Sustainable Cooling for High-Density Data Centers
Cooling technologies designed for the next generation of data centers
As data centers grow in scale and power density, operators face increasing pressure to improve efficiency, reduce water usage and prepare for evolving sustainability requirements. MMC Carnot's CO₂-based cooling solutions help meet these challenges with natural refrigerants, integrated free cooling and flexible architectures for both air and liquid cooling environments.
Integrated free cooling, reduced refrigerant costs and highly efficient CO2 operation help lower energy consumption and operating expenses throughout the system lifecycle.
Patented RainCycle™ technology enables extended free-cooling operation, reducing compressor runtime and lowering energy consumption across a wider range of ambient conditions.
Natural refrigerant CO2 (R744) delivers a GWP of 1, helping organizations reduce environmental impact and avoid long-term refrigerant phasedown risks.
- Natural refrigerant CO₂ with a GWP of 1
- Up to 60% lower energy consumption through thermosiphon free cooling
- Reduced refrigerant charge and compact piping architecture
- Natural refrigerant CO₂ with a GWP of 1
- Supports air-cooled and liquid-cooled data center architectures
- Integrated RainCycle™ free cooling technology
- Cooling capacity located directly adjacent to IT equipment
- Supports high-density rack deployments and hotspot mitigation
- Integrated RainCycle™ free cooling technology
