R-404A Refrigerant for AC and refrigeration systems — compatibility and service guidance
R-404A refrigerant for AC and refrigeration systems is supplied by REAL GAZ with attention to what the refrigerant is really suited for, since its design focus is low and medium temperature refrigeration.
Equipment built for R-22 or R-410A should not be filled with it.
Equipment built for R-22 or R-410A should not be filled with it.
Classification follows ISO 817 (A1), system design follows EN 378 and compatibility notes refer to ISO 11114 for systems and materials.
The name AC covers many designs, and R-404A is not a general-purpose air conditioning gas. Comfort cooling splits and chillers most often use R-410A, R-32 or R-134a, which operate at different pressures and with different oils. R-404A is relevant where a system was built for it, such as low temperature units and certain industrial coolers. Before ordering, read the data plate, compare the refrigerant listed and ask us if you are unsure. A short check can prevent costly damage and downtime. We would rather help you confirm the correct refrigerant than supply the wrong one. Our advice is given in good faith, but the equipment manufacturer's data always takes priority.
🏭 Matching R-404A to Systems
- 🧊 Low temperature refrigeration — freezer cabinets and cold stores operating around −25 °C to −35 °C are the core use;
- 🥗 Medium temperature cases — chilled displays and cold rooms around 0 °C to +5 °C also use the blend;
- 🏢 Specialised cooling — selected process and air cooling systems in industry were built around this refrigerant;
- ♻️ Retrofit planning — owners moving to lower GWP refrigerants need a bridge supply during the changeover.
💡 Why Choose REAL GAZ
- ✅ System-first advice — we encourage checking the nameplate and manufacturer data;
- 🧪 Oil-aware supply — the refrigerant is dry, and we advise using POE lubricant with it;
- 🎯 Correct charge method — liquid charging avoids composition shift in the blend;
- 🔒 Responsible handling — recovery into labelled cylinders is recommended for every job.
- 📄 Certificate of Analysis (CoA) — supplied with every order.
📘 Compatibility Checklist
- R-404A operates at higher pressure than R-134a, so components must be rated for it;
- do not top up an R-22 system with R-404A without a full conversion;
- seals and hoses should be HFC compatible;
- check local rules, since use of high GWP refrigerants is restricted in several markets.
🔬 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.
