Alfa Laval TZ-74 Rotary Jet Head


The Alfa Laval TZ-74 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. The device is suitable for processing, storage and transportation tanks and vessels between 50 and 500 m3 (13,000 to 130,000 US gallons). Used in breweries, food and dairy processes and many other industries. The TZ-74 rotary jet head has been particularly successful in the brewing industry worldwide.

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.

Standard Design

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