This is a containerized 10x10 enclosed LNG control center originally built for a standalone LNG public fueling station project. It is prewired and based on Allen-Bradley CompactLogix and GuardLogix safety PLC architecture with extensive standard and safety I/O. It is suited for buyers who need a ready control foundation for an LNG station, remote automated site, or an industrial project where safety interlocks and structured I/O capacity matter. Originally designed as an LNG station command center with PLC-based automation and safety controls, but suitable for a wide range of cryogenic, industrial gas, and process control applications.
Equipment Overview and Description
This 10x10 industrial-grade enclosed control center was originally designed for a standalone LNG public station for a major U.S. energy company. It was engineered with redundancy, reliability, and real-world safety applications in mind. Built inside a heavy-duty container, it is prewired and preconfigured with Allen-Bradley CompactLogix and GuardLogix PLC systems and remote-ready communications.
This is not a basic panel. It is a turnkey, customizable industrial control system with extensive I/O options, safety-rated modules, and remote-ready infrastructure. It includes four fully populated PLC racks with a dual PLC setup, including a dedicated Safety PLC (1768-L43S). It is prewired for redundant power, control logic, and safety interlocks.
Data Logging
The PLC time-stamps and logs alarms and operational events. Other events are also recorded as listed in the Data Logging List.
