Arena Centro Skating Rink

The Centro Oberhausen shopping centre was built on the site of a former coalmine in the north-western part of the Ruhr industrial area. The modern complex includes an attractive multi-purpose event hall for an audience of 13,000, which YORK upgraded with an ice-skating rink.

Requirement

As the building needs to be used for a variety of events without lengthy conversion times, it called for a refrigeration system that would be able to reliably produce different consistencies of ice in the shortest possible time.

Solution

Refrigeration is achieved using two liquid chillers with screw compressors. Ammonia-cooled glycol water circulates in the pipe network within the concrete foundation slab. This ensures maximum safety, environmental compatibility, economy and availability. Special plate heat exchangers ensure that the facility is highly efficient while requiring a relatively small charge of ammonia.
