What temperature levels can these systems deliver?

Combined CO2 systems can provide: 

• Freezing: down to ‑40 °C 

• Cooling: ‑5 °C to +10 °C 

• Air conditioning: 6–12 °C chilled water or direct expansion 

• Heating: 35–85 °C water for space heating and hot tap water 

This full spectrum of temperatures is unique to the natural refrigerant CO2.
