CCH Custom Build VPC-70K-AL — 70,000 L Cryogenic Storage Tank

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

The listing does not provide vacuum reading or normal evaporation rate data. Request current vacuum level (typically measured in microns) and NER percentage from the seller, along with the date those measurements were taken. On tanks this age, vacuum degradation is common and affects hold time significantly.

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

The listing does not confirm data plate condition or document availability. Request photos of the data plate and confirmation that the original U-1A form and any U-3 recertification records are available. These are required for re-stamping and jurisdictional acceptance in most states.

What is involved in relocating and re-commissioning it?

At 96" diameter this tank will require oversize permits and likely police escort in most states; route surveys are essential to clear overpasses and avoid restricted corridors. Re-commissioning typically includes vacuum testing, leak checks, pressure relief recertification, instrument calibration, and in many jurisdictions an AI inspection before filling—budget several weeks if any valve or instrumentation replacement is needed. Confirm with the seller whether the tank can be safely vented and purged, and whether lifting lugs and saddle bolts are intact.
