Further Information

Linde is one of the largest suppliers of carbon dioxide in the world, with a substantial global production and distribution network. We are able to produce a wide range of product qualities for use in industrial processes, up to 6.0 quality, with very low moisture levels, if necessary.

As a leading supplier of refrigerant gases, The Linde Group is committed to supplying the right refrigerant for your business. Although the standard universal specification for R744 is currently under review, we are aware that the moisture content is critical in refrigeration systems. Therefore Linde offers refrigerant grade R744 carbon dioxide in many markets. This product has extremely low levels of moisture, normally below 10ppm by weight. Industrial grade carbon dioxide does not meet this requirement.
