High-efficiency rooftop units
Energence 20- to 30-ton rooftop units by Lennox Industries
Lennox Industries has introduced its high-efficiency Energence 20- to 30-ton rooftop units. These models will replace the Lennox L Series 21- to 30-ton rooftop units, without requiring curb or utility connection modifications. The Energence rooftop units offer higher efficiency levels above their L Series predecessors, with up to an 8% improvement in EER and a 10% improvement in IEER efficiency ratings. They are available in 20-ton gas/electric and electric/electric variable air volume (VAV) models, as well as 25- and 30-ton gas/electric and electric/electric constant air volume (CAV) and VAV models. Most new models exceed the Consortium of Energy Efficiency (CEE) Tier 2 standards.

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.
