Scroll compressor series
The R410A scroll compressor series by Danfoss operate at low temperature ratios for higher efficiency in part-load conditions.
The Danfoss WSH series of R410A scroll compressors are available in six models with cooling capacities that range from 7.5 to 15 TR. WSH compressors are optimized to operate at low temperature ratios, resulting in higher efficiency at part-load conditions—as much as 5% higher when compared to standard air conditioning compressors. In addition, a quick connector plug available on select models saves assembly time and enhances annual productivity by 1%. The plug also helps reduce instances of mis-wiring, enhancing compressor safety and reliability in the process. The WSH series offers a complete range of manifold options that enable customers to choose different tandem and trio combinations in order to meet system capacity and application requirements while reducing installation costs. The series also features an optional acoustic hood, which reduces noise levels by 6 to 8 dB for a quieter environment.

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.
