The TF10 Manual is an excellent combination of proven TF10 components and a completely new approach to manual snow-making processes, and it is impressive in terms of efficiency and usability.
All the fan gun functions can be operated with a control panel complete with display. There are 16 control settings to adjust the projection range and area coverage so as to enable tip-top snow even in changeable external conditions. Not only is consistent snow quality guaranteed as a result but slope preparation is also facilitated.
The most impressive feature of the TF10 Manual is the revolutionary manual control of the nozzles. This is no longer on the nozzle ring or on the valve block but instead the individual nozzles can simply be cut in or out on the display as required. It is therefore possible to have a fan gun in mobile use but also to mount fan guns on lifts, arm and towers without complex operating input. If fitted with an optional E-Motor, the TF10 Manual cuts out automatically in the event of a fault, thereby preventing damage to the machine and formation of ice on the slope.
As with the fully automatic TF10, the turbine motor on the TF10 Manual is located inside, making it insensitive to vibrations and therefore significantly reducing the noise emissions. This fan gun is therefore also suitable for use on slopes in residential areas.
With 24 Quadrijet-type nozzles and eight nucleators, the TF10 manual is one of the most powerful machines on the market. 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.
Nozzles can turned on and off 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.
The snow guns produced by TechnoAlpin are fitted with an aluminum oil-free piston compressor with integrated cooling circuit. This system has been in use since 1999, allowing the snow guns to be positioned at any angle. The oil-free compressors made by Kaeser are also very environmentally friendly and ensure that no oil escapes into the environment through the snow production process. They operate at the same flow rate and yet they use less energy and do not need to be serviced annually. With no oil filters, trap cartridges, oil level monitors and stationary heating installations, this all adds up to a reduction in the annual running costs of a snowmaking system.
A turbine with internal motor running at 1.460 rpm makes the machine insensitive to vibrations and significantly reduces the sound emissions. With a turbine diameter of 90 cm, the TF10 Manual outperforms all previous TechnoAlpin fan guns, boasting excellent energy consumption levels at 18.5 kW fan output and 4 kW compressor power.
Up-to-date weather information is needed so that the snow gun parameters can be adjusted to the prevailing conditions for optimum performance. The current air temperature and relative humidity are therefore always measured and processed in the meteo station. It is also possible to install sensors to measure the wind direction, wind speed and snow height.
The maneuverability and balance of the snow gun are optimized. The main units, such as the motor, compressor, electric switchboard and valve block, are cleverly arranged around the center line, and the center of gravity has been lowered, therefore despite its size the machine is only slightly heavier than other fan guns.
The stand and the optional two-part undercarriage allow a simple conversion of mobile units to a fixed lift-mounted installation. The front section of the undercarriage can be removed from the snowcat blade with a few hand movements and the machine can be linked up and attached directly to the lift carriage. The jacks and rear section of the undercarriage can then be dismantled.
Fixed tower-mounted snow gun installations are typically used for slope sections which are difficult to access and require large amounts of snow. The elevated position of the snow gun improves the snow output. The tower consists of a steel column which is 1.6 m high, and the mounting base has a height of 20 cm. The installation process is simplified by the low weight. Covering mats also come as standard, as does a service platform.
In the case of lift-mounted installations, the snow gun is mounted on a steel column which is 3.5 m or 4.5 m high and has lifting platform. This has a centering device to ease initial installation or to enable air installations. The snow gun is operated by Bluetooth remote control or from the ground by means of an optionally available keyboard at ground level. Lifts are available in manual design, with HIT-TRAC 8 or with hydraulic systems. Maintenance work can be carried out with the aid of various systems. Snow guns mounted on manual lifts can be lowered by means of a jack-hoist mechanism. The HIT-TRAC 8 lift can be operated with the HIT-TRAC 8 motor-driven rope pulling machine. The rope runs through the pulley assembly at the top of the lift and a return pulley on the carriage, thereby raising and lowering the snow gun complete with carriage. With the hydraulic lift, the snow gun is raised or lowered using an electric pump and hydraulic cylinder inside the lift column.
Snow guns can be mounted on a support arm measuring 12 m in length. This arrangement is typically used on wide sections which receive very little snow and where wind conditions require that the snow gun will need to be located well into the slope layout. The snow guns are operated by Bluetooth remote control or by means of an additional keyboard at ground level.
