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
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.
