R32 Refrigerant (Ultra-Low GWP Successor to R410A)
R32 is a next-generation single-component HFC refrigerant with zero ODP and ultra-low GWP (GWP=675) – 70% lower than R410A. Designed as the sustainable upgrade for R410A systems, it delivers 10-15% higher energy efficiency while enabling 30% refrigerant charge reduction in compliant A2L equipment.
Key Specifications:
Minimal temperature glide (<0.5°C) ensures precise temperature control
A2L safety classification (low flammability) with ISO 5149 compliance
Direct retrofit compatibility with R410A infrastructure (after purge/flush)
Hydrolysis-resistant formulation (moisture ≤0.001%) prevents acid formation
