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 .
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.
