Reconditioned SF6 Gas
Used gas with a better quality than new
Thanks to the combination of several DILO gas separation and preparation units, we can process even extremely contaminated SF6 gas with to a purity of > 99 %. This not only exceeds industry's reuse standards, but DILO Certified SF6 Gas also exceeds current specifications for new gas.
DILO Certified SF6 Gas Compared to IES and ASTM Standards
|SF6||> 99 Vol.%||> 98,5 Vol.%||≥ 99,8 wt%|
|H2O||≤ 8 µl/l||< 200 µl/l||≤ 8 ul/l|

|Air||< 500 µl/l||< 10.000 µl/l||≤ 500 ppmw (≙ 2500 µl/l|
|CF4||< 500 µl/l||< 4.000 µl/l||≤ 500 ppmw (≙ 830 µl/l)|
