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: Only part of the cleaning medium passes through the gear 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.
