Bell Canada

In 2012, M&M Carnot partnered with Bell Canada to create a cooling system that would maintain the company’s business-critical data centers. Rigorous discussions with the customer, excellent lab results, and innovative technology yielded a highly cost-effective solution that increased sustainability.

With an exponential growth in data traffic comes the need for clean, efficient, and sustainable cooling technologies to expand data rooms. In 2012, Bell Canada was facing a big challenge: most of their server room cooling systems were using synthetic refrigerants — either HCFCs or HFC. The company needed to find an alternative cooling solution that was both sustainable and cost-effective.

Data Center


A suitable alternative to synthetic refrigerants, M&M Carnot’s patented AQUILON™ technology cools data center rooms without the requirements of a compressor, pump, or added fresh air. By using R-744, a natural refrigerant, the AQUILON™ solution was sustainable, cost-effective, and eliminated any future phase-outs.


Bell Canada currently runs forty-four AQUILON™ units across their twenty data centers. The solution has proven its reliability and efficiency by decreasing energy consumption for cooling by up to 80%. What’s more, this innovative cooling system runs 90% of the year in free-cooling. Bell Canada’s AQUILON™ units delivered a positive cost-benefits ratio and have increased overall profitability with an average ROI in three years.
