Command Center / Controls - Allen - Bradley PLC, AC/Heather, Fire / Server Control - New Surplus Enclosed

Overview: This 10x10 industrial-grade Enclosed LNG Control Center was originally designed for a standalone LNG public station for a major U.S. energy company. It’s engineered with redundancy, reliability, and real-world safety applications in mind. Built inside a heavy-duty container, it’s prewired and preconfigured with high-end Allen-Bradley CompactLogix and GuardLogix PLC systems—ideal for automated LNG sites, remote operations, or integration into larger energy infrastructure.

Panel Builders & Integrators: This is not a basic panel. This is a turnkey, customizable industrial control system with extensive I/O options, safety-rated modules, and remote-ready infrastructure. It includes:

•  (4) Fully Populated PLC Racks
• Dual PLC setup with a dedicated Safety PLC (L43S)
• Pre-wired for redundant power, control logic, safety interlocks
• Ideal for Panel Build Automation Users, safety-focused industries, and LNG infrastructure
