ky Alfa Laval TJ20G Award-Winning Design Application The Toftejorg TJ20G 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 m3. 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. .

In general, a filter in the supply line is recommended. Do not use for gas evacuation or air dispersion. For steaming we refer to the manual. First cycle Full pattern The above drawings show the cleaning pattern achieved on a cylindrical horizontal vessel. The difference between the first cycle and the full pattern represents the number of additional cycles available to increase the density of the cleaning.

Standard Design The choice of nozzle diameters can optimise jet impact length and flow rate at the desired pressure. The Toftejorg TJ 20G is also available with PEEK impeller. A welding adaptor with sealing for 1” ISO, 1” ANSI, 1 1/2” ISO Dairy Pipe or 1 1/2” SWG Pipe is available as an accessory. As standard documentation, it can be supplied with a "Declaration of Conformity” for material specifications. Special distillery version available - see Price lists. TRAX simulation tool TRAX is a unique software that simulates how the Toftejorg TJ20G performs in a specific tank or vessel. The simulation...
