🌟 Core Benefits

Direct Drop-In Replacement for R‑404A/R‑507 — no need for compressor or TXV changes; matched discharge temperature and capacity

Lower GWP — ~45% less than R‑404A, enhancing environmental compliance

Efficient & Protected: Similar or improved performance with optimal compressor safety

Oil Compatibility: Works with POE oils — popular in R‑404A systems

Easy Maintenance: Liquid-phase charge; allows top-up post-filling

🛠️ Applications

Great for retrofitting or new installation in:

Low- and medium-temperature direct expansion systems

Transport refrigeration (trucks, vans, reefer containers)

Commercial/industrial refrigeration: condensing units, supermarket cases, cold rooms

Storage: Keep cylinders upright, in cool and ventilated areas; near-floor vapor accumulation—use leak detection

Honeywell

Safety: Provide PPE and ventilation to avoid asphyxiation or frostbite; treat leaks as you would R‑404A

📦 Packaging Options

Available via Honeywell, Chemours, A‑Gas, and distributors in typical cylinder sizes (e.g., 11 kg, 25 lb, 46 kg). Dual-port cylinders facilitate liquid take-off
