FS-Elliott debuts centrifugal compressor controller

PRODUCT EXCLUSIVE: R1000 automatically adjusts the compressor setpoint based on changes in ambient conditions. As a result, the traditionally static surge control line becomes a dynamic entity.


In an effort to help plant managers better manage energy costs, FS-Elliott Co. has introduced the R1000 centrifugal compressor controller as the latest addition to the Regulus control system line.

The R1000 features Ambient Compensation Control, a local control mode designed to automatically adjust the compressor setpoint based on changes in ambient conditions. As a result, the traditionally static surge control line becomes a dynamic entity, allowing the compressor to be safely controlled closer to the true surge line. This control feature reduces waste by maximizing turn-down and minimizing bypass air, ensuring energy savings at off-peak operation. The R1000 takes compressor control one step further by employing Pressure Band Optimization to avoid unnecessary discharge by optimizing the amount of air produced based on the minimum pressure required to meet system demand.

“The R1000 represents a leap forward and sets a new standard for compressor control systems. The vast majority of end users that utilize the advanced feature set of the R1000 will see significant energy savings over traditional control technology,” said Michael Cobak, FS-Elliott’s manager of engineering services.

Integrated Compressor Control adjusts performance by assigning lead and lag machines according to system demand. Automating a lead and lag control process helps eliminate excessive air production, and minimize bypass air, all while reducing energy consumption.

The R1000 will come standard on FS-Elliott’s Polaris line of centrifugal compressors and is the first control system in the industry to feature a 9-in., full touchscreen display as standard. “Improving the user experience has always been and will always be the focus of all product developments,” said Cobak. “We understand our customers need a controller that is easy to operate; the goal of the R1000 is to allow the compressor to do its job without requiring constant monitoring.”

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
