. ky Award-Winning Design Toftejorg TJ 20G Rotary Jet Head . Application The Toftejorg TJ 20G rotary jet head provides 3D indexed impact cleaning over a defined time period. It is automatic and represents a guaranteed means of achieving quality assurance in tank cleaning. Used in breweries, food and dairy processes and many other industries, the device is suitable for processing, storage and transportation tanks and vessels between 15 and 150 m 3 (4,000 to 40,000 US gallons). The award-winning design is particularly suitable for hygienic industries that follow European Hygienic Equipment Design Group guidelines. Working principle 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. The subsequent cycles gradually make the pattern more dense, until a full pattern is reached after 8 cycles.

ApplicationThe Toftejorg TJ 20G rotary jet head provides 3D indexed impactcleaning over a defined time period. It is automatic and represents aguaranteed means of achieving quality assurance in tank cleaning.Used in breweries, food and dairy processes and many otherindustries, the device is suitable for processing, storage andtransportation tanks and vessels between 15 and 150 m3 (4,000 to40,000 US gallons). The award-winning design is particularly suitablefor hygienic industries that follow European Hygienic EquipmentDesign Group guidelines.
Working principleThe flow of the cleaning fluid makes the nozzles perform a gearedrotation around the vertical and horizontal axes. In the first cycle, thenozzles lay out a coarse pattern on the tank surface. The subsequentcycles gradually make the pattern more dense, until a full pattern isreached after 8 cycles.
Cleaning Pattern
First cycle Full pattern
The above drawings show the cleaning pattern achieved on acylindrical horizontal vessel. The difference between the first cycle andthe full pattern represents the number of additional cycles available toincrease the density of the cleaning.
Standard DesignThe choice of nozzle diameters can optimise jet impact length and flowrate at the desired pressure. The Toftejorg TJ 20G is also available withPEEK impeller. A welding adaptor with sealing for 1” ISO, 1” ANSI, 11/2” ISO Dairy Pipe or 1 1/2” SWG Pipe is available as an accessory.The sanitary construction of the Toftejorg TJ20G is designed, with theaim to meet both European and American standards and regulations,such as EHEDG, USDA, USFDA, 3A etc. The TJ20G has been testedaccording to the EHEDG test procedure on cleanbility and in-linesteam sterilisability. As standard documentation, it can be suppliedwith a "Declaration of Conformity" for material specifications.Special distillery version available - see ordering leaflets.

OrderingPlease specify nozzle size and required connections and confirmapplication suitability
Sizing/selection and installation drawings are available in Alfa Laval’sSelection Tools for Tank Cleaning Equipment.
OptionsElectronic rotation sensor to verify 3D coverage.
TRAX simulation toolTRAX is a unique software that simulates how the Toftejorg TJ 20G performs in a specific tank or vessel. The simulation gives information on wettingintensity, pattern mesh width and cleaning jet velocity. This information is used to determine the best location of the tank cleaning machine and thecorrect combination of flow, time and pressure to implement.
A TRAX demo containing different cleaning simulations covering a variety of applications can be used as reference and documentation for tankcleaning applications. The TRAX demo is free and available upon request.
