Water is a diminishing resource. According to a recent UN report, the frequency and duration of droughts around the world have increased by a third since 2000. The climate crisis is fuelling this increase, it says, and things are likely to get worse: by 2050, more than 75% of the world’s population could be facing water shortages. Right now, humanity is “at a crossroads”, the report concludes, and action to preserve water and mitigate future droughts is urgently required.
The province of Alberta in western Canada is no exception to the trend. “Many Albertans believe this province has an abundant supply of freshwater, but in some parts, water scarcity is already a reality,” says the province’s website. 2021 saw one of the worst droughts in living memory in Alberta, with a major impact on crops.
In response, Alberta is doing its best to save water through education and local initiatives. Typical is the town of Stony Plain, not far from the city of Edmonton. Its environmental stewardship strategy has targeted a reduction in municipal and community water consumption of 20% in the next 20 years. It’s key to Stony Plain’s future sustainability.
In line with this goal, the town’s Glenn Hall Centennial Arena ice rink looked at ways to reduce its own use of water. Skating is an integral and important part of Canadian culture: a survey found that 92% of Canadian parents believe it’s a basic skill that all children should have the opportunity to learn.
“I was on skates by the time I was two years old, and the same with my kids,” says David Fauser, Director of Sales at CIMCO Refrigeration in Toronto. “Skating is part of everyday life in Canada.”
Like Güntner, CIMCO is a company that’s committed to supporting and promoting sustainability in the refrigeration and cooling industry, which meant it was the ideal choice to help the Arena with its water reduction plan. The key to this, Fauser says, was to replace the existing evaporative condenser in the Arena’s cooling system with a Güntner V-shape VARIO Condenser with hydroBLUTM. This intelligent adiabatic condenser employs smart technology, so it only uses water when the ambient temperature requires it. Temperature, water and electricity consumption are all monitored by a GMMnext controller, which automatically adjusts the operating mode to meet the needs of the system.
As Fauser says, “If you can offer a solution that does everything the previous solution does but also conserves water, that makes great sense for clients.”
“AS WELL AS WATER-SAVING BENEFITS, GÜNTNER REPRESENTED THE BEST VALUE FOR THE CUSTOMER BECAUSE IT OFFERED A HIGH-QUALITY SOLUTION THEY COULD TRUST. THE SYSTEM IS MISSION CRITICAL FOR THE ARENA’S OPERATION, SO THEY NEEDED TO KNOW THEY WERE GETTING A PRODUCT THEY COULD RELY ON.”

One year on, the installation of the new Güntner condenser has resulted in a remarkable 98% water saving, compared with the former evaporative condenser. There have also been significant savings in energy expenditure and operating costs.
But as Jascha Heynck of Güntner, points out, it’s not only in areas currently or historically affected by drought where water saving is important. Wherever we live, we need to do all we can to try to preserve this precious resource, and that means adopting new solutions that have been proven to make a difference.
“IT’S NEVER TOO SOON TO START THINKING ABOUT WATER CONSERVATION, AND AS WE’VE DEMONSTRATED IN STONY PLAIN, GÜNTNER’S INNOVATIVE TECHNOLOGY CAN REDUCE WATER CONSUMPTION IN COOLING SYSTEMS BY VERY SIGNIFICANT AMOUNTS.”
