Werner-Rittberger-Arena in Krefeld

Advert by IAKS member AST Eis- und Solartechnik GmbH

Before the 2016/2017 ice season, an inspection of the equipment of the Werner-Rittberger-Arena revealed problems with the ammonia cooling pipes in the concrete. As a result, operation of the ice rink’s old system had to be stopped.

The renovation approach of AST, which won the international tender from the city of Krefeld, proved to be the most economically attractive and energy-efficient solution. The temporary AST EPDM classic ice rink was installed on the existing concrete floor together with the brand-new, energy-reducing AST ProSport Dynamic boarding system. Costly and time-consuming reconstruction or preparation work in the hall was not necessary.

The technology required for cooling is housed in a separate system outside the hall building. The refrigerant is supplied by a highly efficient refrigeration machine, which is installed on a mobile tubular frame, runs very quietly and is also enclosed in sound insulation.

The glycol-water mixture is fed into the EPDM mats via pipes and supplies the entire ice surface with energy-optimised cooling. The system has a modular structure and can, if necessary, be dismantled and reassembled at a different location.

The AST ProSport Dynamic ice hockey boards with acrylic spectator protection, and the player and penalty benches naturally comply with the current rules of the International Ice Hockey Federation (IIHF).
