The outstanding feature of the TechnoAlpin V series of snow lances is their round head with its optimized ratio of interior to exterior surface. A honeycomb-type system enables a special heat transfer system which keeps the lance head free of ice in conjunction with countersunk aluminum nozzles, even in adverse weather conditions.
The innovative development of the ceramic nozzles and nucleators provides the V3ee snow lance with an outstandingly low air consumption at maximum output. The energy consumption in comparison with the V3 snow lance and the same amount of snow is reduced by 50 %. It has four control settings and thus produces top quality snow, both at borderline temperatures and in low temperatures.
Manual and automatic versions of the V3ee lance are available. The overground valve block on the lance mast and the lightweight support with plug-in connectors greatly enhance the usability of both models.
The further development of nucleators and nozzles is the reason for the outstanding reduction in air consumption of the V3ee. The nucleation process is better with the new nucleators, and the ambient air is used more efficiently. The nozzles are refined to a high standard to guarantee optimized spray action.
All the nozzles are fitted with long-life ceramic inserts. A special heat transfer system keeps the lance head free of ice, even in very cold temperatures and with a prevailing headwind, without using additional energy.
The TechnoAlpin snow guns are fitted with an aluminum oil-free piston compressor with integrated cooling circuit. This system has been in use since 1999, allowing the snow guns to be positioned at any angle. The oil-free compressors made by Kaeser are also very environmentally friendly and ensure that no oil escapes into the environment through the snowmaking process. They operate at the same flow rate and yet they use less energy and do not need to be serviced annually. With no oil filters, trap cartridges, oil level monitors and stationary heating installations, this all adds up to a reduction in the annual running costs of a snowmaking system.
The air consumption of the V3ee snow lance is reduced by 50 % in comparison with the V3 lance and is therefore fitted with a smaller 2.4 kW compressor.
The automatic YB valve of pressure class PN100 regulates the water pressure, water flow and airflow for the lances. The opening and closing cycle includes water and air discharge. The valve has a patented closing mechanism which guarantees automatic closure in the event of a power failure.
One outstanding feature of the overground valve block is its excellent accessibility allowing rapid and simple cleaning of the filter and drains without having to climb down into the pit. Water and air can be connected easily without the risk of confusion, as the Camlock couplings are different sizes.
Up-to-date weather information is needed so that the snow gun parameters can be adjusted to the prevailing conditions for optimum performance. The current air temperature and relative humidity are therefore always measured and processed in the meteo station. It is also possible to install sensors to measure the wind direction, wind speed and snow height.
