7. Supply with water (open the hydrant slowly)
8. Regulate the water flow rate. By the position of the magnetic valves and the
incoming pressure, the water flow rate is adjusted to the value accommodated
to the environmental conditions.
Water pressure minimum 8 bar
Water pressure maximum 40 bar
2.5. Changing the water flow rate:
The water flow rate must be adjusted according to the climatic conditions. Since
the adjustment of the water flow rate depends on a host of parameters, it is difficult
to specify generally applicable data with respect to the switching points between
the individual stages.
Some of the factors influencing the possible water flow rate are:
• Air temperature and relative air humidity
• Ground temperature (snow temperature)
• Water temperature and water quality
• Wind
• Incline of piste and setting angle of the machine
• Desired snow quality (specific gravity)
The water flow rate is adjusted by 2 means of control.
• Electric On-Off valves, switching the nozzle rows on and off
• Water pressure 8 bar - 40 bar
The nozzle ring is equipped with 4 rings of nozzles, with the Nucleators (N - outer)
always on. The rings with the water nozzles ring 1 – ring 4 are either fixed open
(ring 2 for Eco) or switchable with magnet valves.
With the switches 1.R / 2.R / 3.R / 4.R on the electric control box the magnet valves
fort he according nozzle rings are actuated.
