Nitrogen-charged air conditioner, heat pumps
Nitrogen-charged air conditioner, heat pumps by Lennox are designed to accommodate ambient temperatures up to 125 F.
Lennox released three-phase nitrogen-charge split system air conditioners and heat pumps. These nitrogen-charged products are designed to accommodate ambient temperatures up to 125 F. The units feature a nitrogen-charged, high-efficiency scroll compressor that is grommet-mounted for quiet operation and protected internally against high-temperature motor overload conditions. Enhanced aluminum fins and copper tubing coils offer high efficiency and capacity; a raised design prevents debris from collecting in the bottom of the coil, preventing loss of airflow. Both the air conditioner and heat pump units are built with a heavy-duty galvanized steel cabinet coated with a baked polyester paint finish for maximum durability. The design also includes a full metal louvered panel coil guard and rounded safety corners. Controls located in the corner post and external gauge ports offer easy installation and service. Finally, a raised base pan with ports installed with the air conditioner offers excellent water and debris drainage.

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.
