Technical Gas R-404A — practical grade for everyday engineering work
Technical gas R-404A from REAL GAZ is a workhorse refrigerant grade for maintenance and engineering tasks where laboratory-level analysis is not required.
It is still checked for weight, leaks and basic contamination before dispatch.
It is still checked for weight, leaks and basic contamination before dispatch.
Supply is classed under ISO 817 as a non-flammable refrigerant, handled per EN 378 and moved under ADR for technical and maintenance users.
Not every job calls for the same grade. When a technician is topping up a known system with a small loss of charge, a clean, dry service grade is entirely appropriate, and paying for extended analytical documentation would add little. On the other hand, a critical process or a manufacturer's warranty may require a higher specification, and our staff will say so honestly. The aim is to match the grade to the task, avoid waste and keep the refrigeration plant dependable for its owner. Good record keeping of every charge added also helps customers show that their plant is maintained responsibly. Whatever the grade, work with clean gauges and hoses, vent nothing to the atmosphere, and return any unused gas to us or a recovery point rather than keeping part-filled cylinders for years.
🏭 Where Technical Grade R-404A Is Used
- 🔧 Routine maintenance — periodic top-ups on freezers and cold rooms are the most common use;
- 🏗️ Installation work — first charges on new commercial refrigeration systems are completed with standard service grade;
- 🛠️ Leak repair — after brazing or component change, circuits are evacuated and refilled;
- 🧯 Emergency call-outs — technicians keep cylinders in stock to restore failed cold rooms quickly.
