🌟 Key Benefits & Applications

R‑502 replacement: Emulates R‑502 performance—widely used in low-temp systems (“ice rinks, freezers, cold rooms”)

Flooded Evaporators & Centrifugal Compressors: Azeotrope nature suits complex refrigeration equipment

Energy & Temperature Efficiency: Maintains capacity similar to R‑502 with lower discharge temperature

POE Oil Compatible: Requires synthetic polyol ester lubrication

Recovery-Regulated: EU F‑Gas mandates recovery; regenerated R‑507A allowed until Jan 1, 2030

🚧 Handling & Compliance

Liquid-phase charge only to maintain azeotropic mix—ideal for system consistency

Storage Guidelines: Keep cylinders upright in cool, ventilated areas; avoid heat, moisture

Safety Precautions: Use PPE to prevent frost injury; ensure area ventilation to avoid oxygen depletion

Regulatory Standards: Complies with EU Regulation 517/2014 recovery mandates; new virgin use banned in EU since Jan 2020

📦 Packaging Options

Available cylinders: 1.8 kg, 5 kg, 12 kg, 20 kg, 50 kg, and 740 kg bulk
