kyFast, Effective Impact CleaningAlfa Laval TJ TZ-74 Self Cleaning Version Rotary Jet Head

.

ApplicationThe Toftejorg TZ-74 Self Cleaning Version rotary jet head provides 3Dindexed impact cleaning over a defined time period. It is automaticand represents a guaranteed means of achieving quality assurancein tank cleaning. The device is suitable for processing, storage andtransportation tanks and vessels between 50 and 500 m3. Used inbreweries, food and dairy processes and many other industries witha strict demand for self cleaning of the machine and the downpipe.The Toftejorg TZ-74 Self Cleaning Version rotary jet head has beenparticularly successful in the brewing industry worldwide.

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.

Standard DesignThe choice of nozzle diameters can optimise jet impact length and flow rate at the desired pressure. As standard documentation, the Toftejorg TZ-74Self Cleaning Version can be supplied with a “Declaration of Conformity” for material specifications.

TRAX simulation toolTRAX is a unique software that simulates how the Toftejorg TZ-74 Self Cleaning Version performs in a specific tank or vessel. The simulation givesinformation on wetting intensity, pattern mesh width and cleaning jet velocity. This information is used to determine the best location of the tank cleaningmachine and the correct 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 tank cleaningapplications. A TRAX simulation is free and available upon request.
