VRF for light commercial spaces
The VRF by Mitsubishi Electric Cooling and Heating can operate as low as 22% of total system capacity for maximum energy efficiency.
Mitsubishi Electric US Cooling & Heating Division has added to its variable refrigerant flow (VRF) zoning S-Series cooling and heating systems for light commercial spaces. The updated S-Series PUMY-P60 model is the only 5-ton, single-phase VRF zoning system designed for this market. It can operate at as low as 22% of total system capacity for maximum energy efficiency. Other enhancements include longer line lengths, high efficiencies, and expanded indoor zone capacities. The S-Series outdoor units use INVERTER-driven compressor technology and intelligent microprocessor controls.

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.
