“We’ll use the winter months to put the base in,” Klingenberg explained. “Then we need small sprays daily or weekly to maintain perfect conditions throughout the summer.” Heat generated by the cooling systems will be recovered for use in local buildings via a district-heating network. Rune Lorenzen, chairman of Røa Langrenn, a sports club near Oslo that offers cross-country skiing on the hills surrounding the capital, is following the development of the SNØ arena with interest. This year, Røa had to produce over 10,000 m³ of snow for its own activities. The outdoor arena hosts 600 young people who are members of the club. It is also open to the public.
Natural snow can weigh between 50 and 125 kg per m³, depending on how wet it is. Manufactured snow is between 2.5 and 10 times as dense as natural snow, and this makes it resistant to mild temperatures and wear, Lorenzen explained. There are also differences in snow made for indoor and outdoor uses, with the former process taking humidity into account. “Indoors, you have to add more air and use less water,” he said Lorenzen. “And that means you can’t make as [much] at a time compared to outdoors.” One major advantage of an indoor environment, however, is its constancy. “After the snow is first laid down, it will last a long time – we’re talking months,” he said.

Carrier's CO2 system meets our need for a long-term, cost-effective solution for Norway’s first indoor ski arena that will allow visitors of all ages to enjoy winter year-round. – Ing. Petter Nome, Ipnas
