Internal mixing guns

Internal mixing guns have a chamber where the water and air get mixed together and violently forced out an opening or through holes and fall to the ground as snow.

These guns are typically low to the ground on a frame or tripod and require a lot of air to compensate for the short hang time of the water. Some newer guns are built in a tower form and use much less air because of the increased hang time. The amount of water flow determines the type of snow that is to be made and is controlled by an adjustable water hydrant.

An internal mix system is an air/water system that mixes compressed air and water in an internal chamber in the snow gun nozzle. When this mixture exits the nozzle, it expands and supercools (cools to below 32°F). Tiny water droplets freeze into ice crystals that become nucleation sites that nucleate larger unfrozen droplets, and snowflakes form

[edit] Advantages / Disadvantages

  • Advantages: Less affected by wind; allows high wet bulb temperature; light and portable unit; covers wide trails; ability to adjust snow consistency
  • Disadvantages: Inefficient due to its reliance on compressed air and noise generated by air compressors
