The Mars Lakeview Arena in Duluth, Minnesota, is a privately owned and operated ice skating arena that operates year-round. It services 120,000 patrons a year, including college and high school hockey teams, the Duluth figure skating club, and the general public.
The rink had been supporting a full-size ice sheet with its original 1999 flooded chiller system, charged with 1,750 pounds of R-22. Although the system ran for some time without needing to have refrigerant added, potential for a leak in the future required that more R-22 be added to the system. This could get costly, given the pending phaseout of R-22. So the arena partnered with SCR and The Chemours Co. to discuss a retrofit.
