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.

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
