Finalist in HVAC/R in Consulting-Specifying Engineer's 2011 Product of the Year competition
Danfoss’ Performer variable-speed drive (VSD) integrates power electronics and scroll technology. The VSD features a high-capacity scroll compressor for R-410A refrigerant and a variable-frequency drive to deliver the capacity required for constant cooling. With a delivered capacity range for the residential market from 3 to 5 tons, the product can achieve energy savings up to 20%. The drive’s design eliminates the need for an electronic printed circuit board on the outdoor unit or a start capacitor.
The product features an internal permanent magnet (IPM) synchronous motor and exact temperature control of +/- 0.2 F.
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.
