DILO Certified Gas Frequently Asked Questions

Frequently Asked Questions

Does DILO Direct offer disposal of SF6?

Yes, DILO Direct will take your unwanted SF6 gas, recondition the SF6, repackage it and make      it available to use in GIE. This service is designed to give SF6 users an alternative to venting, destroying, or stockpiling SF6 gas contaminated with air, nitrogen (N2) and/or CF4.

How does DILO Direct recondition the SF6?

DILO Direct reconditions SF6 using a system of filters and a SF6 gas separator. Our environmentally friendly separators use a cryogenic process to remove moisture, by-product, and air contaminates from the SF6 Gas.

Can I get my contaminated SF6 gas cleaned and returned?

Definitely! DILO Direct will recondition your contaminated SF6 gas to exceed IEEE and IEC standards. We guarantee > 99% SF6 purity, < 40 ppm moisture, zero by-products. We will provide you with a report of the quality and quantity of the SF6 before and after reconditioning. We also provide customers with a cylinder DOT certification status and send all gas back in in-certification cylinders.  

I’m not sure if my cylinders are in certification. How can I tell? Do I need to take the SF6 gas out?

DOT/ISO cylinders have a test qualification stamped on the shoulder consisting of a month, the testing facility’s identification, and year. In the same area, you might find plus (+) symbol  and/or star symbol. Stamps with and without out a plus are in certification for 5 years from the stamped date. Cylinders with a star are in certification for 10 years.

Certain exceptions do take place. If you’re not sure, please contact us and we will be glad to help.

You do not need to take SF6 out of a cylinder with expired qualification; however, it is not recommended practices to fill an expired cylinder.

Will DILO Direct fill my cylinders with new SF6?

DILO Direct has DILO Certified SF6 for purchase, which has been reconditioned to exceed IEEE and IEC standards. DILO’s reconditioned SF6 gas has the same handling requirements and properties as virgin SF6 when used in GIE, but it has a much lower carbon footprint. We can top off or fill your existing cylinders with DILO Certified SF6.

No cylinders? No problem. DILO Direct can provide you with rental cylinders.

Can I purchase the cylinder?

Yes, DILO Direct offers cylinders for purchase. They can be filled with SF6 gas, or empty (in vacuum).
