Snowguns

Why do new Low Energy Snowguns freeze up in the air lines?

There are a few operating factors that will cause freezing in the air lines. If you have too much moisture in your compressed air, it will come in contact with the cold metal and will start to freeze. It will continually build up more ice on the inside until the air line is completely closed off. If the problem gets to this point, you will need to take down the snowgun and thaw it out.

What can I do to stop the nozzles and snowgun heads from collecting ice?

Most Low Energy Snowguns do not use very much CFM of air so they are subject to the wind. Keep your tower snowgun facing away from the prevailing winds. However, you can use most of the HKD snowguns with a side wind without too many problems.

If the snowgun heads collect ice or nozzles start to freeze, how can I thaw them out without taking down them down?

You can lower the snowgun and use a small handheld torch to heat the nozzles and head. However, do not put too much heat on them as there are rubber gaskets and o-rings in the heads that will be affected. You can also use your hands to warm up the nozzles.

Is there any maintenance work that should be done in the off-season on the snowguns?

Yes… each year every snowgun should be looked at for any damage that may have been caused when the snowgun froze or when the snowgun head or nozzles were overheated. The snowgun head on Valved snowguns should be removed from their towers, taken apart, and the o-rings and gaskets replaced if required.

Common Concerns (Misconceptions) about Surfactants and DRIFT®...

• They make small particles
• They make fogs
• They enhance evaporation
• Toxic to fish

The data and experience show otherwise...

Spraying Systems Co. Test Number 22T92+1
No significant change in drop size
      No increase in smaller drops
No significant change in drop pattern
       No chance of enhancing fog

Therefore, no enhancement of evaporation

Mountains specifically looking at effect on evaporation
No observable change in plume height during medium temperatures (20’s)       - does go further
In cold temps – plume was higher – until turned up water or turned down air
      - positive operating effect.

Therefore, no enhancement of evaporation

Environmental Studies - DRIFT
LC50 – 115 to >1,000 ppm
      Use rate is 3 ppm
      Degrades by hydrolysis – dissociates in water over several days

Therefore, DRIFT poses no danger to fish and other aquatic organisms when used according to directions – and no environmental residual
