Danfoss has added the ETS 6 to its series of electrically operated expansion valves. The ETS 6 is designed to control liquid injection into evaporates by regulation refrigerant flow by offering 480 steps from fully closed to fully open and uses precise resolution for better control of superheat, even at low flow rates. The ETS 6 is able to adapt to a system’s exact capacity demands and improves energy efficiency in refrigeration, heat pumps, and air conditioning systems. The ETS 6 is compatible with all common refrigerants including R407C, R410A, R404A, and R134a. The ETS 6 also can be used in heat pump systems with bi-flow 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.
