R744 (CO2)

Summary

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. A-Gas only sources CO2 that is recovered and not produced, so no new CO2 enters the atmosphere, helping you reduce your carbon footprint further.

Product Features & Benefits

  • Refrigerant grade R744 (CO2) is available from A-Gas in gas (vapour) or liquid form
  • Non-flammable with a safety classification of A1
  • Compressors must be charged with modified polyolester oils, contact the compressor manufacturer for more information
  • Excellent thermodynamic properties and low energy requirements
  • R744 (CO2) can be used alongside other primary refrigerants such as hydrocarbon and ammonia
  • High operating pressures
  • Refrigeration systems that contain R744 (CO2) require strict controls on moisture, oil and other contaminants. Contact A-Gas should a CO2 analysis be required
  • Ultra-low moisture content, less than 5 ppm
  • Industrial grade R744 (CO2) has an average water content of up to 10 times higher than the R744 (CO2) available from A-Gas. This can result in the formation of Carbonic Acid and its build up will result in corrosion of machinery and pipework
  • Vapour R744 (CO2) cylinders are available for initial pressurisation of systems, whilst liquid R744 (CO2) provides the required charge your system needs to operate efficiently
