CCH Custom Build 26K LP-H — 18,200 gal 700 PSIG High-Pressure Vaporizer

Is this sized for my peak demand or my average?

The 18,200 gallon capacity figure typically represents storage volume, not vaporization rate. High-pressure vaporizers like this are generally selected based on peak flow requirements measured in SCFH or GPM, which the listing does not specify. Ask the seller for the actual vaporization rate at your operating pressure and inlet temperature to determine whether it meets your peak demand.

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

The model designation indicates this unit was built for LNG applications, but the listing does not specify what service it actually ran in. High-pressure aluminum vaporizers can typically handle LNG, nitrogen, oxygen, and argon, though oxygen service requires specific material compatibility and cleaning documentation. Request service history and any oxygen cleaning certifications if you're considering oxygen use.

What are the installation and utility requirements?

This unit has a 1-1/2" T&G flange connection for inlet/outlet. Ambient vaporizers require no external utilities but need adequate clearance for airflow and thermal cycling; finned units typically need several feet of unobstructed perimeter. The listing does not specify footprint, weight, or foundation requirements, which you'll need from the seller for site preparation.

What should I inspect on a used vaporizer before buying?

Inspect aluminum fins for corrosion, impact damage, and bent sections that restrict airflow; check all welds and tube-to-header joints for cracks from thermal cycling. Verify the nameplate matches the 700 PSIG rating and request hydrostatic test records and remaining service life documentation. On high-pressure units, pay particular attention to inlet manifold condition and any evidence of freeze damage from improper operation.
