CO2 is non-flammable 2015-07-16 · R744 vs. Other Refrigerants. Table 1 shows a simple comparison of R744 with other types of refrigerants, including those that are currently commonly used and those that are currently being evaluated for future use. It uses a simple “traffic light” system and employs the common HFCs, such as R404A and R134a as a baseline.

R744 CO 2 has excellent thermodynamic properties and has significant advantages compared to classical and other alternative refrigerants: R744 refrigerant properties: CO 2 is non-corrosive, non-toxic and non-flammable Linde’s cylinders are specially prepared so that our R744 has very low moisture content and low non condensable gas content. Typically, Linde’s R744 is a high purity gas that is over 99.99% pure, with a moisture content of less than 10 parts per million (by weight). Due to the extra work involved in meeting the demanding specification for R744, refrigerant grade CO R744 (CO2) is refrigerant grade CO2, used as a replacement for R134a and R404A in ultra-low, low and medium temperature refrigeration applications. R744 (CO2) is becoming increasingly popular due to its excellent properties.
