6,000 PSI 15,000 SCFH Vaporizer

Is this sized for my peak demand or my average?

Vaporizers should be sized to peak instantaneous demand, not average flow. The 15,000 SCFH rating on this unit represents its maximum continuous output under the design conditions. Your actual peak demand calculation should account for simultaneous equipment usage, process upsets, and any required safety margin—typically 10-25% above calculated peak depending on the criticality of supply.

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

This is a new 2024 unit, so there is no previous service history limiting its application. High pressure vaporizers in this class are typically used for oxygen, nitrogen, argon, carbon dioxide, and other industrial gases depending on materials of construction. Contact the seller to confirm the construction materials and whether the unit is oxygen-clean or suitable for your specific gas service.

What should I inspect on a used vaporizer before buying?

This unit is new and has been hydrostatically tested to 9,000 PSI. For any vaporizer, verify the test documentation and nameplate data against your pressure vessel code requirements. Inspect heat exchange surfaces for damage or fouling, check all pressure-containing components for corrosion or mechanical damage, and verify that pressure relief devices are present and within their certification dates.
