1. Introduction

The Scanjet BIO 25 is a highly versatile machine for use in hygienic applications as

well as other industrial applications. Its unique design makes it easy to install, use

and maintain as well as reduces the pressure drop through the machine.

The BIO 25 is per standard delivered with two or four nozzles in different nozzle

sizes, between Ø5mm and Ø18mm.

A special nozzle conﬁguration with two extra nozzles cleaning the outside of the

machine provides unmatched self cleaning capability.

This manual has been prepared as a guide for persons who will be operating and

maintaining the tank cleaning machine. The key for long machine life will always

be carefully planned maintenance. If this is properly executed the Scanjet BIO 25

till keep servicing you for 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 by the jets.

• 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.

• Ear protection should always be used when operating machine.

• Be careful not to drop the tank cleaning machine/equipment when lifting

and/or carrying. Dropping the machine could cause serious injuries. Never

stand underneath the machine during mounting or operation.

• 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 BIO 25 into service!

3. General Description

The Scanjet Bio 25 is a media driven and lubricated tank cleaning machine. No

lubrication substances such as oil, grease etc. are used. All materials in contact

with the machine meet the general standards for hygienic process. Ceramic

and tungsten bearings are standard for an extra long service life. The unique

design of the Scanjet BIO 25 makes it completely self-cleaning and self-cleaning.

There are no interior pockets where water and dirt can accumulate, making this

machine one of the best choices for hygenic applications.

Functional Principle

When cleaning media enters the machine it ﬁrst passes through a turbine and a

worm gearbox, then a nozzle housing leading it out through the nozzles and into

the tank. The turbines rotation drives the worm gearbox, making the machine

rotate around its own axle and at the same time, the nozzle housing is forced to

rotate clockwise.

A combined motion of the machines body and nozzle housing creates a criss-

cross cleaning pattern inside the tank. After 6 1/8 rotation of the nozzle housing,

a ﬁrst course pattern has been created. This process is repeated 8 times, each

time indexed from each other until a full cleaning pattern has been created.

When this is ﬁnalized, after 47 rotations of the machine body, or 49 rotations of

the nozzle housing, the ﬁrst cycle will be repeated.

Cleaning of tanks is a process depending on a number of factors; soilage, distance

between nozzles and tank walls, cleaning media, temperature etc. All of these

factors need to be considered before a proper cleaning can be accomplished.

The rotation speed of the machine idepends on ﬂow rate through the machine.

Higher ﬂow rate makes the turbine spin faster and because of this the machine is

equipped with different turbines according to nozzle size and intended operating

parameters.

5. Performance Data

Under performance data Scanjet presents Effective Jet Length.

Effective Jet Length is deﬁned as the distance between the nozzle and the tank

surface where the jet achieves 250 mm water column (50lbs/sqr.ft) impact force

at tank surface. The Effective Jet Length is measured at horizontal and static

conditions.

The Jet Length is affected by a lot of different factors such as rotation speed of

the machine (velocity of the jet at the tank surface), temperature of the cleaning

media, cleaning agent used and so on.

The vertical jet length can be estimated to be approximately 1/3 less than the

horizontal jet length.

The following graphs show the ﬂow, effective jet length (radius) and complete

cleaning time for each combination of inlet pressure and nozzle diameter. Other

nozzle diameters and maximum jet lengths are available upon request.

Please note that when equipped with non-return check valve, the ﬂow will

decrease an estimated 10%.

Flow vs Pressure

The inlet pressure has been measured at the machine inlet. In order to achieve

the same performance as indicated in these curves the pressure drop in the

supply line must be taken into consideration.
