Energy recovery wheel
The energy recovery wheel option by Daikin McQuay recovers 75% of energy from exhaust air steam.
Daikin McQuay introduces an energy recovery wheel option for Rebel rooftop units. This energy recovery option makes the units more efficient, especially for applications requiring large amounts of ventilated air. The energy recovery wheel option recovers approximately 75% of energy from the exhaust air stream. As the wheel rotates, outside air is drawn across one-half of the wheel while exhaust air is drawn across the other half, transferring sensible and latent energy between the ventilation and exhaust air streams. Free heat and humidity are recovered during winter months while free cooling and dehumidification occur during the summer months. Easy, slide-out accessibility to the wheel is provided, simplifying service and cleaning for long-term, efficient wheel operation. The units also exceed ASHRAE Standard 90.1 requirements for energy recovery.
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.
