TechnoAlpin Nucleators

I’ve always thought, the air/water mix is determined at the gun’s ground level connections. The mix then goes up the shaft to the head. TA below speaks of determining mixture at the head. How do fixed holes accomplish such?

TechnoAlpin: Snow production with gemstone quality

The improvement of existing products and the development of new solutions are essential focal points at the core of TechnoAlpin. Only in this way can snowmaking systems be continuously optimized. The latest innovation from TechnoAlpin is hidden inside the V3 and V3ee snow lances. It is an extravagant detail with impressive overall results. A machine-generated ruby insert in the nucleators ensures that they are supplied with the correct amount of water for the air and water mixture and therefore guarantees the best snow quality over many years.

The nucleators are used to generate a mixture of water and compressed air in snow guns which produces so-called nuclides by expansion into the atmosphere and is therefore an essential component of the snow production process. Each nucleator has a hole which allows the correct amount of water into the compressed air. This opening has now been reinforced with a ruby insert on the lances in the V3 series. The ruby guarantees maximum wear resistance even in aggressive water, e.g. with glacier shale and at high operating pressures.

This revolutionary nucleator guarantees the optimum air and water mixture and enables the lances in the V3 range to produce snow of consistently top quality over many years, as the hard-wearing ruby inserts significantly reduce the need to replace the nucleators.

The snow lances in the V3 series boast impressive energy efficiency and feature a round head with an optimized ratio of interior to exterior surface. There is a special rib system inside the head, allowing the energy of the water to be used and the heat generated by friction to be transferred from the inner surface of the head to the outer surface. The sunken nozzles in the head also play a part in keeping the head free of ice, even in extreme weather conditions. The outstanding feature of the V3ee lance over and above this is its extremely low air consumption at maximum output.

The new nucleators with ruby insert will already be installed in all V3 and V3ee lances as standard in 2018. It is also possible to order the new nucleators from the spare parts store and insert them into the lance models in the V range.

    The nozzle orifice needs to remain a consistent size to have a consistent mix over time. What happens with nozzles is the orifice wears over time and becomes enlarged, which results in larger droplet size and makes wetter snow with reduced production.

    Typically, resorts will replace nozzles as the orifices become worn. Resorts that don't replace nozzles will see increased snowmaking cost over time with less production and lower snow quality.

    The new ruby insert nozzles are designed to last longer, which effectively results in improved consistency over time.

    I wonder what a diamond nozzle could do ;)

    Industrial diamonds are pretty cheap actually.
  • Ok, I didn't understand, the article was simply talking about keeping consistent flow by preventing wear, not adjusting the mixture.
  • SMI has come out with a similar concept for it's Polecats, ceramic lined nozzles. They cost more than conventional nozzles of course.

    If you change the flow (by wear) you're adjusting the mixture unintentionally.
  • Geezum-- a long way from the locally made snow guns I remember from my youth. Should've taken pictures of them back then.

    The air water mix is always accomplished at the tip of the gun, either externally (water spraying out of a nozzle with a separate nozzle for air intercepting and dispursing the spray from the water nozzle) or internally (air forcing water through a nozzle). In either case it’s the force of the air combing with the force of the water to shred the water particle to a small enough size to freeze properly.

    This is standard practice on all snow guns, whether it’s an older air water gun like a Ratnik or a new gun such as a HKD or Snowlogic. Ceramic tips certainly cut down on wear, however are 3 times the cost. SMI nozzles have to be replaced about every 3 years where as I have never replaced nozzles on a TA gun.
