A large sports and recreational facility to be used for international ice hockey, speed skating and figure skating competitions was built in Nishnij Nowgorod, Russia. It also serves as a playing field for the Russian ice sport "Bandy." To this end, Axima Refrigeration built one of the world's biggest skating rink, with a surface area of 12,600 square meters.
Requirements
The construction of the ice-skating rink required extensive technical and logistical know-how, along with special experience with major international projects.
