Johnson Controls Acquires M&M Carnot to Enhance Sustainable Industrial Refrigeration Portfolio 

Johnson Controls has acquired M&M Carnot, a provider of natural refrigeration solutions with ultra-low global warming potential, which can help customers meet their sustainability goals while meeting and exceeding environmental regulations.

M&M Carnot designs and manufactures industrial refrigeration equipment and controls that use carbon dioxide, which has a GWP of 1. By contrast, traditional refrigerants can have GWPs in the thousands, magnifying rather than solving the global warming problem.

M&M Carnot will add to the growing portfolio of Johnson Controls industrial refrigeration equipment operating on ultra-low GWP refrigerant CO₂.
