Insights & Resources

Understanding Your Compressor Control System Technology
Compressor control technology has come a long way, from mechanical switches and relays to smart, touchscreen interfaces that integrate with plant-wide automation platforms. FS-Elliott’s history in this space mirrors that shift. As control needs became more complex, each generation of FS-Elliott’s systems brought new capabilities to help operators better manage performance, energy use, and maintenance.

Controlling a Multiple Compressor Installation Using Integrated Compressor Control
Integrated Compressor Control (ICC) is a coordinated sequencing feature that allows multiple compressors to maintain a constant system pressure while ensuring maximum energy efficiency and minimal blow-off.
When using the ICC feature, compressors are connected through an integrated Peer-to-Peer (P2P) network. The P2P network, coupled with the ICC sequencing software included in each of the local control panels, allows users to select any of the networked compressors as the master controller, thus creating redundancy and reducing cost by eliminating the need for a separate master controller.

Modernizing Your Compressor Controls: A Practical Guide to Improving Reliability and Efficiency
As facilities continue modernizing their operations, compressor control systems have become one of the most effective areas to improve reliability, energy efficiency, and day-to-day visibility. What began decades ago as simple protection logic has evolved into a plant-wide intelligence platform that helps operators run cleaner, safer, and more efficiently.
This blog highlights how compressor controls have evolved, why modernization matters, and what today’s systems can offer, while our latest Beyond Compression podcast episode takes a deeper dive into the full discussion.
