غاز التبريد (Freeze) نوع (R404A) وزن (10.9Kg)

R404A is a blended, non-flammable refrigerant commonly used in commercial and industrial refrigeration and some HVAC applications. The 10.9 kg cylinder is intended for medium to large systems such as commercial freezers, refrigeration display cases, cold rooms, and industrial chillers. It provides effective cooling across a range of temperatures and is a standard choice for low-temperature refrigeration needs.

Key specs include: composition as a blend of HFC components (typically HFC-125, HFC-143a, and HFC-134a), package size of 10.9 kg, non-flammable (A1) classification, and suitability for professional refrigeration systems. The cylinder is designed with a secure closure to protect contents and ensure safe handling, storage, and transport when used as directed.

R404A is primarily used for low-temperature and some multi-temperature commercial applications, providing strong cooling performance in freezers and display cases. R407C is typically used for air conditioning and mid-range cooling, while R134a is common in smaller refrigeration systems but less efficient at very low temperatures. R410A is widely used in high-temperature air conditioning and heat pumps but is not always ideal for low-temperature commercial refrigeration.

Typical applications include refrigerated display cases in supermarkets, walk-in cold rooms, blast chillers, commercial freezers, and other industrial refrigeration equipment where low-temperature performance is required and R404A is specified by the system manufacturer.

Installation should be performed by a trained refrigeration technician. Ensure your system is designed for R404A, use appropriate recovery and recycling equipment, and charge by weight according to the system’s specifications. Handle the cylinder upright, keep it away from heat sources, and use proper PPE when connecting or disconnecting. Never vent refrigerant to the atmosphere; follow all local regulations for handling and installation.

R404A is a non-flammable refrigerant (A1 classification) but can pose health risks if inhaled in enclosed spaces and can cause frostbite on contact with liquid. Use in well-ventilated areas, wear protective equipment, and follow all local and international regulations (such as F-Gas or equivalent) for handling, storage, and disposal. Ensure licensed personnel perform servicing, charging, and leak checks.

Assess your system’s design, required operating temperatures, and the lubrication/oil compatibility (R404A typically uses POE oils). Consider price per kilogram, package convenience (10.9 kg), and availability for ongoing servicing. If your equipment specifies R404A and you need reliable low-temperature performance, this 10.9 kg cylinder can offer practical value and continuity for maintenance and refilling.

When stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight, R404A cylinders have a long shelf life. Keep the cylinder upright, capped, and protected from physical damage. Regular inspection for leaks or corrosion on the valve is recommended to maintain integrity.

Check that your refrigeration system is designed or approved for R404A and confirm compatible lubricants (often POE oils) and seals. Verify the system’s required refrigerant type and charge amount from the manufacturer. If in doubt, consult a licensed technician to assess compatibility and perform any necessary retrofits.

Common hazards include cold burns from liquid leaks, asphyxiation risk in poorly ventilated spaces, and physical hazards from heavy cylinders. Mitigate by using proper PPE, working in ventilated areas, securing cylinders to prevent tipping, performing leak checks, and following all safety and regulatory guidelines for handling and disposal.

End-of-life handling should follow local regulations. Use certified recovery equipment, avoid venting to the atmosphere, and arrange for proper reclamation or recycling through licensed services. This ensures environmental compliance and minimizes emissions.
