CCH 55K LP — 55,000 gal 700 PSI High-Pressure Vaporizer Trailer

Is this sized for my peak demand or my average?

High-pressure vaporizers are typically sized for peak demand, not average flow, because they serve surge loads during high-draw events or backup scenarios where capacity cannot be deferred. The 55,000-gallon capacity of this unit refers to liquid storage, not vaporization rate; the listing does not specify the vaporization capacity in SCFH or GPM, so you'll need to confirm that figure with the seller to match against your peak requirement. Ambient vaporizers can also experience significant derating in cold weather or high humidity, so factor in your worst-case ambient conditions when evaluating capacity.

What are the installation and utility requirements?

This unit is mounted on a 30-foot 5th wheel trailer, so it requires a suitable tractor for positioning and a level pad capable of supporting the combined weight of the trailer, vaporizer, and full liquid load. The connections are 1-1/2" x 2" Class 300 RF flanges rated for the 700 PSI operating pressure. Ambient vaporizers require no external utilities but do need adequate clearance for airflow around the heat exchange surfaces; confirm local setback and fire code requirements for high-pressure cryogenic equipment in your jurisdiction.

What should I inspect on a used vaporizer before buying?

Focus on the aluminum fin-tube bundle for corrosion, bent fins, or impact damage that reduces heat transfer area, and verify that all pressure-containing components have legible nameplates and are within their requalification interval. This unit has been visually inspected but no hydrostatic test, ultrasonic thickness, or recertification status is mentioned in the listing—request current test documentation and verify the trailer frame, axles, tires, and fifth wheel are roadworthy if you plan to move it. Check all flanges, valves, and instrumentation ports for thread condition, corrosion, or previous repair, and confirm the pressure relief devices are in-date and appropriately sized for your application.
