New 5,000 SCFH 12,000 PSIG Ultra-High-Pressure Ambient Vaporizer — A8SS-9.3

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

The listing does not provide vacuum level or normalized evaporation rate data. Request current vacuum pressure (typically measured in microns or torr for these vessels) and the NER in percent-per-day, along with the date of last measurement. On UHP cryogenic tanks, vacuum degradation is the primary indicator of insulation performance, and an NER above 1-2% per day typically signals that re-evacuation or inner vessel repair is needed.

What is involved in relocating and re-commissioning it?

Moving a 48" x 120" tank typically requires flatbed transport with proper blocking, though the listing does not specify rigging points, total weight, or whether the unit can be transported horizontally. Re-commissioning usually involves pressure vessel inspection per the jurisdiction's interval (commonly 5-10 years for ASME tanks), hydrostatic or pneumatic testing to 12,000 PSI MAWP, vacuum and NER verification, relief valve recertification, and registration with the local boiler authority. Ask the seller for the last inspection date, current registration status, and whether relief valves and instrumentation are still installed.
