With 57 ice sheets in operation year-round, Canlan Ice Sports was spending too much money on the electrical energy needed to keep rinks cool at the company’s six-rink York location in Toronto. Management realized their 20-year-old refrigeration system needed an energy efficiency upgrade. They tackled the challenge in cooperation with process cooling and thermal energy management expert Berg Chilling Systems Inc. Together, along with vital contributions from several highly regarded engineering and technology organizations, they produced a cooling system that reduced peak demand by 45% and saves more than $300,000 annually.
