General Description
General Description
The SaniJet 25 is a media driven and media lubricated tank cleaning machine. No lubricating
substances such as oil, grease etc. are used. All materials complies with FDA 21CFR§177 and for
polymers also EU 10/2011, which makes the SaniJet 25 suited for sanitary and hygienic applications
such as Food and Pharmaceutical industry. If required the machine is also available with USP Class VI
materials from new or as an upgrade kit. The machine is self-cleaning; i.e. all internal and external
surfaces are cleanable, drainable and sterilizable.
The SaniJet 25 is a sanitary cleaning device of the rotary jet head type for permanent installation that
provides a 360° indexed cleaning pattern. Provided it is installed in a vertical position, the SaniJet 25 is
proven completely self-cleaning by the EHEDG test method and self-draining. Using the Sanitary
welding connection (included in the package) between down pipe and machine provides a self-
cleanable connection. All product contact surfaces are AISI 316L, duplex SAF 2205 stainless steel or
FDA compliant polymer and elastomer materials.
No exposed threads or screws are present in the product contact areas.
The SaniJet 25 is designed for use in pharmaceutical, biotechnology, food and dairy processing
applications. Recommended for use in tanks and vessels between 0.5-30 m
3
(130-8,000 US gallons)
for larger tanks multiple units may be used.
Quality system
The SaniJet 25 is designed in accordance with the EHEDG design guidelines for sanitary design of
processing equipment and is the first ever rotating jet head that has been awarded the certificate of
compliance from EHEDG, showing that the machine has passed the EHEDG test (Doc. 2) for
cleanability. In addition the machine is proven to be sterilizable based on EHEDG test (Doc. 5). It is
produced according to Alfa Laval Kolding’s ISO 9001 International Standard certified quality system. All
parts are made from certified material and all non-metal parts are made from FDA and EU compliant
materials and also available as USP Class VI materials. All materials has full traceability according to
EU1935/2004/EC
Functionality
The cleaning fluid passing through the machine passes through a turbine, which accordingly is set into
rotation. The turbine rotation is transmitted through a set of gears and drive shaft to the machine Body
and the Hub cover with Nozzles.
The combined rotation of the machine Body and the Nozzles ensure a fully indexed tank cleaning
coverage as illustrated below for a spherical tank with the machine placed in the centre. For light
soiling only 1 cycle could be sufficient and for heavier soiling a full pattern (8 cycles) may be needed.
One cycle provides a coarse pattern and is built from 5

revolutions of the Hub cover with Nozzles;
corresponding to 5

/
8
revolutions of the machine Body. During the following cycles, this coarse pattern
is repeated 7 times, each coarse pattern displaced slightly. Hence, the pattern gradually becomes
denser. Finally, after 8 cycles (a total of 45 revolutions of the Hub Cover with Nozzles and 43
revolutions of the machine Body), a complete cleaning pattern has been laid out, and the pattern starts
over from the original starting point.
