One basic success factor in snowmaking is the water temperature. A rule of thumb says that with increased water temperature, commencing of snowmaking in marginal temperatures increases accordingly. It is therefore critical that the water used has a maximum temperature of 1 - 2° C. To guarantee such ideal conditions, cooling towers are used.
For our systems, we are using GT model cooling towers made of thick sheet metal and steel profiles, which are connected by uninterrupted welded seams.
The cooling towers are designed as suction-ventilated counter-current flow machines, i.e. the fans are arranged in suction orientation, which reduces operating expenses.
The axial ventilator on the top of the cooling tower has a favourable fluidic profile. The motor is mounted directly to the ventilator, thus eliminating tedious maintenance. The ventilators are by default equipped with protection against icing over(thermostat).
