Packaging Options

• High-Pressure Cylinders (10L / 40L / 50L):
  Each cylinder is made from high-strength alloy steel, designed and certified for high-pressure gas storage. Cylinders are individually cleaned, vacuum-purged, and inspected to meet stringent safety and purity standards.
• 600L Cylinder Pallet Manifold:
  Ideal for medium-scale applications, this manifold system allows multiple cylinders to be connected and filled simultaneously, ensuring a stable and efficient gas supply with reduced downtime.
• ISO Tank Container (Bulk Supply):
  Suitable for large-scale or continuous gas consumption, our ISO tanks are engineered for secure and cost-effective bulk transportation and storage, meeting international standards for pressure vessels and logistics safety.

All packaging options undergo vacuum cleaning, pressure testing, and comprehensive leak detection prior to filling to guarantee consistent gas purity and operational reliability.

SF6 Sulfur Hexafluoride

is an anthropogenically produced compound, mainly used as a gaseous dielectric in gas-insulated switchgear power installations.

Sulfur hexafluoride (SF6) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on SF6 in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to date. Over a 100-year period, SF6 is 22,800 times more effective at trapping infrared radiation than an equivalent amount of carbon dioxide (CO2). SF6 is also a very stable chemical, with an atmospheric lifetime of 3,200 years. As the gas is emitted, it accumulates in the atmosphere in an essentially un-degraded state for many centuries. Thus, a relatively small amount of SF6 can have a significant impact on global climate change.
