GeoStar’s Sycamore Series geothermal comfort system combines a variable capacity compressor with a variable speed blower motor and a variable speed loop pump to provide energy-efficient comfort, while protecting the environment. The use of variable technology allows the unit to scale output to exactly the level needed, rather than running at one or two speeds, like the majority of HVAC systems. Available in 3- to 5-ton capacities, the Sycamore Series achieves an energy efficiency ratio (EER) of 41 and a 5.3 coefficient of performance, which represents efficiencies more than twice that of ordinary heat pumps or air conditioners and a third higher than current two-stage geothermal heat pumps. The Aurora control board offers true two-way communication between components, intelligent operating logic, and powerful troubleshooting capabilities. The unit controls and monitors system conditions and can even determine when excess heat is available to route to the water heater. This option enables the Sycamore to generate supplemental hot water from energy that would otherwise be wasted.
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.
