R-454B is a next-generation refrigerant designed to replace R-410A in new HVAC systems. Offering similar performance with significantly lower environmental impact, it is the preferred low-GWP solution for air conditioning and heat pump manufacturers worldwide. As global regulations tighten, R-454B provides a reliable and future-compliant alternative for high-efficiency systems.
Key Features and Benefits
✅ Ultra-Low GWP Solution
With a Global Warming Potential (GWP) of just 466, R-454B reduces climate impact by nearly 80% compared to R-410A (GWP ~2,088), helping meet international environmental standards.
✅ Excellent System Performance
Delivers comparable capacity and energy efficiency to R-410A while enabling reduced charge sizes and better environmental credentials.
✅ Mild Flammability (A2L)
Classified as A2L – non-toxic and mildly flammable – suitable for use in new system designs built to handle low-GWP refrigerants safely.
✅ HVAC Industry Ready
Widely adopted by major manufacturers for new air conditioning, rooftop units, VRF systems, and heat pumps. Not for retrofit use.
