Variable-speed drives

Schneider Electric designed the new Altivar 212 variable-speed drive and the S-Flex enclosed version to provide OEMs and control panel builders with energy-efficient and economical solutions for pump and fan applications.


Altivar 212Schneider Electric designed the new Altivar 212 variable-speed drive and the S-Flex enclosed version to provide OEMs and control panel builders with energy-efficient and economical solutions for pump and fan applications. These ac drives adjust motor speed to the required flow of air or fluids, reducing energy costs by 50%. Electronic motor controls decrease the mechanical stress on belts, piping, and ductwork with no need for valve or inlet guide vane maintenance. Embedded reduced harmonic technology reduces the wire size and the size of upstream overcurrent protection devices and operates 10% more efficiently than typical ac drives.

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.
