R744 is environmentally friendly, having zero ODP (Ozone Depletion
Potential) and minimal GWP (Global Warming Potential).
R744 also has excellent thermodynamic properties and low energy usage making it suitable for a range of applications such as:
- Industrial heat extraction
- Chilled warehousing
- Shipping vessels
- Commercial refrigeration
- Mobile air conditioning.
One major difference between R744 and other refrigerants is its
pressure/temperature characteristic. Because of its high pressure and
low critical temperature, refrigeration systems require special
Messer - offering combined expertise in carbon dioxide and
Messer is one of the largest suppliers of carbon dioxide in the world, with a substantial global production and distribution network. Messer has the ability to produce a wide range of product qualities that are used in industrial process up to 6.0 quality, with very low moisture levels, if necessary.
As a leading supplier of refrigerant gases, The Messer 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 Messer offers refrigerant grade R744 carbon dioxide (pdf)
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.
One major difference between R744 and other refrigerants is its pressure / temperature characteristic. Because of its high pressure and low critical temperature, refrigeration systems require special equipment designs.
