R-407C is a blend of refrigerants that offers a good balance of thermodynamic properties, including a moderate boiling point, high latent heat of vaporization, and low pressure ratio. These properties make it well-suited for use in commercial refrigeration systems, such as those found in supermarkets and cold storage facilities. R-407C is also a non-ozone-depleting refrigerant with a low GWP, making it an environmentally friendly choice.
