Our products are present in plants of artificial snow and guns for artificial snow on ski slopes, for several years with considerable success. The snow guns have the characteristic of producing artificial snow from water from river or lake, mid and high pressure pump (form 10 to 40 bar). Every snow gun normally has 280-330 spray nozzles.
The main feature of these nozzles is to ensure a drop middle / fine, for better crystallization (processing water / ice) with free passage not too small to avoid clogging due to dirt. For this last reason, so to avoid clogging, it is important that the filtration degree placed before the snow gun is less than free passage of water of nozzle.
Normally spray nozzles used are hydraulic sprayers MX, MZ, steel, ensuring both the drop medium / fine and duration over time, even if they work at high pressures. There is also a specific template “MN” with sharp tip of the spray, to prevent the buildup of ice and make it much easier removal of any signs of ice. The adoption of an o-ring together with the BSP ensure proper sealing against leakage with the risk of ice formation.
MN nozzle, available in many variations of flow, also has a unique internal vortex that makes it very easy for the eventual removal of maintenance. With a screwdriver you can remove the part made in one piece.
This, considering the climatic conditions in which they operate and often the operator is wearing gloves of considerable thickness, is a big advantage over what is normally offered by our competition.
The fed of these nozzles installed on the snow guns are usually supplied by water drawn from reservoirs.
Filters for artificial snow plants
They are usually installed in pumping stations.
Normally there are high-pressure pumping systems that take water from lakes or rivers, send to reservoirs placed at high altitude, at or above the spray guns. From there, the water is handled by dropping or with low pressure pumps
Our filters are normally placed after the booster pumps (pressure less than 10 bar), before the high-pressure pumps, so that they can protect them.
The filters have the task of stopping all the ‘foreign’ parties (stones, branches, leaves, etc…) caught from the lakes or rivers.
The self-cleaning models allow avoiding downtime due to clogging filters in addition to having the benefit of being able to operate independently. This is because they are equipped with differential pressure gauge for pressure control inlet and outlet, a cleaning system that activates automatically when needed, and an automatic valve that, in places where there is no compressed air, can be electric.
In some applications have built filters to pressures of about 30 bar (after high-pressure pumps). The recommended filtration degree are between 100 and 500 microns.
