R452A Refrigerant (Low-GWP HFO Blend Replacement for R404A & R507A)
R452A is a next-generation HFO/HFC refrigerant blend (R32 / R125 / R1234yf) developed to replace high-GWP refrigerants such as R404A and R507A in commercial refrigeration and transport applications. With a Global Warming Potential (GWP) of ~2140, it provides a 45% reduction in GWP compared to R404A, while offering nearly identical cooling performance and efficiency, making it a strong candidate for direct system retrofits.
Key Technical Advantages:
Zero ODP with significantly reduced GWP (~2140 vs. ~3922 for R404A)
Comparable capacity and efficiency to R404A/R507A for easy retrofit
Lower discharge temperature extends compressor service life
Compatible with existing POE lubricants—no oil change required
Approved by major compressor and transport refrigeration OEMs
Moderate glide (~2 K) ensures stable and predictable operation
