full coverage is reached after eight cycles. The operation is fully automatic and provides users with effective quality assurance guarantees in tank cleaning, complete with all the necessary documentation.

Complete self-cleaning system

Not only does the Alfa Laval TJ range of rotary jet heads provide spotless cleaning of the tank interior, it also cleans itself – inside and out. The hygienic self-cleaning design ensures that the flow of the cleaning fluid covers the external surfaces of the rotary jet head to reduce the risk of cross contamination and potential product loss or recalls.


1. Overlap ensures self-cleaning of the body

2. The nozzle’s concave shape ensures self-cleaning of the nozzle itself

3. Through two holes in the hub, jet streams ensure cleaning of the cone




Low pressure drop

The low pressure loss over the machine results in increased cleaning efficiency compared with other tank cleaning machines running at the same inlet pressure. This results in lower cleaning costs as the unit can run at lower pressure/flow.
