CCH Custom Build VPC-10K — 10,000 gallon Cryogenic Storage Tank

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

The listing does not provide current vacuum level or normalized evaporation rate data. Request the most recent vacuum reading in microns and the NER in percentage per day from the seller, ideally with the date of measurement. For vacuum-jacketed cryogenic tanks, typical acceptance thresholds are under 50 microns and NER below 0.5% per day, though these vary by construction and age.

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

The listing does not confirm data plate condition or availability of the ASME U-1A manufacturer's data report. Request photos of the nameplate showing the National Board number and ASME code stamp, and ask whether the original U-1A form is on file. The U-1A is essential for jurisdictions requiring proof of original construction to ASME Section VIII standards and for many insurance and operating permits.

What is involved in relocating and re-commissioning it?

The tank is located in Waxahachie, TX, with dimensions of 48" x 36" x 185", requiring specialized rigging and transport with cryogenic handling experience. Re-commissioning typically includes recertification of pressure relief devices, vacuum and leak testing, NER verification, possible inner vessel inspection depending on jurisdiction and service history, and updated jurisdiction registration. Verify with the seller whether the tank will be purged and whether lifting lugs and original support specifications are documented.
