HFC-R453A Refrigerant (R454B; Low-GWP R410A Alternative with A2L Classification)
HFC-R453A is a mildly flammable, low-global warming potential (GWP) refrigerant blend designed as a next-generation alternative to R410A in new air conditioning and heat pump applications. With a significantly reduced GWP of 465 (approximately 78% lower than R410A) and zero ODP, it offers an environmentally sustainable solution aligned with global regulatory phase-down schedules.
Key Technical Advantages:
Ultra-low GWP (465) meets stringent environmental regulations
Similar cooling capacity to R410A (within -5% to +5% range)
Lower discharge temperatures enhance compressor reliability
Mildly flammable (A2L) classification with proven safety track record
Reduced direct emissions impact compared to HFC alternatives
