About

At M&M Carnot, now a product line of Johnson Controls, our mission is to cool the world by providing customers with natural refrigeration solutions, systems, and controls that are innovative, safe, and sustainable for people and our planet. Our vision is to create and develop global refrigeration systems across all industries that are respectful of the environment, which include industrial, recreational, commercial, and data centers. We strive to ensure that every client has the option of using natural refrigerants instead of synthetic refrigerants that are harmful to the planet. That’s why we’re committed to eco-friendly refrigerants, including Ammonia, Cascade Ammonia-CO₂, and Transcritical CO₂. M&M Carnot has successfully completed the 2024 ATMOsphere Label process and has been reapproved as a best-in-class natural refrigerant equipment manufacturer for the third year in a row.
