Key Features & Specifications
Blend Composition & Global Warming Potential (GWP)
R449A consists of R-32, R-125, R-1234yf, R-134a, and R-1234ze(E). This optimized composition yields a GWP of approximately 1 397, a reduction of around 65 % compared to R404A’s GWP of 3 922. R449A has zero Ozone Depletion Potential (ODP) and meets today’s F-Gas regulations.
Substantially Lower GWP
With a GWP of ~1 397, R449A cuts global warming potential by nearly two-thirds compared to R404A, helping meet corporate sustainability targets.
Maintained Cooling Capacity
Delivers capacity within 95 % of R404A across typical operating ranges, minimizing performance loss and preserving load requirements.
Wide Operating Range
Effective in temperatures from –40 °C up to 10 °C evaporation, making it suitable for ultra-low freezers and medium-temperature display cases.
Reduced Discharge Temperatures
Generates lower discharge temperatures than many legacy blends, extending compressor life and lowering oil degradation.
Non-Ozone-Depleting (ODP = 0)
Fully compliant with the Montreal Protocol and subsequent amendments, ensuring long-term regulatory alignment.
Straightforward Retrofit
Most R404A equipment requires only minor modifications (TXV or expansion device change, POE oil) for R449A compatibility, cutting downtime.

Applications & Use Cases
Commercial Refrigeration Systems
R449A is ideal for:
- Supermarket Display Cases: Consistent temperature control in low- and medium-temperature sections.
- Walk-in Freezers & Cold Storage: Reliable performance down to –40 °C, ideal for meat and seafood storage.
- Multi-Evaporator Installations: Efficient management of multiple zones with varied temperature requirements.
Industrial Cooling & HVAC
R449A works well in:
- Industrial Chillers: Used in food processing, chemical plants, and pharmaceutical cold rooms.
- Packaged HVAC Units: Retrofit older packaged rooftop or chillers transitioning from R407A/R404A.
- Process Cooling: Applications requiring stable performance at moderate low-temperature conditions (–10 °C to 10 °C).
Pressure-Temperature Profile
- Boiling Point (1 atm): –46.4 °C
- Evaporation Pressure at –23 °C: ~1.0 bar (gauge)
- Condensing Pressure at 40 °C: ~16.5 bar (gauge)
These characteristics ensure R449A performs reliably in low-temperature freezers, medium-temperature cases, and multi-evaporator systems.
