R-449A Refrigerant Gas | Alper Refrigerant Gas — Wholesale HFO Refrigerant

HFO/HFC blend for R-404A replacement with significantly lower GWP. Excellent for commercial refrigeration retrofit.

R‑449A – Next‑Gen HFO/HFC Blend for Low & Medium Temperature Refrigeration 🌱

Category: Hydrofluorocarbon/Hydrofluoroolefin (HFC/HFO) blend — a zeotropic refrigerant engineered as a drop-in replacement for R‑404A and R‑507.

✅ Key Highlights & Environmental Profile

Zero ozone depletion (ODP = 0) — chlorine-free blend safe for the environment

Global Warming Potential: Approximately 1,397 (AR4) — about 64% lower GWP than R‑404A (~3,922)

Safety Rating: ASHRAE A1 — non‑flammable, low toxicity

Low glide (~4 K) zeotropic blend — requires liquid-phase charging

🛠️ Blend Composition

R‑32 (Difluoromethane): ~24%

R‑125 (Pentafluoroethane): ~25%

R‑134a (Tetrafluoroethane): ~26%

R‑1234yf (Hydrofluoroolefin): ~25%

🌟 Benefits & Applications

Retrofit & New Systems: Ideal replacement for R‑404A/R‑507 in DX low/medium-temp refrigeration — supermarkets, cold-rooms, condensing units, display cases, transport refrigeration

Seamless Retrofit: Compatible with existing POE-oil systems and hardware; no major equipment changes — just liquid charge and TXV adjustments

Improved Efficiency: Field tests show 8–12% energy savings at medium temps, 2–3% at low temps, plus similar or higher cooling capacity than R‑404A

Sustainability Compliant: Meets F‑Gas and SNAP regulations — GWP < 2,500; promotes reduced environmental impact

📌 Why Choose R‑449A / Opteon™ XP40

Drop‑in efficient retrofit for R‑404A/R‑507 systems.

Significant GWP reduction (~64%) with no ozone impact.

Safety-assured non-flammable A1 rating.

Operational savings via enhanced energy efficiency.

Supported globally by OEMs and refrigerant providers

📦 Handling & Storage

Always charge in liquid phase to prevent blend fractionation

National Refrigerants, Inc.

Store in well-ventilated, cool areas; vapours are heavier than air

Gas Servei

Use with POE oil only — mineral oil incompatibility could harm performance
