CCH Custom Build VPC-40K — 40,000 gal Wax Cryogenic Storage Tank

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

The listing does not provide current vacuum reading or Normal Evaporation Rate data. Request the most recent vacuum measurement in microns and the NER in gallons per day or percentage of capacity — both are critical indicators of insulation integrity on a wax-insulated vessel of this age and size.

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

The listing does not confirm data plate condition or U-1A form availability. Request photos of the nameplate showing manufacturer's serial number, ASME code stamp, MAWP, and year of manufacture, plus a copy of the original U-1A Manufacturer's Data Report — these are required for jurisdictional pressure vessel registration and any future rerating or repair work.

What is involved in relocating and re-commissioning it?

At 72" x 72" x 266" this unit will require crane offload, heavy haul permitting, and escort in most jurisdictions. Re-commissioning typically includes foundation and anchor bolt installation, vacuum pump-down to verify insulation performance, pressure testing per jurisdiction requirements, relief valve recertification, and instrumentation calibration before returning to service.
