HFC-R507A Refrigerant (High-Performance Azeotropic Replacement for R502)
HFC-R507A is a near-azeotropic blend of R125 and R143a (50%/50%) specifically developed as a high-efficiency, zero-ODP solution for commercial and industrial refrigeration systems. With zero ozone depletion potential and exceptional thermodynamic properties, it has become the industry standard for low and medium-temperature applications where R502 was previously used.
Key Technical Advantages:
Near-azeotropic performance (<1°C temperature glide) ensures system stability and simplified servicing
Superior energy efficiency compared to R502 across all operating conditions
A1 safety classification (non-flammable, non-toxic) per ASHRAE Standard 34
Optimized for low-temperature applications down to -50°C evaporating temperature
Direct compatibility with polyol ester (POE) lubricants
