Putting You In Control

With this easy-to-use, multifaceted system, plant operators

are empowered to master one of a facility’s highest operating

expenses—energy costs. Savings are achieved through the

REGULUS® operating system’s superior pressure control

capability, thereby eliminating excessive air blow-offs to

the atmosphere while efficiently responding to the facility’s

changing air demands.

This proven Programmable Logic Controller (PLC) based

system is designed with leading-edge technology processors

and memory capabilities providing performance, reliability and

convenience. At the touch of the Human Machine Interface

(HMI), the operator dictates how REGULUS® monitors,

controls and manages all of the air compressor system’s

needs. Plant operators can perform these functions locally

or from a remote location. The REGULUS® information

management function stores operating data that can be used

for analysis and preventative maintenance. This historical

information is a valuable asset, enabling engineers to identify

and avert potential problems. A serial port allows interface

communication between the REGULUS® Control System and

the User’s Distributed Control System (DCS). If control of the

• Supervisory capabilities include monitoring the entire air system from one location

• Data storage and trend viewing are instantaneously available with the touch of the finger

• The compressor can virtually run unattended at optimum efficiency through various plant air demand conditions

compressor is preferred directly through the DCS, FS-Elliott’s

team is ready to assist with the integration solution including

instrumentation and control logic development. Optional

redundant and fail safe systems can also be incorporated

into the REGULUS® package for end users preferring these

added features.

The REGULUS® Sequencer is an additional FS-Elliott control

system enhancements for facilities that require multiple

unit control and total system administration. This user-

friendly system includes advanced energy management

capabilities that simultaneously control multiple centrifugal

air compressors. Supervisory functions include monitoring

numerous system components such as cooling towers, dryers,

pumps, motor control centers and other auxiliary equipment.

Whatever the need, FS-Elliott’s engineering staff has the

know-how to meet and exceed your requirements with a

REGULUS® Control System.

FS-Elliott’s control systems have been a fundamental part of our equipment

packages since the very first compressor was shipped more than half a century

ago. Thousands of our control systems are operating at high levels of excellence

in facilities located around the globe. It is this incredible depth of experience that

has earned FS-Elliott the reputation as the premier provider of reliable control

technology for centrifugal compressors. Today, every FS-Elliott air compressor has

at its heart one of our advanced REGULUS® Control Systems.

The REGULUS® Control System enables operators to manage air compressor operation with an easy to use yet powerful interface. FS-Elliott offers training programs that include compressor functions and settings to obtain optimum performance.

Innovative Solutions For Today’s ApplicationsMany air compressor operators have specialized needs that require customized solutions. FS-Elliott’s staff has the depth and know-

how to meet the most challenging control applications. The optional REGULUS® is a testimonial to the expertise, flexibility and

reliability that is fundamental to our customer focused marketing approach.

REGULUS® SequencerWith the addition of the REGULUS® Sequencer package, plant operators have the ability to incorporate the most comprehensive

master controller available for multiple compressors. The REGULUS® Sequencer’s unique control methodology assures that

each compressor in the system shares the load against total system demand in the most energy efficient manner. This exclusive

control scheme provides energy savings by making certain that all of the compressors utilize their full turndown capability before

unloading air to the atmosphere. The capabilities also include time-sharing functions and automatic run time equalization.

REGULUS ®: The Quality is Built-in,The Performance is Superior

The REGULUS® Control System includes a comprehensive group of standard

features. In addition, FS-Elliott offers an extensive number of hardware

options that enable you to configure the system to accommodate your

specific needs. These features have been pre-engineered to maintain

standardization and minimize the cost and delivery impact.

• NEMA 4 and NEMA 4X control cabinets are available in carbon and

stainless steel materials of construction.

• The REGULUS® control system is driven by the most current Siemens

and Allen Bradley Programmable Logic Controllers (PLC).

• Control panel cooling modes can be provided with single or dual

vortex and air conditioning units.

• Large touch screen HMI’s for operator ease-of-use.

• Communication capabilities include Modbus®, Profibus, Ethernet and

Teleservice. Remote diagnostics options are also available.

• Available heater devices ensure cabinet component reliability in the

harshest environments.

• The REGULUS® has expansive Input / Output (I/O) module

capabilities. Sensing instrumentation input is processed to provide

precise output signals to control devices located in the main air and

auxiliary systems.

• Air system operational information and set point data is easily stored

on a large capacity memory flash card for future reference and

downloading to a computer.

• A conveniently located USB port is provided to access the REGULUS®

Control System.

Designed & Built to Exceed ExpectationsThe REGULUS® Control System Series Consists of Four Models: R150, R200, R300 and R400

Industrial Series Engineered Series

Typical Industrial Series installations include food and

beverage, automotive manufacturing, pharmaceuticals,

electronic component manufacturing, mining, textiles and

many others. The base model R150 includes a powerful

PLC packaged with control and monitoring features that are

considered optional items on comparable systems. The R150

also includes a Liquid Crystal Display (LCD) touch screen and

multiple language capability. Networking communication

protocol capabilities include Ethernet and Modbus®.

The R200 features include an enhanced PLC and additional

Input/Output (I/O) capacity that increase the base model’s

capabilities and provide for an expanded list of optional items.

The R200’s larger memory provides for advanced trending

and diagnostics while still maintaining the cost benefits of a

standardized design.

For those applications requiring customized solutions, the

REGULUS® Engineered Series is the control system of choice.

Our Engineered Series systems can be found in everyday use

within world-scale Oil & Gas Production, Refining, Chemical

and Petrochemical facilities. The R300 includes additional

I/O modules to accommodate installations with increased

analog and digital input and output requirements. The R300
