Technical components

Nozzle ring


With 24 Quadrijet type nozzles and eight nucleators, the TF10 Piano is one of the most powerful snomakers on the market. 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.

Valve technology & water filter

Nozzles can cut in and out on all TechnoAlpin snowmakers 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.

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 snow guns can be positioned at any angle thanks to this system. 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.

The oil-free compressor of the TF10 Piano also has special air filters and a sealed soundproof cover which provides additional noise insulation.



The turbine with internal motor running at 1,460 rpm (1,170 rpm at partial load) makes the machine insensitive to vibrations and significantly reduces noise emissions. Sound insulation cladding on the TF10 Piano also absorbs the noise of the turbine rotating.


With a turbine diameter of 90 cm, the TF10 and TF10 Piano outperform all previous TechnoAlpin fan guns. With a fan output of 18.5 kW and 4 kW of compressor power, they boast excellent energy specifications.

Frequency inverter


The TF10 Piano can be operated at partial load thanks to a frequency inverter integrated in the electric cabinet. The motor speed is reduced in this case from 1,460 rpm to 1,170 rpm. Snow production can therefore be guaranteed in noise-sensitive areas.



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.

Robust electronics


The electrical equipment of TechnoAlpin snowmakers complies with the applicable requirements in the relevant countries. The function and service life of some components can be adversely affected by frost therefore all such components are heated. The menu-driven control panel on the TF10 Piano has an illuminated, multi-line display which presents readings and information clearly. The electronic control unit ensures failure-free operation and optimum regulation.
