Thermax SG140HF — 10,920 gal Vertical Cryogenic Storage Tank

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

The listing does not provide vacuum level or net evaporation rate data for this tank. Both metrics are critical for assessing insulation performance and operating cost—ask the seller for the most recent vacuum reading in microns and the NER in percentage per day, ideally with documentation of when those measurements were taken.

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

The listing notes that inventory condition is unknown and the tank was looked for but not located, so data plate condition and documentation availability cannot be confirmed. Request verification that the nameplate is intact and legible, and ask whether the original U-1A form and any requalification records are available—the U-1A is required for jurisdictional acceptance and insurance compliance.

What is involved in relocating and re-commissioning it?

The listing indicates the tank was not located during inventory check, so its current physical status and accessibility are uncertain—confirm with the seller that the unit is actually available and determine whether it is installed or already removed. Recommissioning a vertical cryogenic tank typically requires vacuum integrity testing, pressure vessel recertification if out of interval, relief device inspection or replacement, and product-specific cleaning if changing service.
