Industrial R-404A Gas — reliable HFC refrigerant for commercial cold chains
Industrial R-404A gas from REAL GAZ is a non-flammable HFC refrigerant blend of R-125, R-143a and R-134a, widely specified for low and medium temperature commercial refrigeration plant.
Each lot is filled from controlled-purity stock, weighed on calibrated scales and sealed with a tamper-evident valve outlet.

REAL GAZ supplies this refrigerant in line with ISO 817 classification, EN 378 safety practice and AHRI 700 purity limits, suitable for industrial and service use.
R-404A became a standard choice in the late 1990s as a replacement for R-502 and R-22 in low temperature duty, because it combines good capacity with a very small temperature glide. It is rated A1 by ASHRAE, has zero ozone depletion potential and works with POE oil. Its global warming potential is high, so tight systems, regular leak checks and careful recovery are essential. REAL GAZ cooperates with plant owners who are planning a gradual move to lower-GWP alternatives while keeping existing equipment running safely.
🏭 Where Industrial R-404A Is Used
- ❄️ Cold storage warehouses — large condensing units and rack systems holding chilled and frozen stock at set points from −35 °C to +5 °C rely on a stable R-404A charge;
- 🍖 Food processing lines — blast freezers, spiral freezers and brine chillers in meat, fish and bakery plants use the blend for fast pull-down;
- 🚛 Refrigerated transport — truck and trailer units, as well as container reefers, are serviced with R-404A where the original design requires it;
- 🏪 Supermarket display cases — multiplex racks serving open and closed freezer cabinets are topped up with correctly specified refrigerant.
💡 Why Choose REAL GAZ
- ✅ Consistent composition — every cylinder is blended and checked so that the 44/52/4 weight ratio stays within tolerance;
- 🧪 Low contamination — moisture, acidity and non-condensable gases are controlled to avoid oil breakdown and valve freezing;
- 🎯 Right pack for the job — cylinder sizes are matched to the size of your plant, so you waste less gas between charges;
- 🔒 Traceable lots — each cylinder carries a lot number that links back to filling and analysis records.
- 📄 Certificate of Analysis (CoA) — supplied with every order.
📘 Technical Notes for Technicians
- normal boiling point is about −46.5 °C with a very small temperature glide;
- charge in the liquid phase only, because the blend is zeotropic by nature;
- use polyolester (POE) lubricant, never mineral oil, in HFC systems;
- check local F-gas and refrigerant rules before ordering, as permitted use varies by country.
🔬 Quality Control & Safety
- multi-stage purification and drying;
- precision weighing of blend components;
- moisture & impurity analysis;
- leak testing and pressure integrity checks.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
