Nozzle Diameter and Blast Pattern
The nozzle selection should be based on finding
the best combination of air consumption, dry ice
consumption and cleaning efficiency.
the selection of the nozzle spread angle should
depend on how strong or weak a cleaning effect is
desired for a given dry ice consumption.
Small Blast Pattern
a small blast pattern gives a concentrated jet with a
high cleaning effect on a small area.
Wide Blast Pattern
A large spread angle, e.g. the flat nozzle, results in
a jet which for the same consumption of dry ice and
air cleans a larger area with a lesser cleaning effect.
Nozzle Size
it is most important to select the size of nozzle
which will provide the desired air velocity using
the available compressor capacity. choosing the
right nozzle size and type will optimize not only the
cleaning effect, but also the dry ice consumption
and the time required for the cleaning process itself.
refer to the air consumption table for guidance on
the nozzle selection.
air Consumption Table
the air consumption table indicates the air con-
sumption in relation to nozzle size and blasting
pressure. the maximum supply pressure of Kg50
and Kg30 amounts to 16 bar/232 psi.
example of Use of the Table
the air consumption table outlines the air consump-
tion achieved with the nozzle sizes available. if for
example a size 8 nozzle is used at a blasting pres-
sure of 6 bar (87 psi) the air consumption amounts
to 4.2 nm
3
/min (148.3 ft
3
/min).
the available compressor capacity will always need
to be taken into consideration and therefore it may
be necessary to do some test blasts and observe
the results until the optimum combination of nozzle
size and blasting pressure for a certain application
is found.
