New Products for HVAC and Controls
New resources and products for plate heat exchangers.
Plate Heat Exchangers: Design, Applications, and Performances is a new book that provides a general introduction and historical background to the plate heat exchanger (PHE), then discusses construction and operation—PHE types, plate pattern, etc.—and gives examples of PHEs in different application areas. Material issues (plates, gaskets, brazing materials) and manufacturing methods also are treated. The major part of the book concerns the basic design methods for both single- and two-phase flow cases, various flow arrangements, thermal-hydraulic performance in single-phase flow and for PHEs operating as condensers and evaporators.

Brazed plate heat exchangers are tailored for refrigeration and air conditioning systems, can be customized for specific application requirements, and are said to offer an environmentally responsible solution for a wide range of applications. Each exchanger consists of a series of thin, corrugated metal plates that are brazed together to improve heat transfer efficiency. The plates are compressed together in a rigid frame to create an arrangement of parallel flow channels, in which one high-viscosity fluid travels through the odd-numbered channels, and the other high-viscosity fluid flows through the even.

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.
