What gases can the DRX-0075-122 be used with?

Breathing air, nitrogen and other industrial gases — specify the gas medium when ordering.

How much lighter is the DRX-0075-122 than a steel cylinder?

At 0.54 kg the DRX-0075-122 weighs roughly a third of an equivalent steel cylinder of the same water capacity.

What is the service life of the DRX-0075-122?

—, tested per Manufacturer specification.

Can the DRX-0075-122 be ordered at a lower safety factor than 3.0?

Yes. Catalog ratings use a burst safety factor of 3.0; for R&D and qualification-by-project programs the same structure is quoted at customer-selected safety factors (e.g. SF 2.5, SF 2.25, SF 2.0) with the working pressure derived as burst ÷ SF — ordered as DRX-0075-122-SF2.5 and so on. Derived ratings are engineering configurations, not certified ratings.

R&D configurations — reduced safety factor

Catalog ratings use a burst safety factor of 3.0 (burst = 3 × working pressure). For R&D, space and qualification-by-project programs, the same structure can be operated at a customer-selected safety factor: the burst pressure of 1320 bar is fixed by the structure, and the working pressure is derived as WP = burst ÷ SF. Derived ratings are engineering references — CE/π certification applies at SF 3.0 only.
