R744CO2

R744 (Carbon Dioxide) is refrigerant grade CO2. It is environmentally friendly, having zero ODP and an ultralow GWP.

Subject to high operating pressures and low critical temperature.

R744 can be used alongside other refrigerants in cascade systems.

Characteristics

• R744 is only suitable for new specifically designed systems
• The system must be designed to handle high pressure and low temperatures, therefore retrofitting is not suitable.
• Operating pressures up to 10 times higher than R134a
• R774 is a suitable alternative for R134a and R404A applications
• Refrigeration systems that contain R744 require strict controls on contaminants such as moisture and oil. Moisture content must be less than 5ppm.
• Due to extremely high operating pressures, there is risk associated with handling R744.
