Sullivan Arena is second rink in the nation to use a CO2-based refrigeration system to generate its ice
ANCHORAGE, Alaska — The Alaska Aces, a professional hockey team in Anchorage, Alaska, and winner of three league-championship Kelly Cups, is skating on “greener” ice this season. It’s not the color of the ice that’s changed, but the effect it has on the environment and its money savings.
The team’s Sullivan Arena is the second rink in the nation to use a carbon dioxide (CO2)-based refrigeration system to generate its ice. The Advansor CO2 Booster System from Hillphoenix uses refrigerant that does not contribute to global warming. CO2 refrigerant has a global warming potential (GWP) rating of 1. By comparison, a traditional hydrofluorocarbon-based system can have a GWP rating as high as 3,985.
