CPI ISO Frame Unit — 34 Gallon 5500 PSIG ASME Vessel

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

The listing does not provide the current vacuum level or normalized evaporation rate for these units. Request recent vacuum and NER readings from the seller, along with the date those measurements were taken. On cryogenic vessels of this type, vacuum degradation is the primary long-term wear mechanism, and current readings are essential to assess remaining service life.

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

The listing confirms ASME certification but does not address data plate condition or documentation availability. Request photographs of the data plate and confirmation that the U-1A manufacturer's data report is available, as both are required for most jurisdictions and for any recertification or pressure vessel inspection work.

What is involved in relocating and re-commissioning it?

The unit is mounted on a 20" x 20' ISO frame, which simplifies transport via standard flatbed or intermodal equipment. Re-commissioning typically requires a current external and internal inspection per the National Board Inspection Code, pressure testing if the vessel has been out of service, and verification that vacuum and insulation performance meet the intended duty cycle. Jurisdictional requirements vary; confirm whether your state requires re-stamping or just an inspection report for a used ASME vessel being placed back into service.
