CCH Custom Build 40ft ISO Frame — 108,000L Cryogenic Storage

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

The listing does not provide current vacuum readings or net evaporation rate data. Request the most recent vacuum gauge reading (typically measured in microns) and NER expressed in percent-per-day or gallons-per-day for the specific cryogen. On perlite-insulated tanks, rising NER or degraded vacuum usually indicates moisture intrusion or a failed neck tube, both of which require vendor service to address.

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

The listing does not confirm data plate condition or documentation availability. Request photos of the data plate showing the National Board number, ASME code stamp, MAWP, and build date, and ask whether the U-1A manufacturer's data report and any subsequent RT-1 repair forms are available. The U-1A is typically required for re-stamping or jurisdictional acceptance if you're relocating this across state lines or into a facility that requires ASME certification verification.

What is involved in relocating and re-commissioning it?

Standard ISO dimensions (40' x 8' x 9'6") allow transport on flatbed with standard securement, though height may require route survey for overhead clearances. At the new site, you'll need a concrete pad rated for the loaded weight, utility connections for the dual HBVP-54K-AL vaporizers (typically electric or steam), and compliance with NFPA and local setback requirements. Before filling, expect vacuum verification, pressure testing per CGA standards, and relief valve recertification or replacement depending on jurisdiction and prior service.
