Chiller boosts sustainability
Johnson Controls Inc. introduces YORK model YK-EP "Energy Plus" chiller, designed to reduce the total cost of ownership, improve plant sustainability.
Johnson Controls Inc. has introduced the YORK model YK-EP "Energy Plus" chiller, designed to reduce the total cost of ownership while improving plant sustainability. With a capacity range of 2,500 to 3,200 TR (8,800 to 11,200 kW), the YK-EP chiller is an ideal choice for large chilled water plants. It features a patent-pending, mechanical-compression economizer cycle that provides increased capacity and improved efficiency. The YK-EP chiller delivers energy savings at off-design conditions, where 99% of chiller operating hours are spent. This is due to the chiller's ability to use entering condenser water temperatures (ECWT) as low as 55 F. Off-design performance can be further improved by adding a YORK OptiSpeed variable-speed drive, which can trim the average annual energy consumption by 30% or more.

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.
