A gas producer in the U.S. was creating five new facilities and needed completely modular skids that could be easily interchanged if necessary without impacting production. Enerflex, an OEM skid builder, developed a new solution that on seamless network connectivity via Allen-Bradley® Stratix® devices. IntelliCENTER® software for motor control centers provides real- time visibility into skid pressure, temperature, level, faults and more. The producer can now use any skid where it’s needed most and review skid performance to improve decision making.
