How does a Rotary jet head tank cleaning machine work?
Rotary jet heads use an optimized high-impact jet pattern to provide the highest possible coverage to achieve the best possible cleaning results. 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 increase coverage until, after eight cycles, the entire tank interior surface is thoroughly cleaned. The high jet pressure efficiently removes residue to meet the strictest production requirements.
TJ rotary jet head
Alfa Laval’s range of rotary jet head tank-cleaning devices provide exceptional cleanability, better end-product quality, greater overall output and up to 70% reduction in operating costs. They are designed for hygienic applications, such as food, dairy, personal care and beverages.
Benefits of the TJ series
- High impact quality assured tank cleaning in a 360° repeatable cleaning pattern
- Avoid contamination with effective cleaning performance and superior self-cleaning features
- Cost efficient and sustainable solution due to reduced water and chemicals requirements

- Control of CIP through validated cleaning
The TJ range of rotary jet heads provides automated 3D-indexed impact cleaning over a defined time period for processing, storage and transportation tanks and other vessels between 15 and 500 m³. The award-winning design is suitable for cleaning brewing equipment as well as for food and dairy processes and is a cost effective means of achieving hygienically safe, quality assured tank cleaning.
How does the TJ rotary jet head work?
The flow of the cleaning fluid makes the nozzles of the rotary cleaner 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 of our automatic tank cleaning equipment 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.
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%*
- *Compared with traditional static spray ball cleaning

Barrel/Drum/IBC rotary jet heads
The Alfa Laval GJ 7, Alfa Laval GJ BB and Alfa Laval GJ 9 rotary jet head tank cleaning devices represent a major technological breakthrough, offering the most powerful cleaning results in a compact, easy to handle size. The Alfa Laval GJ 7 and Alfa Laval GJ BB are specially designed to clean small barrels and drums, while the Alfa Laval GJ 9 offers fast cleaning of your intermediate bulk containers (IBC). All devices are available in a wide range of sizes and nozzle configurations.
Benefits of the Alfa Laval GJ range
- Faster cleaning time = More production time
- Reduces water/wash fluid usage for tank cleaning, leading to reduced cost to clean
- Eliminates the need for confined space entry for manual tank cleaning
- Durable and reliable, rotary jet heads are proven to boost cleaning efficiency by providing reliable and repeatable cleaning performance
A quality product
The Alfa Laval GJ tank cleaning devices are part of our highly acclaimed Gamajet product range. Alfa Laval technology combines pressure and flow to create high impact cleaning jets that are precision engineered to rotate in a precise, repeatable and reliable 360-degree pattern.
Application highlights
The Alfa Laval GJ 9 is ideal for cleaning IBCs and small vessels in 4–8 minutes. The unit fits openings as narrow as 76mm (3”) and operates efficiently at both low (3 bar) and high (70 bar) pressure. The Alfa Laval GJ 7 and GJ BB clean drums and barrels in 2–7 minutes using minimal wash fluid. Their compact design allows entry through openings as small as 55mm (1.75”), and they are ideal for residues like adhesives, paints, chemicals, and petroleum.
Positive return on investment
The unique design reduces your cost to clean and environmental footprint by minimizing the amount of water, energy and cleaning agents required. Replacing traditional static spray balls with high-impact rotary jet cleaning improves resource efficiency and performance.
How it works
High-impact, low-resource cleaning
The high-impact jet stream from the rotary jet head is preprogrammed to cover the inside of the tank in a continuously denser pattern. This achieves a powerful mechanical impact with a low volume of water, acid or caustic. Most of the Alfa Laval GJ rotary jet heads are capable of operating at both high and low pressures.
Smoother, long-lasting performance
The Alfa Laval GJ range includes a unique, grease-lubricated gear to ensure that potentially damaging particles are not trapped in the gear during CIP recirculation. This innovative design ensures a smoother performance and reduces wear and tear.
Energy-efficient design
A faster tank cleaning cycle also cuts energy consumption. Cleaning fluid flows through the nozzles in an automated, geared rotation around the vertical and horizontal axes. In the first cycle, the nozzles lay out a coarse pattern on the tank surface, with subsequent cycles progressively densifying the pattern over the course of eight cycles.
