CO2 Cascade Refrigeration Systems

Refrigerants : Ammonia/CO2

Industry : Industrial

Since 2004, M&M Carnot has led the U.S. in reintroducing CO2 as a viable refrigerant with almost 100 installed systems. These systems range in capacity between 25 and 1,500 tons for various applications, including process plate freezers, spiral freezers, refrigerated warehouses, and blast freezers operating at temperatures from -60F to +20F.

Customer Benefits

• Combination of two natural, future-proof refrigerants — avoiding regulations limiting use of most synthetic refrigerants
• Two natural refrigerants with zero ozone depletion potential
• Substantially lower installation and operating costs than synthetic systems
• Eliminates ammonia in working spaces, reducing risk for people and food
