Cryoquip BAF-8100-SSL15-SP — 77,000L Fan-Assist Vaporizer

Is this sized for my peak demand or my average?

Ambient vaporizers are typically sized for peak demand with a safety factor, since their output falls off significantly in cold weather, high humidity, or continuous duty cycles. The 77,000-liter capacity rating reflects nominal throughput under standard conditions; actual deliverable flow depends on your inlet temperature, product type, ambient conditions, and duty cycle. Ask the seller for the design flow rate in your units (SCFH or kg/hr) and the basis temperature, and compare that to your peak demand including contingency.

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

The listing does not state what gas this unit previously handled. For vessels rated to 5,000 PSI, prior service history determines what contaminants may be present and whether oxygen cleaning is required—oxygen service demands complete removal of hydrocarbons, while switching from nitrogen to argon is typically straightforward. Request documentation of prior service and any cleaning or recertification records from the seller before committing to a new application.

What are the installation and utility requirements?

Fan-assisted vaporizers require three-phase power for the fan motor (voltage and amperage not specified in this listing) and adequate foundation for the 84" × 84" footprint and 264" height. Typical installations also need isolation valves, pressure relief, concrete pad or structural support rated for the operating weight, and clearance for tube bundle removal during maintenance. Confirm motor specifications, power requirements, and any auxiliary heating elements with the seller.

What should I inspect on a used vaporizer before buying?

The condition and availability of this unit have not been confirmed. On any used ambient vaporizer, inspect the fin tubes for corrosion, mechanical damage, and fin-to-tube bond integrity; check the fan motor, bearings, and blade condition; verify ASME nameplate data matches documentation; and review the most recent hydrostatic test date and results. Request ultrasonic thickness readings on the pressure vessel if the unit is near its next recertification interval.
