✅ Key Benefits & Applications

✅ Direct Replacement for R‑404A/R‑507 in DX equipment: supermarkets, cold rooms, transport chillers

➕ Efficiency Gains: 5‑15% lower energy use vs. R‑404A; up to 15% greater capacity

🔧 Retrofit Ready: POE oil-compatible; typically no component changes needed; requires only liquid-phase charging to prevent fractionation

📉 Lower Discharge Temperatures: Enhances compressor life

✅ Also replaces: R‑22, R‑407 series — following OEM retrofit guidance

📦 Regulatory & Handling Guidance

Governed under EU F‑Gas Regulation 2024/573 and U.S. EPA SNAP listing

Charging: Must be off cylinder as liquid; use recovery tanks rated 300 psig+ for servicing

Storage: Store cool (<50 °C), upright, in ventilated areas; avoid ignition sources

Safety: Use PPE to prevent frostbite; avoid high concentrations that may cause asphyxiation
