Taylor Wharton HSH-17500 — 17,500L Horizontal Hydrogen Storage Tank

What is the current vacuum reading, and what is the NER?

The listing does not provide the current vacuum reading or normalized evaporation rate (NER) for this tank. Request the most recent vacuum pressure measurement in microns and the NER in percent per day from the seller. On new hydrogen tanks, typical NER values run 0.3–0.6% per day depending on insulation design and hold time, but the actual figure for this unit should be verified.

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

This tank is new and has not held product. It was built specifically for hydrogen service with VJ-spec piping and materials. Hydrogen-rated vessels can typically handle other cryogenic gases, but the dual pump piping configuration and materials selection are optimized for hydrogen and any conversion would require review of metallurgy, relief sizing, and piping compatibility with the target cryogen.

Is the data plate legible, and is the U-1A available?

The listing does not confirm data plate condition or U-1A availability. Request photos of the data plate and a copy of the ASME U-1A Manufacturer's Data Report from the seller. Since this is a 2023 tank in new condition, both should be present and legible, but verification is necessary for code compliance and re-registration.
