Technical components

Integrated frequency drive


The inbuilt frequency drive allows rapid and simple conversion from day-time to night-time operation. The snow output can be increased during the day while snow-making operations at night can be carried out at a reduced speed and therefore at a lower volume.

The turbine is soundproofed and fitted with a perforated plate which absorbs the noise from the turbine. The motor is fitted with five special blades which produce a high air output with reduced noise levels.

Nozzle ring


All TechnoAlpin fan guns are fitted with hard-wearing Quadrijet nozzles with ceramic inserts. The ceramic inserts guarantee a high level of durability and resistance even when used with aggressive water. The four-jet technology is used to optimize and equalize the spray action and therefore to guarantee top snow quality. This technology has been proving its efficiency since 1992. The heating system in the nozzle ring operates selectively which results in reduced energy consumption.

Oil-free compressor


All the snow guns produced by TechnoAlpin since 1999 have been fitted with an aluminum oil-free piston compressor with integrated cooling circuit. The compressor in the Piano has special air filters to reduce noise level. A soundproof cover provides additional noise insulation. The snow guns can be positioned at any angle thanks to the oil-free compressor. The oil-free compressor supplied by Kaeser boasts excellent green credentials in guaranteeing that not one single drop of oil will leach into the environment. An oil-free piston compressor also consumes less energy at the same rate of air flow. Oil-free compressors do not require an annual service. With no oil filters, trap cartridges, oil level monitors and stationary heating installations, this all adds up to a reduction in annual running costs.

Valve technology & water filter


Nozzles can cut in and out on all TechnoAlpin fan guns depending on the temperature. This keeps the snow quality consistently high. This regulation can be a simple and infinitely variable process thanks to the valve block. The seamless water filter insert is a WEDGE WIRE-type filter made of high-quality nickel chromium steel and is integrated in the valve block to save space. The fact that it has no weld seams makes it extremely durable.

Up-to-date weather information is needed so that the snow gun parameters can be adjusted to the prevailing conditions for optimum performance. The data collected in the meteostation therefore always include the current air temperature and relative atmospheric humidity as a minimum. It is also possible to install sensors to measure the wind direction, wind speed and snow height.
