30 Ft 20 ft ISO + Vaporizer on Flat Bed with Steel Deck

What gases can it be put into service with, given what it ran before?

The listing does not state which cryogenic gas this unit previously handled. Vaporizers used for oxygen service generally cannot be converted to other gases due to strict cleaning and materials compatibility requirements; units that ran nitrogen, argon, or CO2 have more flexibility depending on coil materials and cleanliness standards. Request the previous service history and whether oxygen cleaning was ever performed.

What are the installation and utility requirements?

This unit is mounted on a flat bed trailer with steel deck, so it arrives mobile but you'll need to confirm whether it's suitable for permanent placement or requires blocking and grounding. Ambient vaporizers typically need no utilities other than the cryogenic supply connection, but ask the seller if this unit includes or requires any electrical, water, or compressed air connections for instruments or heat assist. Confirm the ISO frame orientation and trailer dimensions for site access.

What should I inspect on a used vaporizer before buying?

Inspect the finned coil assembly for physical damage, corrosion, and ice buildup patterns that indicate leaks or poor thermal performance. Check all welds, flanges, and the ISO container mounting for cracks or fatigue, especially at frame attachment points. Verify pressure relief devices are in test, review any available test reports for coil pressure drop and outlet temperature performance, and confirm the trailer deck and chassis condition if you're relying on the mobility.
