Max Gaz R404A

Max Gaz R404A - Industrial Refrigerant Gas

R404A is a refrigerant gas blend formed by combining three different HFC gases – R125, R143a, and R134a – in specific proportions. It has been a standard in the commercial and industrial refrigeration sector for many years, widely used especially in low and medium temperature applications.

R404A offers high cooling capacity for supermarket display cases, industrial cold storage warehouses, freezers, blast chillers, food preservation equipment, refrigeration cabinets, and two-phase chiller and VRF systems. With an ozone depletion potential of 0 (ODP 0), it is environmentally much safer than older generation gases like R22. However, due to its high GWP value (≈3922), it is subject to certain restrictions under F-Gas regulations. Therefore, while the transition to low-GWP alternatives is becoming widespread for new installations, R404A continues to be used in existing systems depending on technical requirements.

Since R404A is a zeotropic mixture, its components behave differently during evaporation and condensation processes. For this reason, gas filling, transfer, and recovery should only be performed by authorized and trained technicians. Improper interventions can reduce system performance or damage equipment.

As MAX GAZ, we supply R404A gas in fully CE certified, refillable cylinders. All our cylinders are QR-coded, traceable, and compliant with safety standards. Our professional team provides expert support on cylinder size selection, stacking methods, and correct operating conditions suitable for your application area and system capacity.

💬 R404A Refrigerant Gas – Frequently Asked Questions (FAQ)

❄️ General Information

1. What is R404A?
R404A is an HFC refrigerant gas blend consisting of R125, R143a, and R134a. It has been used for years as an industry standard, especially in commercial refrigeration applications.

2. Where is it used?
R404A is widely preferred in supermarket refrigerators, industrial cold storage warehouses, freezers, blast chillers, and low- to medium-temperature commercial refrigeration equipment.

3. Are there alternative gases replacing R404A?
Yes. Due to F-Gas regulations, low-GWP alternative gases such as R448A, R449A, and R452A are recommended for many applications. However, the transition process requires expertise depending on equipment and oil compatibility.

🧯 Cylinder and Safety

4. Can R404A cylinders be refilled?
Yes. As MAX GAZ, we only offer R404A in CE certified, refillable cylinders. Single-use cylinders are not sold.

5. How should cylinders be stored?
They should be stored upright, away from direct sunlight, in cool, dry, and ventilated areas.

6. Are empty cylinders collected?
Yes. Empty cylinders can be returned, or a refilling service can be provided.

⚙️ Usage and Technical Information

7. What is the GWP value of R404A?
The global warming potential (GWP) of R404A is approximately 3922. Therefore, its environmental impact is high, and it is subject to some restrictions in F-Gas regulations. Recovery and correct use are important. It is no longer preferred, especially in Europe, due to its high GWP.

8. Does R404A operate at high pressure?
Yes. R404A can have high-pressure values in low and medium temperature applications. Compatible hoses, connections, and pressure-resistant equipment must be used.

9. What should be done in case of a leak?
If a leak is detected, the system should be shut down, the area should be well ventilated, and an authorized technical service should intervene.

📞 Sales and Support

10. Can I order small quantities?
Yes. We support orders of 1–10 cylinders. Ideal for maintenance teams and small businesses.

11. Are the products compliant with F-Gas and CE regulations?
Yes. All our R404A products comply with F-Gas Regulation and CE standards.
