🌿 R454B Refrigerant | Next-Generation Low GWP Solution
Future-Proof Cooling for High-Efficiency Systems
Meet the R410A replacement——R454B. Fully AIM Act-compliant, our high-purity R454B offers a sustainable, efficient, and safe solution for future-ready air conditioning and heat pumps.
🌍Ultra-Low GWP
Future-Proof Compliance: With a GWP of only 466 (a 78% reduction compared to R410A), R454B ensures your systems meet long-term environmental regulations and carbon-reduction goals.
⚡ Enhanced Efficiency
Superior Energy Savings: R454B offers improved capacity and energy efficiency in many applications, helping end-users reduce operational costs and system wear.
🔄 Seamless Transition
Optimized for R410A Designs: As the closest match to R410A's operating pressures, it allows manufacturers to upgrade systems with minimal redesign while maintaining peak performance.
🛡 A2L Safety Rating
Industry-Standard Safety: Classified as A2L (mildly flammable), it provides a low-toxicity, low-flammability profile that is widely adopted for residential and commercial AC safety standards.
| Technical Property | Specification |
|---|---|
| Chemical Composition | R32 (68.9%) / R1234yf (31.1%) |
| Safety Classification | A2L (Mildly Flammable) |
| GWP (AR4) | 466 |
| Temperature Glide | Approx. 1.5 K |
| Critical Temperature | 77.0 °C (170.6 °F) |
| Packaging Options | 25 lb (11.3 kg) DOT-certified Cylinder / ISO Tank |
It is the preferred choice for Carrier, Trane, and Johnson Controls. With a GWP of 466, it is significantly more "future-proof" against EPA regulations than R32 (GWP 675), making it a long-term industry standard.
Only if it is A2L-certified. Most older machines have internal switches that can spark. For R454B, the U.S. market requires tools that are "intrinsically safe" to prevent any risk of ignition with A2L refrigerants.
Yes, but it’s very small (about 1.5°F). For most residential applications, it behaves like a near-azeotrope. However, for maximum efficiency and system stability, you should always charge it as a liquid from the tank.
