Catalog excerpts

The TZ-74 rotary jet head provides 360° indexed impact cleaning over a defined time period. It is automatic and represents a guaranteed means of achieving quality assurance from cleaning tanks. Processing, storage and transportation tanks and vessels between 50 and 500m3 (13 000 and 131 000 US gallons). Used in breweries, food and dairy processes, chemical and many other industries. The TZ-74 rotary jet head has been particularly suitable and successful in the brewing industry worldwide. OPERATION The flow of the cleaning fluid makes the nozzles perform a geared rotation around the vertical and horizontal axis. In the first cycle, the nozzles lay out a coarse pattern on the tank surface. The following cycles make the pattern gradually more dense until a full pattern is reached after 8 cycles. CYCLE CHARACTERISTICS CLEANING IN PLACE First Cycle Full Cycle 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 clean. OPTIONS The choice of nozzle diameters can optimise jet impact length and flow rate at the desired pressure. An electronic rotation sensor to validate 360° coverage can also be included. ORDERING INFORMATION Please specify nozzle size and inlet/guide configuration connections.
