"Several experts from Tuthill recently spoke with Blower & Vacuum Best Practices Magazine to discuss opportunities for improvement regarding vacuum and blower systems at food manufacturing facilities. During the talks, Adam Crampton, Russ Ristow, and Tim Wilson of Tuthill covered a variety of topics—from the design basics of pneumatic conveying systems, to advanced vacuum optimization opportunities within packaging machines."

Sewage Treatment Plant Retrofits Diffusers to Cut Energy Consumption 50%

"In 2012 when the plant was struggling to keep up with regulatory requirements, the Ilmajoki STP [Finland] was using 4000 kWh per day. Once the new diffusers and control systems were implemented, the plant was able to reduce their consumption and averages to under 2000 kWh per day."

Managing Energy as an Ingredient at General Mills

"Within the “zero-loss” culture at General Mills, plant personnel identify and optimize major energy users in each facility. Common opportunities include: the optimization of dryers, ovens and freezers; compressed air optimization projects; improvements to building heating and cooling system; and lighting replacement innovations. In addition, engineers at General Mills have started to explore new energy-saving opportunities within the vacuum and blower systems at their production facilities. To better understand how any production system is addressed at General Mills, an examination of the company’s energy management methodology is required."

Optimized Power-Demand Control System for Electric Motors

Heating, Piping, Air Conditioning Engineering, Mar. 2016, by Alexander L. Burd and Galina S Burd.

"During off-design load conditions, use of variable-frequency drives (VFDs) reduces electric-motor power demand. At design and near-design loads, however, it has the opposite effect. Widespread application of VFDs, then, might cause an increase in the design power demand of electric utilities, forcing them to administer mandatory consumer power-demand-shedding programs. An increase in design power demand over installed power capacity might lead to other negative consequences, such as electric-utility power outages, consumer productivity losses, and increased environmental pollution. This article demonstrates how automatic switchover from VFD control mode to VFD-bypass control mode and back can help to mitigate, if not eliminate, these negative impacts."

Navigating Energy Code Compliance For Metal Buildings

Insulation Outlook, Feb. 2016, by Hal Robbins.
http://www.insulationoutlook.com/io/article.cfm?id=IO160203

"Understanding and complying with today’s evolving energy codes and standards presents unique challenges for architects, designers, and builders of pre-engineered metal buildings.... In an effort to navigate (and hopefully simplify) energy code compliance, the intent of this article is to help specifiers determine code adoption status using web-based tools and to review various high R-Value/Low U-Factor insulation systems currently available for metal building roofs and walls that provide code compliant options."
