The Ritchie Center will replace its 12-year-old ice rink chiller this summer with a $900,000 more efficient one. The new chiller will save the university approximately $40,000 in annual operating costs, according to Allan Wilson, director of Facilities Services at the Ritchie Center.
The ice rink currently uses a cooling component called glycol, which must reach zero degrees Fahrenheit to chill the ice rink to its typical temperature of 11-16 degrees, according to Wilson.
The current machine lasted 12 years, and he predicts the new chiller will last about the same. According to him, the last chiller ran 24 hours a day, seven days a week.
“You would hope that a machine like that would last longer than 12 years,” said Wilson. “But we have to remember that it was running all the time. It actually did pretty well.”
The new chiller will be built next to the existing plant.
“We’ll keep it so there will be redundancy in the future,” said Wilson. “If one machine breaks down, then we would always be able to produce a hockey game” [read entire article].
