New Surplus Enclosed Command Center / Controls for Any Project Site Not Just For LNG Station
This is a 10x10 heavy-duty enclosed control center built in 2014 by BW Systems for a standalone LNG public fueling station for a major U.S. energy company. It houses dual Allen-Bradley CompactLogix and GuardLogix PLCs across four fully populated racks—one dedicated safety controller (L43S), one standard controller (L43), extensive safety-rated I/O, and prewired redundant power and communication infrastructure. The system is new surplus, prewired and preconfigured, and sits in Waxahachie, TX.

Questions buyers ask
What capacity and product purity does it produce?
This is a control enclosure, not a production unit—it doesn't produce anything. It houses the PLC, I/O, and safety systems that would command field devices (valves, compressors, dispensers, etc.) at an LNG fueling station or similar industrial site. The dual-PLC architecture with dedicated safety controller (L43S) and extensive safety-rated I/O suggests it was designed to manage a moderately complex process with SIL-rated interlocks, but what capacity or throughput it controlled depends entirely on the field equipment it was wired to.
What utilities, footprint and power draw does it require?
The enclosure is 10x10 feet. The two 1768-PB3 power supplies accept 120/220VAC input and produce 24VDC for the control system; the listing does not specify total amp draw or utility requirements beyond that. Control panels like this typically draw modest power—a few hundred watts to low single-digit kW depending on populated I/O and auxiliary loads—but you'll need the seller to confirm actual load and whether HVAC, lighting, or UPS were installed inside the enclosure.
How long was it in service, how long has it been down, and how was it preserved?
The listing states this is new surplus, which typically means it was built but never commissioned or saw minimal runtime before project cancellation. The unit was built in 2014, so it has been sitting for roughly a decade; the listing does not describe storage conditions, whether components were energized periodically, or if batteries in the controllers have been maintained. Ask the seller for storage environment details and whether PLC battery backups have been replaced, as lithium batteries in Allen-Bradley controllers degrade whether powered or not.
What is realistically involved in relocating and re-erecting it?
This is a 10x10 enclosed control center, so transport will require rigging and a flatbed or comparable truck; confirm with the seller whether lifting lugs or a skid base are present. On-site, you'll need a pad or concrete housekeeping slab, conduit runs to field I/O and power, and Ethernet infrastructure if integrating with SCADA or remote monitoring. Because it's prewired and rack-mounted, the internal hardware is relocatable as-is, but expect to rewrite or heavily modify the PLC logic unless your application closely mirrors LNG dispensing—the safety interlocks, I/O mapping, and HMI tags were all configured for the original project.
General guidance for this type of equipment. Ask about this specific unit in your inquiry — the seller answers directly.
