1.2 Selection of system
The great degree of flexibility, an important characteristic of the DELTABOOSTER, means that
each individual customer may select the system which suits his cleaning needs.
The following solutions are offered:
NUMBER OF PUMPS
Choose from 2 to 6 pumps depending on the capacity required at the same time. In other words,
the number of pumps should be decided on the basis of the number of places that are to use
the system at one and the same time.
LINE PRESSURE
The line pressure is the maximum working pressure for the individual user and is of importance
to the dimensioning of the pipeline, of course.
As a standard the system is adjusted to a line pressure of either 120 bar or 160 bar, but it may
be adjusted to a line pressure within the area 90 to 160 bar. This adjustment should only be
done by a specialized Nilfisk-ALTO customer engineer.
SELECTION OF SPRAY LANCE
For each of the line pressures (120 and 160 bar) there are nine different spray lances developed
especially for the
DELTABOOSTER. Each of the nine spray lances represents a combination
of pressure and water volume. Users may therefore always select the job-right combination of
pressure and water volume.
