CCH Custom Build 12.5K-LP — 12,500 Gallon Cryogenic Storage Tank

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

The listing does not provide current vacuum readings or normal evaporation rate data. Ask the seller for the most recent vacuum measurement in microns and the NER in gallons per day or percent per day, ideally with the date of measurement. On vacuum-jacketed cryogenic tanks, vacuum degradation is the primary failure mode and these numbers directly indicate insulation performance and whether re-evacuation or repair will be needed.

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

The listing does not confirm data plate condition or U-1A documentation availability. Request photos of the nameplate showing the ASME stamp, serial number, and original test pressure, along with the U-1A Manufacturer's Data Report if available. Without legible nameplate data and preferably the U-1A, re-certification and jurisdictional acceptance become significantly more difficult and sometimes impossible depending on your local authority having jurisdiction.

What is involved in relocating and re-commissioning it?

The unit is located in Waxahachie, TX and measures 100" x 45" x 90", which will require oversize or specialized transport depending on your route. Re-commissioning typically requires vacuum testing, hydrostatic or pneumatic pressure testing per ASME requirements, relief valve recertification, instrumentation calibration, and inspection by your authorized inspector before filling. The listing notes inspection status is incomplete, so expect to budget time for a thorough engineering assessment and any required repairs before the vessel can be returned to cryogenic service.
