CCH Custom Build 36K — 36,000 gal 700 PSIG High-Pressure Vaporizer Skid

Is this sized for my peak demand or my average?

High-pressure vaporizers are typically sized for peak demand, not average flow, because they supply gas at pressures that feed directly into process headers or cylinder filling manifolds where you can't afford brownouts. The 36,000-gallon capacity rating on this unit refers to liquid gallons vaporized per day at standard conditions, but actual throughput will depend on your inlet pressure, ambient temperature, and duty cycle. Ask the seller for the heat exchanger surface area and design outlet temperature to verify it meets your peak flowrate in SCFH.

What are the installation and utility requirements?

This unit is mounted on a 10-foot ISO skid with overall dimensions of 10' x 8' x 8'1" and features a 1-1/2" Class 300 RF flange connection. Ambient vaporizers like this require no utilities beyond the cryogenic liquid supply, but you'll need adequate clearance for the skid, a foundation or pad rated for the loaded weight, and piping to connect the Class 300 flange to your distribution system at 700 PSIG. Ask the seller for the operating weight, any auxiliary equipment like pressure control panels, and whether the unit includes mounting hardware.

What should I inspect on a used vaporizer before buying?

Inspect the heat exchanger fins for physical damage, corrosion, or ice buildup patterns that indicate channeling or poor distribution, and check all flanges and welds for cracks or leaks. Verify that pressure relief devices are in test and ask for hydrostatic test records or ASME nameplate details to confirm the 700 PSIG rating is current. The "2-wax" system configuration mentioned in the listing is unclear—ask the seller to clarify whether this refers to dual heat exchangers, a two-stage vaporization setup, or something else, and request any available maintenance logs.
