R744 refrigerant grade carbon dioxide 03 R744 – used in commercial refrigeration such as in supermarkets. Purity and moisture Moisture in R744 based refrigeration and air conditioning systems will create carbonic acid. This acid then causes corrosion in the steel pipe work. There is also a risk of ice formation that can block small capillary

R-744, also known as CO2, is a natural refrigerant that can be traced all the way back to the 1850s. It began to see widespread usage in the early 1900s and 1920s but eventually declined due to the Great Depression and due to the high pressure that R744 operates under.
