1 General information

1.1 Function

The DUNOS O50 F - Ex and O90 F - Ex Target Jet Cleaners are orbital target jet cleaners.

They are driven by the cleaning medium. The machines are designed with little dead space

and are produced from certified materials in Germany. The surfaces and their roughness

are constantly monitored during production.

The cleaning medium, filtered according to the relevant regulations, is fed into the target jet

cleaner. The target jet cleaner is either placed directly on the tank flange or placed in the

tank via a support tube or lance. The connections are variable, standard connections are

described in the chapter on “Technical data”. The inflowing medium is fed to a turbine, which

generates an output speed of 10 to 14 min−1 with the downstream gearbox. The target jet

cleaner is driven via a drive shaft. Due to the design of the orbital driven target jet cleaner,

the outflowing jet of cleaning agent is applied to the container wall in the form of a horizontal

eight with high impact. Depending on the type of coating to be cleaned, a user-defined

amount of chemicals must be added to the cleaning medium.

Important: Onlypart of the cleaning medium passes through thegear unit. The main volume

flow is routed via a bypass to the target jet head with the nozzles. This minimises pressure

loss and ensures maximum volume flow for the nozzles.

The target jet cleaners can be operated with various nozzle diameters.

This enables the devices to be perfectly adapted to the cleaning task at hand.

1.2 Proper use

The target jet cleaners may only be operated in closed containers. Operation

outside of a container can lead to severe injury from the high impact of the

emerging liquid jets. The cleaning agent would additionally be widely dis-

persed into the environment.

Subject to technical modifications.

1.2.1 ATEX zone

In potentially explosive areas of zone 0, 1, 2 & 20, 21, 22, only appliances may be imple-

mented for the application purposes of the design and certified, authorised and designated

by ATEX.

The DO 50 F-Ex and DO 90 F-Ex target jet cleaners are designed for use in the ATEX zones

described and are therefore suitable for gas and dust environments.

The personnel for commissioning and inspection must be appropriately qualified for work in

hazardous areas. Furthermore, the operator must ensure that the contents of the operating

manual are fully understood by all persons involved in the installation, commissioning and

operation of the target jet cleaners described.

Conversions, as well as modifications, to the target jet cleaners are forbidden

and will always lead to the termination of ATEX approval.

Another or derived usage is not deemed to be approved usage and AquaDuna

GmbH & Co. KG is not liable for the arising damage.

The Ex target jet cleaners have been constructed according to the state of

the art and are safe to operate. From faulty operation or improper installation,

hazards to life and limb of persons can arise, to the EX target jet cleaners

themselves and to the operator’s equipment.

1.2.2 Component marking

EX target jet cleaners are marked as equipment according to:

II 1 G Ex h IIB T6…T4 Ga

II 1 D Ex h IIIC T85°C…T135°C Da

the marking is engraved on the Ex target jet cleaner.

The EU type examination certificate number is: TPS 19 ATEX 051981 0018 X

Subject to technical modifications.

1.2.3 Operating conditions

The following conditions must be observed in order to use the Ex target jet

cleaners in accordance with their intended purpose:

The prevention of ignition sources caused by the cleaning process is the responsibility

of the operator. (TRGS 727)

The Ex target jet cleaners must be integrated into the local equipotential bonding

system. All conductive parts must be earthed or connected to other conductive parts.

The leakage resistance must be lower than 106Ω.

After exchange of the Ex target jet cleaner or the mounting for the supporting pipe

(lance), the leakage resistance must be measured and a value of 106Ω must not be

exceeded.

The assembly instructions (point 4) must be observed!

When installing the Ex target jet cleaner inside a container, e.g. a tank, it should be

observed that the distance of the Ex target jet cleaner to the wall of the container or

fittings is sufficient, so that any contact may be excluded.

The cleaning agent, used for operating the Ex target jet cleaner, must attain at most

80% of its ignition temperature.

If the Ex target jet cleaner is operated in a dust explosive atmosphere, then a maximum

of 2/3 of the minimum ignition temperature of the dust cloud should ever be attained.

