AAON SB Series water-source/geothermal heat pump indoor self-contained units (3 to 18 tons) are designed with a double-wall rigid polyurethane foam injected cabinet construction of the SB Series, saving operating costs with reduced air leakage and a higher thermal resistance. Variable capacity scroll compressors and electronically commutated motor-driven variable speed direct drive backward curved plenum fans allow the unit to operate as a energy-saving Single Zone VAV system that modulates fan speed and airflow based on the space temperature and compressor capacity based on the supply air temperature, during both cooling and heating operation.

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.
