York Sunline Magnum 15- to 25-ton packaged cooling and heating
York Sunline Magnum 15- to 25-ton packaged cooling and heating from Johnson Controls ZJ models feature four independent scroll compressors with individual refrigeration circuits for efficient part-load operation. Four stages of cooling mean more economical and comfortable cooling. ZR and ZF models are two-stage units with two compressors. In all models, vibration and noise are minimized through sound muffling and isolation of the compressors’ internal spring. The energy efficiency ratio (EER) of the line ranges from 10.4 to 12.4. Gas/electric units have electronic spark ignition and power vented combustion with steady state efficiencies (SSE) of 80%. For more information, click here .

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.