The minimum conductivity value of the cleaning agent must not be below 1000 pS/m.

The Ex target jet cleaner must not be powered by gas or steam, as otherwise a

hazardous electrostatic charge within the Ex target jet cleaner can potentially arise. In

order to exclude operation with gas also with the start-up of the pump, the shut-off

device should be situated directly before the Ex target jet cleaner. The piping volume

between the shut-off device and theEx target jet cleaner should be assmall as possible.

All piping should be ventilated.

The Ex target jet cleaner should be operated with a 500 µm prefilter.

The maximum permissible ambient temperature for the operation of the EX target jet

cleaners is 135°C.

The maximum permissible medium temperature is 97°C.

The operator is responsible for observance of the conditions.

3 Maintenance

Depending on the operating conditions, the Ex target jet cleaner must be

checked visually for external damage, rotation function and spray pattern at

regular intervals.

Maintenance of the EX target jet cleaner by the manufacturer is recommended after a max-

imum of 300 operating hours. Depending on the prevailing operating conditions, such as

operating pressure, temperature, properties of the medium or influence on the operator's

plant, it may be necessary to carry out maintenance at an earlier point in time.

Maintenance and installation of the Ex target jet cleaner can only be carried out at the man-

ufacturer's works, as defined safety welding seams must be applied after assembly.

The ATEX certification expires after dismantling of the Ex target jet cleaner by

the operator or third parties.

4 Installation and commissioning

4.1 Installation of Ex target jet cleaners

Observance of operating conditions (Point 1.2.3.) is to be ensured.

If the Ex target jet cleaners are mounted by the operator on a support tube

(lance), the interface between the customer support tube and the Ex target jet

cleaner must be fixed with a safety weld seam.

The securing seam must be applied in such a way that an O-ring inserted for sealing is not

damaged.

1. Screw on support tube 2. Weld interface

4.2 Assembly and operating personnel

The operator of the target jet cleaners is obliged to train the assembly and oper-

ating staff. All persons handling rotating and spraying machines must have been

instructed on the hazards connected with these machines.

Persons who are not registeredas operating staff should not linger within the operating area

of the machines. The operator must assure the necessary measures.

Subject to technical modifications.

4.3 Commissioning

Observance of operating conditions (Point 1.2.3.) is to be ensured.

If all pipelines or supply lines to the target jet cleaner are firmly connected and

the shut-off valves are closed, the target jet cleaner is prepared for initial com-

missioning.

The prefilter in the supplypiping to the target jet cleaner must be checked for proper function

and the filter body must be installed.

Before commissioning, the supply piping to the target jet cleaner is to be rinsed through.

Metallic impurities and welding residue may lead to damage to the target jet cleaner.

When the unit is put into operation for the first time, make sure that the supply line to the

target jet cleaner has been vented, especially in the case of long supply lines. This avoids

pressure shocks which could damage the target jet cleaner.

For hand-guided fittings, these are not to be opened abruptly in order to avoid pressure

shocks.

5 Integration into a plant

5.1 Automatic control

If the target jet cleaners are integrated into an automatically running facility, then it is to be

ensured that the target jet cleaner can be monitored during its functioning. This can be done

by means of rotation monitoring or a visual check. The function check is to be documented

during visual inspections.

5.2 Manual control

If the Ex target jet cleaners are to be controlled by hand-guided means, then it must be

observed that pressure shocks are avoided. The servicing elements are thus to be opened

and closed slowly. If steam is applied to the Ex target jet cleaner externally, it must be

ensured that the temperature does not exceed the specified limits. Monitoring of the target

jet cleaner must be ensured.

5.3 Emergency shutdown of the plant

To be able to bring about an emergency shutdown of the target jet cleaner, it is

essential that the operators of the facility are familiar with the facility’s design.

It is vital, that training in emergency shutdown be given and the necessary elements for

emergency shutdown be known. The training of those entrusted with cleaning is to be doc-

umented.

The manufacturer's liability for the consequences of incorrect plant operation is excluded.
