Part of the new TechnoAlpin TL lance series, the TL4 automatic snow lance is impressive, with precise control and maximum efficiency across the entire temperature curve. It has an additional third nozzle on each of its three rings. The nozzle rings open and close using the Smart Distributor, which works like a valve block. Consequently, the lance has four different control settings to optimize regulation of the water flow and provide the best snowmaking performance in the marginal temperature range and at lower temperatures as well. All TL lance heads are mounted on the lightweight universal tube, recently developed by TechnoAlpin.
New lance head
Unparalleled snow quality
Uncomplicated assembly
The new lance head is highly energy and resource efficient thanks to three nucleators with ruby inserts, three rings, each with three ceramic nozzles, and four control settings.
Thanks to the nucleators with ruby inserts, consistent, optimal snow quality is guaranteed, especially at limit temperatures or even at low operating pressure.
Simple, fast assembly is possible thanks to stable plug-in connections and a robust mechanical lance design.
Like the other lances in the family, the TL4 also features high-quality equipment, such as nozzles with ceramic inserts, an oil-free compressor (for the model without central air), the weldless filter and nucleators with ruby inserts. They are built to impress, with controlled air consumption and an optimized mixture of air and water, regardless of the water pressure.
Tech. Components
The shape of the head makes the TL lances less susceptible to wind and frost and allows snowmaking on narrow and wide slopes while keeping noise emissions low. This is a huge advantage on slopes near residential areas. The ceramic inserts of the wear-resistant nozzles also guarantee consistently high snow quality season after season. The standard version of the lance is also joined by a model for warm climates so as to cater for varying local weather conditions.
The robust mechanical structure is made of hot-dip galvanized steel to guarantee added stability and has plug-in connections for easy installation. The height of the lance is adjusted by means of the hydraulic lifting cylinder. The electric switchboard is compact and easy to access.
The water filter with seamless WEDGE WIRE filter insert made of nickel chromium steel guarantees fault-free operation, simple cleaning and long service life.
The simple and sturdy plug-in connection of the mechanical structure makes it quick and efficient to fit on initial installation and just as easy to dismantle. The plug-in base has a double hole pattern and a flat base, and is therefore suitable for various pit and concrete foundations.
The automatic YB valve of pressure class PN100 regulates the snow lance water pressure, water throughput and airflow. 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.
Small Trail version
The TL4 is also available in the ST (small trail) version. It also has three nucleators with ruby inserts and four control settings. However, compared to the conventional model, it only has two nozzles per ring. Because of its especially narrow spray pattern, the TL4 ST is suitable for areas where snow has to be spread in narrow places, such as very narrow sections of slope or toboggan runs.

Versions
The central air model is mainly used on relatively low slope sections with air and water supply as well as a data cable.
The local compressor model is used on relatively low slope sections with water and electricity supply as well as a data cable. This model has an oil-free piston compressor with an output of 4.0 kW.
