Additional Information

Packaging and Delivery:

• SF6 is shipped in steel cylinders of 5 L, 10 L, 20 L, 40 L, 43.5 L, and 600 L capacities.
• Tube trailers with up to 13 tons capacity are available for bulk transport.
• Cylinders are equipped with special gas-cylinder valves to ensure safety and prevent contamination​.

Storage Recommendations:

• Cylinders should be stored upright, away from direct sunlight, heat, and open flames.
• Ventilation must be effective at ground level due to the gas’s high density​.

SF6 ReUse Program:

• Solvay offers a recycling process for used SF6, ensuring environmental safety.
• Includes gas collection, analysis, and reintroduction into the production process​.

Compliance and Quality:

• SF6 conforms to IEC 60376, ensuring minimum purity standards (99.993%).
• Manufactured in Germany and South Korea, meeting stringent safety and environmental standards​.
