Mitsubishi Electric's W-Series has updated its variable refrigerant flow (VRF) zoning WR2- and WY-Series Modular Water Source Units. Both the WR2- (heat recovery) and WY-Series (heat pump) are available in smaller and lighter units with plate type heat exchangers and both systems operate in either cooling or heating modes. The WR2- and WY-Series systems can be connected to any of the VRF zoning indoor units and can be operated and managed with the CITY MULTI Controls Network (CMCN), which offers a variety of tools and software applications to provide local and centralized control over a building's HVAC systems.
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.
