600PSIG Theramax Inc. Vaporizer Model SG14OHF

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

The listing does not state what gas this vaporizer previously handled. In general, oxygen service equipment cannot be converted to hydrocarbon or other incompatible gases due to contamination risk, while units that ran nitrogen, argon, or CO2 can often be cross-assigned after cleaning and inspection. Request the previous service gas and any cleaning or material certifications from the seller.

What are the installation and utility requirements?

The listing does not provide dimensions, weight, connection sizes, or utility requirements for this unit. Ambient vaporizers typically require only inlet and outlet connections and structural support, with no external heat source, but fin arrays can be large and require adequate clearance for airflow. Ask the seller for a dimensional drawing, shipping weight, connection sizes, and any foundation or clearance requirements.

What should I inspect on a used vaporizer before buying?

The unit is available for inspection by appointment during normal business hours in Waxahachie, TX. On ambient vaporizers, inspect fin-to-tube joints for cracks or separation, check the coil for impact damage or corrosion especially at the bottom where moisture collects, verify all nameplate data is legible, and review hydrostatic test records and the date of last recertification if pressure-vessel stamped. Request documentation of the test pressure result stated as 660 PSIG and any vessel certification or inspection history.
