NOZZLE SELECTION AND AIR CONSUMPTION
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 to 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 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.
Air Consumption Table
The air consumption table indicates the air consumption in relation to nozzle size and
blasting pressure. The maximum supply pressure of the Xcel 6 amounts to 10 bar/145
psi.
Example of Use of the Table
The air consumption table outlines the air consumption achieved with the nozzle sizes
available. If for example a size 8 nozzle is used at a blasting pressure of 6 bar (87 psi)
the air consumption amounts to 4.2 Nm3/min (148.3 ft3/min)
.
The available compressor
capacity will always need to be taken into consideration and therefore it may be
