Top snow quality is guaranteed with the adjustable TL4 manual snow lance thanks to an additional third nozzle on each of the three rings. The lance has four manual control settings and two possible nozzle configurations. Like the other lances, the TL4 manual lance also comes standard with ceramic nozzles and nucleators with ruby inserts. The best snow production is guaranteed across the entire operating range, even at limit temperatures and at low operating pressure.
Rapid assembly
Top-quality snow
Remarkable lance head
Thanks to the robust mechanical lance construction and the simple and stable plug-in connections, quick and uncomplicated assembly is possible.
Continuous top snow quality throughout the entire operating range is guaranteed thanks to nucleators with ruby inserts.
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 manual control settings.
The TL4 manual is built to impress with perfectly coordinated components: nozzles with ceramic inserts, an oil-free compressor (for the model without central air), the weldless filter, and nucleators with ruby inserts that guarantee an optimized mixture of air and water for snow that is consistently the best quality.
Technical 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 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.
The manual overground valve block is easy to operate and has 4 potential settings. The valve block is also available with an optional filter. Both versions can be equipped with an optional discharge heater.
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 water filter with seamless WEDGE WIRE filter insert made of nickel chromium steel guarantees fault-free operation, simple cleaning and long service life.
