Refrigerant R448A overview
Typical applications of R448A:
- Commercial refrigeration (e.g. central rack systems, freezer cabinets and display cases)
- Industrial refrigeration (e.g. food industry cooling processes and large cold storage facilities)
- Refrigerated transport (cooling systems for transport equipment and containers)
Additional information
2025–2029: Virgin refrigerants >2500 GWP are banned. Only reclaimed/recycled >2500 GWP allowed (new appliances). Reclaimed refrigerants with GWP <2500 can still be used for servicing and maintenance after 2032.
