R744 (CO₂)

• 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.

• Available from A‑Gas and wholesale partners.

• Store cylinders in a cool, dry, well-ventilated area, out of direct sunlight

• For available package sizes please contact A-Gas on 0800 992 427 or via the Contact Us form

• 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

• Low moisture content to meet AHRI 700 specification, less than 10 ppm

• Industrial grade R744 (CO₂) has an average water content of up to 10 times higher than the R744 (CO₂) available from A‑Gas which can result in the formation of carbonic acid - 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
