COMPRESSOR CONTROL SYSTEMS
Regulus® R2000
The Regulus R2000 is an advanced PLC-based centrifugal compressor control system designed for industrial and engineered air compression applications.
Combining flexible control configurations with Energy Advisor, Maintenance Notifications, and intuitive operator controls, the R2000 helps optimize compressor performance and support proactive maintenance. Optional FS-Connect IIoT remote monitoring provides additional visibility into equipment operation, helping facilities improve efficiency and reliability.
Features & Benefits
A highly configurable control system, the Regulus R2000 focuses on improving energy efficiency and enhanced user accessibility with a feature-rich design.
Deliver the Air You Need With Less Waste
Unnecessary pressure and excess air production can increase operating costs. The R2000’s pressure and capacity control modes help match compressor output to system demand, while Pressure Band Optimization supports operation around the minimum pressure your system requires.
The integrated Energy Advisor feature further supports efficiency by monitoring compressor performance and providing tailored recommendations to optimize operation, manage energy consumption, and identify opportunities for additional energy savings.
Put Your Operators in Control
The R2000’s 7-inch color touchscreen brings compressor controls and operating information together in a familiar, tablet-style interface. Operators can review conditions and access settings in one place, making everyday monitoring and adjustments more straightforward.
For greater visibility beyond the control panel, the R2000 also offers optional FS-Connect remote monitoring. This technology provides access to compressor operating data and performance insights remotely, helping teams monitor equipment health, identify potential issues, and make informed maintenance decisions to maximize uptime and reliability.
Recognize Conditions That Need Attention
Visibility into compressor conditions helps your team respond when operation changes. Available temperature, vibration and filter monitoring provides information to support troubleshooting and maintenance decisions.
Alarm and trip notifications alert operators to conditions requiring attention, supporting a timely response and helping safeguard equipment.
Coordinate Compressors Around Plant Demand
For facilities operating multiple centrifugal compressors, optional Integrated Compressor Control (ICC) coordinates lead and lag compressor operation according to changing system demand, helping minimize unnecessary air production, reduce bypass, and support efficient compressed air management.
Optional Ambient Compensation Control (ACC) adjusts the compressor’s surge control line in response to changing ambient conditions, helping maintain stable operation and support efficient performance across varying operating conditions.
Versatile Control for Industrial and Engineered Applications
The R2000 combines advanced PLC technology with flexible configurations to meet the needs of both standard industrial and more demanding engineered applications. Featuring Energy Advisor, Maintenance Notifications, and Pressure Band Optimization as standard, the R2000 helps improve efficiency and reliability.
Additional options, including expanded control capabilities, redundant components, and specialized enclosure configurations, provide greater flexibility to meet specific operational requirements.
