CCH Custom Build 60K — 60,000 Gallons Cryogenic Storage Tank

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

The listing does not provide current vacuum level or net evaporation rate data. Request recent vacuum readings in microns and the NER in gallons per day or percent per day from the seller, ideally with documentation showing the trend over the last operating period. On bulk cryogenic tanks of this size, vacuum degradation is the primary mode of performance loss, and NER above 0.5% per day typically indicates inner vessel or insulation issues that warrant inspection before purchase.

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

The listing does not confirm data plate condition or availability of ASME Form U-1A documentation. Request photos of the data plate showing the ASME stamp, National Board number, MAWP, and year of manufacture, plus a copy of the U-1A manufacturer's data report. The U-1A is required for most jurisdictions to register the vessel and establish its legal design basis; absence of this document significantly complicates permitting and may require expensive re-certification or prevent installation in some states.

What is involved in relocating and re-commissioning it?

The tank measures 96" × 84" × 257", which requires permits for oversize transport and careful routing to avoid height and width restrictions. Re-commissioning typically involves foundation work, piping connections to the 3/4" ports, pressure testing, vacuum system evaluation and possible re-evacuation if NER is degraded, plus regulatory inspection and registration with the jurisdiction's boiler and pressure vessel authority before filling. Expect several weeks from delivery to operational status if vacuum integrity is acceptable and no repairs are needed.
