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
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.
