Alfa Laval TJ20G and TJ40G Rotary Jet Head tank-cleaning devices provide exceptional cleanability, better end-product quality, greater overall output and reduced operating costs. They are designed for hygienic applications, such as food, dairy, personal care and beverage.

Effective tank cleaning with low operating costs

The high mechanical force generated by the strong jet impingement, efficiently removes remaining products and residues to provide the best hygienic conditions required for production.

Blue = Water consumption/time
Red = Mechanical action 

Yellow = Temperature Grey =Chemicals

When the mechanical force, generated by the rotary jet head (Alfa Laval TJ20G or TJ40G) increases, the water consumption is decreasing, which leads significant cost savings as illustrated above, which is based on Dr. Sinners cleaning philosophy.

  • Cost savings (water, chemicals): 70%*
  • Time saving = more production time: 60%*
    *compared to traditional static spray ball cleaning

 Tank cleaning machine with complete self-cleaning system

Not only does the Alfa Laval TJ range of Rotary Jet Head provide spotless cleaning of the tank interior, it also cleans itself – inside and out. Its hygienic self-cleaning construction ensures that the flow of the cleaning fluid reaches the external surfaces of the rotary jet head. This reduces the risk of cross contamination and potentially 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

How it works

Dynamic tank cleaning machines

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 coarse pattern on the tank surface. Subsequent cycles gradually make the pattern more dense, until a full pattern is reached after eight cycles. This all takes place automatically and provides users with an effective path to quality assurance guarantees in tank cleaning, complete with all the necessary documentation.
Alfa Laval rotary jet heads are ideal for cleaning processing, storage and transportation tanks and other vessels used in process, sanitary, pharmaceutical and other industries
