From the FAQ:
Q: How does it stay cold in Ski Dubai?
A: Our facility is specially designed as a massive cold box. The walls have numerous levels of insulation and the roof is 5 metres higher than the ceiling, providing very efficient insulation. This makes Ski Dubai one of the best refrigerators in the world! We have 23 blast coolers (air conditioner type machines) that chill the air and maintain a temperature of -1c during operating hours. There are also kilometres of glycol tubing running through the floor (similar to the back of your refrigerator) that chill the snow, keeping the base of the snow solid, 30 tonnes of fresh snow is made daily.
You want an Alpine Ski vacation? NO WAY! True SKI Nuts (ummm yeah) say the snow pack on Ski Dubai is better than the Alps, due to humidity and temperature controls amd method, the snow is *PERFECTLY MADE*!
They use "hyper cooled" water and inject miniscule ice Crystal in the air at the same time the water is misted into the air. Causing full fledged snow flakes.
