High-efficiency rooftop units
Lennox has added 7.5- to 10-ton gas/electric and electric/electric rooftop units that feature an isolated compressor and a slide-out blower for more efficient operations.
Lennox has added high-efficiency 7.5- to 10-ton, gas/electric and electric/electric models to its existing line of Landmark rooftop units. This factory-installed technology uses a variable frequency drive (VFD) to deliver supply fan power savings of up to 61% while still meeting comfort requirements. Additionally, high-efficiency Landmark models may help businesses qualify for state and local utility rebates. The Landmark unit’s flexible design offers more than 100 field customizable options and more than 30 features designed to reduce installation and service time. This includes an isolated compressor compartment for easier, more accurate charge confirmation; a slide-out blower that offers quick belt tensioning, adjustment, or replacement and easier cleaning of the blower wheel; and an accessible gas compartment that simplifies analysis and service.

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.
