M&M Carnot, a Johnson Controls product line, engineers natural refrigeration systems using ammonia and CO2 for industrial clients across North America.
M&M Carnot
M&M Carnot operates as a product line within Johnson Controls, focusing on natural refrigerant systems for industrial, commercial, and institutional applications. The firm's founding context is not publicly detailed, but its website highlights over 50 years of experience in ammonia-based solutions and over 15 years of expertise in transcritical CO2. John Miranda serves as Chief Sales Officer. The company's strategy spans multiple refrigeration technologies: ammonia, ammonia-CO2 cascade, and transcritical CO2. It designs, manufactures, builds, and services packaged systems and field-erected systems. Confirmed clients include "some of the world's best-known brands" in food and beverage processing, cold storage, breweries, and ice rinks (per firm website). Geographic footprint is North America. M&M Carnot does not publicly disclose a headcount or financial figures. The firm offers 24/7 emergency support via separate phone lines for ammonia/CO2 cascade and transcritical CO2 solutions. No additional offices beyond the U.S. are listed, and no philanthropic or adjacent vehicles have been identified. Recent corporate structure (as a Johnson Controls product line) is the notable operational context. The key structural differentiator is M&M Carnot's integration within Johnson Controls, a global building-technology conglomerate. This positions the firm as an engineering and equipment entity — not a capital allocator — with access to JCI's distribution and manufacturing capabilities. Succession and governance details are not publicly available.
