Cooper Crouse-Hinds’ ACE Series explosion-proof variable frequency drive (VFD) can be safely and reliably installed in Class I, Division 1 or 2 hazardous areas. Currently available up to 60 hp, this drive features a NEMA 7 enclosure with active cooling technology that allows the VFD to be housed inside the classified enclosure without the risk of overheating and failing while operating in ambient temperatures up to 50 C. In addition to installation savings, this drive provides soft start capabilities and built-in, real-time diagnostics. It can lower energy consumption by allowing a motor’s power level to be adjusted exactly to performance needs with an explosion-proof keypad and window.
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.
