R-404A Cylinder — safe, traceable packaging for refrigerant
An R-404A cylinder from REAL GAZ holds the refrigerant in a certified pressure vessel with a valve and labelling that suit professional service work.
Cylinders are inspected before every fill, and the contents are weighed to the net mass shown on the label.

Vessels follow ISO 9809 or equivalent design codes, carry TPED marking where applicable and are labelled under EN ISO 7225 for safe handling.
Refrigerant cylinders differ in construction. Disposable cylinders are made for single use and must never be refilled, while returnable cylinders are steel vessels with a protected valve that go through periodic inspection and requalification. Typical contents range from around 10 kg for van work to 50 kg for plant rooms, although availability depends on the market and should be confirmed with our team. The cylinder neck ring or label shows the tare weight, test pressure and next inspection date, which helps you plan returns. Always weigh the cylinder before and after charging, so the quantity added to the plant is recorded accurately.
🏭 Where R-404A Cylinders Are Used
- 🔧 Service vans — technicians carry small and medium cylinders for leak repair, recharge and commissioning visits;
- 🏭 Plant rooms — larger returnable cylinders stay on site for planned top-ups of central refrigeration racks;
- 🏗️ New installations — contractors charge freshly built systems from cylinders placed on scales for accurate dosing;
- 🧊 Retrofit projects — cylinders hold the interim refrigerant while systems are being converted to other gases.
