Toftejorg TZ-750 Rotary Jet Head - Portable

00001162
Fast, Effective Impact Cleaning
Toftejorg TZ-750 Rotary Jet Head - Portable

Application

The Toftejorg TZ-750 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 in tank cleaning. The device is suitable for storage and transportation tanks and vessels between 3,000 and 7,000 m3 (792,000 to 1,850.000 US gallons). Used in chemical processing and the pulp and paper industries.

Sizing/selection and installation drawing are available in Alfa Laval CAS tool for Tank cleaning equipment.

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 4 cycles.

Cleaning Pattern

First cycleFull pattern

The above drawings show the cleaning pattern achieved on a 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. As standard documentation, the Toftejorg TZ-750 can be supplied with a “Declaration of Conformity” for material specifications.
