Superior technology and innovative functionality

The TR8 fan gun boasts unparalleled innovative improvements combined with proven technologies from TechnoAlpin.

New technology with just one motor

For the first time on a snow gun, the propeller and compressor are driven by just one electric motor. The rotary vane compressor is oil-free, delivers a more uniform compressed air flow, weighs less and is easier to service.

Maximum reliability and unparalleled efficiency level

Thanks to its permanent-magnet motor with inverter, the TR8 achieves IE4 energy efficiency. At the same load current as the previous model T40, but with significantly increased airflow, the TR8 can be operated across a very wide voltage range. The motor always works at its maximum efficiency.

Very smooth running and insensitivity to vibrations

The proven low rotational speed, which is already used in other machines from TechnoAlpin, is also found in the TR8 turbine concept. Because it turns at just 1,780 rpm and has its turbine motor inside the machine, the TR8 impresses due to its smooth running, low noise emissions and resistance to vibrations. The noise level of the machine has been reduced, and the audio frequency has also been adapted. The working environment of the snowmaking crew is significantly improved and the TR8 is also suitable for use in the vicinity of urban areas.

Optimally tempered compressed air

The air is always efficiently cooled thanks to compressed-air cooling in the water circuit of the valve block. This eliminates the need to switch the cooling on and off and ensures a relatively constant water temperature. It also ensures the compressed air is adequately cooled at marginal temperatures, but hardly increases the cooling of the compressed air at lower temperatures. The cooling thus remains more or less constant within each temperature range.

Easy to use and service

Its low dimensions and light weight make the TR8 very stable and easy to use, while also making it more service-friendly. Servicing the snow gun is revolutionized by a new side panel that opens upward. All main components can be accessed in a few seconds – and are at eye level. The front ring can also be removed using a couple of handles.

Integrated design

Weather station, LED work lights and LED warning lights are integrated into the fold-up turbine housing. This gives the TR8 a streamlined look, making servicing a breeze at the same time. There are no protruding parts, greatly reducing the problem of snow deposits.

Infinitely variable nozzle adjustment

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

Unique ceramic nozzles with four-jet technology

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. TechnoAlpin has been using this advanced technology since 1992 and the heating system in the nozzle ring operates selectively, resulting in reduced energy consumption.
