700 PSI 7,000 SCFH N2 Vaporizer

Is this sized for my peak demand or my average?

Vaporizers are typically sized for peak demand with a safety margin, not average flow. This unit is rated at 7,000 SCFH N2, so if that matches or exceeds your peak requirement you have adequate capacity. Ambient vaporizers can experience reduced output in cold weather or on continuous duty, so consider your geographic location and duty cycle when evaluating the rating.

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

This unit is listed as new condition and rated for nitrogen service. New vaporizers can typically be put into service with nitrogen, argon, or oxygen without prior contamination concerns, though oxygen service requires strict cleaning protocols and material compatibility verification. Ask the seller to confirm the unit's construction materials and whether it has oxygen-clean certification if you need O2 service.

What are the installation and utility requirements?

This is an ambient air vaporizer that requires no utility connections beyond the cryogenic liquid inlet and high-pressure gas outlet, both sized for 700 PSIG service. The unit measures 104" x 44" x 34" and will need adequate clearance for airflow around the fin banks. Ask the seller for connection sizes, weight, and whether mounting feet or a skid base is included.

What should I inspect on a used vaporizer before buying?

This unit is listed as new and was hydrostatically tested to 770 PSI, so typical used equipment concerns may not apply. On any vaporizer, inspect fin condition for corrosion or physical damage, verify all pressure relief devices are in test date, and check tube-to-header welds and tube bundle for leaks or previous repairs. Request documentation of the hydrostatic test and any data plate certifications.
