Drift benefits
snowmakers in two ways. First, it breaks down the
natural cohesive tendencies of water, releasing the inherent surface
tension and heat. This allows water to form and flow as a mass
of flatter/thinner droplets each having a greater surface area. As
a result, these droplets freeze more rapidly and thoroughly as they
are blown into the cold air - allowing more particles to form in
the air and fall on the slope. Drift can improve
water flow by 3-5% - a 1-2 degree F gain in wet bulb
temperature.
Secondly, because of the
effect that Drift has on water, a
higher
ratio of water to air can be used - reducing energy costs and
increasing snow
volumes - thus increasing your mountain's profitability.
