Technics have always played a leading role for CORTECH, this is specially prooved by the several patents registered over the years. On this ground, CORTECH can be defined a real R&D laboratory besides a company. This technical leadership allowed CORTECH to bring out over the years some products that represented a real revolution in snow making. Letís make some examples:
An important know how that CORTECH has fully included in its new products:
The Snow/Water transformation ratio is 2,3, meaning a snow density of 435 kg/m3. This kind of snow can be easily worked with a snowgroomer yet very resistant to the wear caused by ski. A ratio below 2.05 can cause the release of water over the slopes. The snow made for maintenance can have a ratio of 2,5.
The snow thickness depends on the slope. The relation we use is: Snow thickness [cm] = Slope [%], with a minimum value set to 15 cm.
For slopes exposed to the sun or with a rough and stony ground, this value is incresed by 50%.
During the winter season thereís the need to restore the snow thickness depending on the meteorological conditions. Without precipitations this amount of snow can be estimated at nearly twice the theoretic volume needed for the first covering. The total amount of snow will hence be three times the first need.
