1. Introduction
Scanjet model SC 40RT is a tank cleaning
machine especially developed for cleaning
of cargo and slop tanks onboard chemical/
product carriers. The size, construction and
cleaning requirements of these tanks are
design criteria, which have been evaluated
prior to installation in your application.
SC 40RT tank cleaning machine consists
of two main parts; a gun unit that is fixed
installed on the tank and a turbine driven
drive unit. The cleaning procedure will start
by opening the valve for cleaning media.
The drive unit will now rotate the bottom
housing, also forcing the nozzle housing
to rotate around its own axis because of
the gear system. This creates a criss-cross
cleaning pattern on the tank walls. When
the cleaning procedure is finalized the
valve is to be closed.
This manual has been prepared as a guide
for persons who will be operating and
maintaining the tank cleaning machine.
The key for long tank cleaning machine
life will always be carefully planned
maintenance, the tank cleaning machine
is actually doing a rough and dirty job for
you. With proper maintenance the Scanjet
SC 40RT will keep servicing you for many
years.

2. Safety Instructions
• If the machine is used in potentially explosive atmospheres then tapes or
joint sealing compounds, which are electrical insulators, must not be used
on threads or joints, unless an electrical connection is otherwise established
to ensure an effective grounding. In addition, connection pipe work must be
electrically conductive and grounded to the tank structure. The resistance
between the nozzle and the tank structure should not exceed 20 000
Ohm. This is important in order to avoid any build up of static electricity
in the machine. For further information see CENELEC R044-001 Safety of
Machinery, guidance and recommendations for the avoidance of hazards
due to static electricity.
• When the equipment is operating in potentially explosive atmospheres,
measures have to be taken to verify that the tank is inert at all times during
cleaning operation. This is to avoid sparks and possible explosions since fluids
moving at high velocities through air causes electrostatic build up in the
media. As an extra precaution the cleaning media could be made conductive.
• The machine should be installed in accordance with national regulations for
safety and other relevant regulations and standards.
• Precautions should be made to prevent starting of the tank cleaning
operation, while personnel are inside the tank or otherwise can be hit by
jets from the nozzle.
• In EU-countries the complete system have to comply with EU-machine
directive and should be CE-marked. In North America consult Underwriters
Laboratory for any specific regulatory needs relative to the entire CIP (Clean
In Place) System.
• Earmuffs should always be used when operating machine.
• Safety goggles should be used when opening cofferdam plug.
• Be careful not to drop tank cleaning machine/equipment when lifting and
carrying. Dropping the machine could cause serious injuries. Never stand
under the machine during mounting.
• When handling the tank cleaning machine, never lift machine by the nozzle.
• The equipment may only be used for tank cleaning operations as described
in this manual.
• The equipment has not been assessed as a safety related device as referred
to in directive 94/9EC Annex II, clause 1.5
Always follow these instructions before taking the SC 40RT into service!

3. General Description
Cleaning media comes from the supply line and enter through the inlet housing,
passing over a turbine which drives the drive unit via a magnetic coupling,
continue through the main pipe to the nozzle and then out in the tank.
The drive unit will rotate a shaft inside the machine, the
turning shaft. The turning shaft is connected to the bottom
housing that rotates the nozzles via a gear system. The
nozzles will hereby clean the tank in a criss-cross pattern.
The rotation speed is controlled by the rotation speed of
the turbine and could easily be set to desired speed, see
“7.7. Speed Adjustment” on page 20.
The rotations of the nozzles are indicated on the top nut
visible through the cofferdam or on the top shaft on top
of the drive unit.
The rotating nozzles will create a cleaning pattern as per
below on the vertical tank-walls. After one cycle a cleaning
pattern will be created as per fig 1. After four cycles the
pattern will be completed as per fig 2. After this the
pattern will be repeated.
A full pattern is created when the main body has rotated 47 turns. With a
rotation speed of 2 rpm will a full pattern take approx. 23,5 min. Note that the
time is depending on the actual setting of the turbine and water pressure. One
cycle will take about 6 minutes.
Cleaning of tanks is a process depending on a number of factors; the soilage of
the tank, distance to tank walls, cleaning procedure and cleaning agent. All these
factors are deciding for the number of cycles that needs to be run.
