R-744 is often used as a secondary refrigerant along with ammonia, thereby opening up applications where ammonia as a single stage refrigerant would not be applicable.
Environmentally friendly: zero ODP, GWP = 1
Non-flammable, mildly toxic, asphyxiant in high concentrations and odourless
Excellent thermodynamic properties and low energy usage make it suitable for a range of applications, including
industrial heat extraction,
chilled warehousing,
shipping vessels,
commercial refrigeration
mobile air conditioning
