Liquid Argon ISO Container. 150 psi Water Capacity 20155 Liters, Payload 229.9 KG

What is the current certification status and next inspection date?

The listing states this unit has been freshly recertified and is ready for service. The specific recertification date and next due date are not provided—ask the seller for the inspection report showing the recert date and the applicable retest interval (typically five years for DOT specification portable tanks, though regulatory jurisdiction varies by use and location).

What product has it carried, and what can it be converted to?

The unit is described as a liquid argon ISO tank and has been reconditioned for liquid argon service. Cryogenic ISO tanks can typically carry other inert cryogens (nitrogen, helium, carbon dioxide) after proper cleaning, but conversion to oxygen service requires more stringent cleaning and certification due to oxygen compatibility requirements.

What is the tare and payload at service pressure?

The listing provides payload of 229.9 kg but does not specify tare weight. Ask the seller for the data plate values and current weigh ticket—tare weight is critical for road transport compliance, and the payload figure given may reflect maximum gross vehicle weight limits rather than the container's full volumetric capacity at service pressure.

What should I inspect on a used ISO tank before buying?

Request the current recertification report showing pressure test results, internal inspection findings, and vacuum integrity test data. Examine the inner vessel for corrosion or previous repair welds, verify vacuum jacket integrity (partial vacuum loss severely degrades insulation performance), inspect all valves and instrumentation for freeze damage or packing leaks, and confirm the outer frame has no cracks at ISO corner casting welds or damage that would prevent twist-lock engagement.
