Inspection, shipping & payment

Inspection Pre-purchase inspections are welcome during normal business hours by appointment arranged in advance. We can provide complimentary transportation from DFW Airport and back if you would like to send someone to see the equipment in person. We can also walk through the item over a video call for domestic or international buyers. We are on US Central Time. Shipping and loading The equipment is located at our yard south of Dallas, Texas. We can assist with shipping arrangements. Loading is provided at no charge for equipment under 15,000 lb when scheduled in advance. Equipment over 15,000 lb requires a crane, which is arranged and paid for by the buyer. Payment Payment in full is required FOB our yard in South Dallas. A verifiable cashier's check is accepted for collection in person. For release to a third-party shipper we require a wire transfer cleared in our account before the equipment leaves the yard.

Questions buyers ask

What capacity, working pressure and NER is it rated for?

Capacity is 2,000 U.S. gallons (7,570 liters) with a design pressure (MAWP) of 40 PSI at -320°F. At full capacity, the unit holds approximately 13,480 lbs of liquid nitrogen, equivalent to 198.4 MSCF of gaseous nitrogen (calculated at 13.803 SCF/liter). No nameplate evaporation rate (NER) is provided in the listing—ask the seller for measured boil-off data or the most recent vacuum performance test results.

What product has it carried, and what can it legally be converted to?

The listing does not state service history or what cryogenic products this trailer has carried. ASME cryogenic vessels can typically handle nitrogen, oxygen, argon, or CO₂ depending on materials and prior service, but cross-contamination and metallurgical compatibility must be evaluated before conversion. Request complete service records and consult the vessel's U-1 form and material certifications before introducing a different cryogen.
