Danfoss has announced that its VLT HVAC variable frequency drive (VFD) and bypass panels have passed rigorous seismic testing, and are now listed as components with Special Seismic Certification Preapproval through the California Office of Statewide Health Planning and Development (OSHPD). VLT HVAC frequency drives feature a modular design that allows users to buy precisely what they need for the specific application. All drives are configured and tested to customer specifications at the factory. With enhanced HVAC-specific capabilities and custom programmability, including integral cascade control, fan control, and compressor control features, each drive is ready for out-of-the-box operation. Integrated fuses and disconnect capability are included in each drive enclosure. VLT HVAC Series drives also feature open communications, enabling them to speak and understand any HVAC language.
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.
