M&M acquires CO2 pioneer Carnot Refrigeration

USA: Maryland-based industrial refrigeration system manufacturer M&M Refrigeration has acquired the Canadian CO2 pioneer Carnot Refrigeration.

Based in Trois-Rivières, Québec, Carnot pioneered the use of CO2 transcritical refrigeration in North America for commercial and industrial applications.

“This partnership firmly establishes our position as the leader in CO2-based refrigeration by combining M&M’s industry-leading cascade solutions with Carnot’s innovative transcritical solutions,” said M&M Refrigeration president Chad Riedel. “We will continue to serve our customers by providing refrigeration systems that reduce their operating costs and environmental footprint. In addition, we will be able to expand our collective service and controls offerings.”

Carnot Refrigeration CEO and founder Marc-André Lesmerises, said the company was “thrilled” to partner with M&M to establish “a future where eco-friendly refrigeration is the global standard”. 

“M&M’s complementary market coverage and resources enhance our ability to service the growing demand for green refrigeration and heat pumps,” he added.

Carnot was founded in 2008 as an OEM with a focus on “natural” refrigerants. Over its 11-year history, Carnot has helped to pioneer the use of CO2 transcritical systems in commercial and industrial applications.

Founded in 1969, M&M designs and manufactures industrial refrigeration systems across many applications, including cold storage, food processing, ice rinks, and ground freezing. Claiming to be the first company in the US to implement CO2-cascade refrigeration systems, M&M has offices in Maryland, Florida and Alabama.
