700 PSI 2,000 SCFH N2 Vaporizer

Is this sized for my peak demand or my average?

Ambient vaporizers are typically sized for peak demand, but continuous operation and ambient temperature below 32°F can reduce output significantly—often by 30-50% in winter conditions. The 2,000 SCFH rating for this unit represents nameplate capacity under design conditions, which are not specified in the listing. If your application runs continuous duty or you're in a cold climate, ask the seller for the performance curve showing flow vs. ambient temperature and inlet pressure.

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

This is a new 2023 unit, so there is no prior service history constraining its use. Aluminum-construction ambient vaporizers are generally suitable for nitrogen, argon, and oxygen service, though oxygen requires specific cleaning and material compatibility verification. Ask the seller whether this unit has been cleaned for oxygen service if that's your intended application.

What are the installation and utility requirements?

Ambient vaporizers require no utilities—they rely entirely on atmospheric heat transfer through the aluminum fins. This unit has 1" Swagelok connections and measures 21' x 21" x 149", weighing 130 lbs. You'll need adequate vertical or angled mounting space with unrestricted airflow around the fins, structural support for the weight when full of liquid, and compliance with setback requirements per NFPA 55 or local code for the gas in service.

What should I inspect on a used vaporizer before buying?

This unit is listed as new, so typical used-equipment concerns like fin corrosion, impact damage, and prior hydrostatic test records don't apply. The listing states it has been hydrostatically tested to 770 PSI. For any vaporizer, verify the nameplate matches the stated model, confirm Swagelok fittings are undamaged, check that all documentation including the hydrostatic test certification and material certs are available, and ask whether it has been cleaned for oxygen service if that's required.
