R744 systems operate at extremely high and dynamic pressures. Even when the system is turned off, the static pressure of R744 is still very high. R744 can displace oxygen if released in excessive amounts (it is heavier than air and can congregate), and therefore precautions must be taken to prevent its release and breathing in of high levels of CO2.

The practical limit[1] of R744 is lower than hydrofluorocarbons (HFCs) because of its potential for high toxicity (HFCs are non-toxic): Practical limit of R744: 0.1 kg/m 3 (56,000 ppm); Practical limit of R404A: 0.48 kg/m 3 (120,000 ppm) R744 (Carbon dioxyde) R744, or carbon dioxide, is making its re-entry into the industrial refrigeration scene. Once thought to be a wasteful chemical requiring too much high pressure to be feasible as a coolant, environmentalists now hail R744 as an answer to growing concerns. Concerns regarding traditional and widely used chemical refrigerants A/C-serviceenheter och tillbehör för R134a, R1234yf och R744. A/C-service. Servicestationer för klimatanläggningar, spolning, rengöring och verktyg . R744 refrigerant can no longer be liquefied through cooling. In such conditions, the refrigerant is therefore continuously air-cooled by the so-called "gas cooler" accommodated in the front end.
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. With an Ozone Depleting Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1, R744 (CO2) is a natural refrigerant. Safety data sheets.
