• R744 (CO₂) is becoming increasingly popular due to its excellent properties

• It has an Ozone Depleting Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1 and is a natural refrigerant

• Available from A‑Gas wholesale partners - find your local distributor for further details

• A‑Gas product cylinders are fitted with a Residual Pressure Device (RPD) to ensure used refrigerant or any other substance cannot be reintroduced into a cylinder

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

• A‑Gas operates a returnable cylinder fleet - empty cylinders are to be returned to an A‑Gas wholesale partner

• For alternative or larger package sizes please contact A-Gas on 1800 002 427 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
