Is R-448A / R-449A being phased out?

R-448A and R-449A (GWP ~1,400) are not banned but their availability shrinks under EU F-Gas quotas each year. Their price has already risen 3–5× since 2015 and will continue climbing.

How long will HFC refrigerants remain available?

Kigali Amendment phases HFC quotas down 80–85% by 2036. In practice, prices, service availability and insurance costs make new HFC installs uneconomic well before then.

What about R-513A or R-1234ze?

Low-GWP HFO blends (R-513A, R-1234ze) are a legitimate transition option for small commercial plants but face pressure from mildly flammable classification (A2L) and the emerging PFAS restriction. For new industrial cold storage, CO₂ or NH₃ remain the strategic choice.

CO₂ vs Ammonia — Which Refrigerant for Industrial Cold Storage?

CO₂ transcritical and ammonia are the two dominant natural refrigerants for new industrial cold storage. CO₂ wins for medium capacity, retail-industrial hybrids and mild climates. Ammonia wins on efficiency above 200 kW in experienced-operator environments.
