CCH Custom Build 55K — 55,000L 700 PSIG High-Pressure Vaporizer Skid

Is this sized for my peak demand or my average?

High-pressure vaporizers are typically sized to peak demand with a safety margin, since LIN/LOX/LAR delivery at pressure cannot rely on surge capacity from a bulk tank's ambient vaporizer. This unit is rated for 55,000L capacity at 700 PSIG. Calculate your actual peak flow in liters per hour (or SCF/hr converted to liquid equivalent) including coincident demand from all users, then verify whether this capacity meets that figure with margin for defrost cycles or fouling.

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

The listing does not state which gas this unit previously vaporized. For high-pressure cryogenic service, prior use matters critically—units that ran oxygen cannot be converted to flammable gases without complete decontamination and often re-rating, and oxygen-clean units require verification of cleaning protocols. Request documentation from the seller on previous service gas and any cleaning or material compatibility certifications.

What are the installation and utility requirements?

The unit is mounted on a 20-foot ISO skid with an 8' x 8'2" footprint and features 1-1/2" x 2" Class 300 RF flange connections. It includes a wax-based temperature control system, which typically requires heat tracing and temperature monitoring but not electrical power for the vaporization process itself. Confirm with the seller whether auxiliary power, control air, or glycol circulation is needed for the specific temperature control implementation on this build.

What should I inspect on a used vaporizer before buying?

Verify current hydrostatic test certification and check the nameplate data against your required MAWP, since high-pressure vaporizers operate as pressure vessels under ASME jurisdiction. Inspect fin condition for corrosion, impact damage, or blockage, and examine all flanges and welds for leakage staining or previous repair. On wax-bath or glycol-bath systems, verify heat exchanger coil integrity and check for evidence of temperature excursions that could indicate coil leaks or contamination.
