Innovative Blow Molds Reduce Compressed Air Pressure in PET Blow Molding

Compressed Air Best Practices, Mar. 2016, by Vincent Duvernois,  Stephane Larcade, and Jean Pilnard.

"Technological trends in plastics manufacturing are driving the costs of production down. In industrial PET blow molding specifically, two innovative techniques have had major impacts over the last 15 years: “light weighting” the plastic bottles, and recirculating high-pressure compressed air. Both have helped to improve the energy efficiency of PET blow molding by reducing compressed air requirements dramatically."

Electric Motor Efficiencies and VFD Compatibility

ASHRAE Journal, Feb. 2016, by David A. John.

"When consulting engineers select and specify fans for HVAC systems, they often specify that the motor for a fan should be a premium efficiency motor. this is critical because most variable frequency drives (VDs) require a premium efficiency motor."

Combined Heat and Power (CHP) Technical Potential in the United States

U.S. Department of Energy, Advanced Manufacturing Office, Mar. 2016.

"This study provides data on the technical potential in industrial facilities and commercial buildings for “topping cycle” CHP, waste heat to power CHP (WHP CHP), and district energy CHP in the U.S. The report provides valuable data on the technical potential for CHP in strategic energy planning and energy efficiency program design. The study shows that within the U.S. there is estimated to be more than 240GW of technical potential at over 291,000 sites. Data is provided nationally by CHP system size range, facility type, and state."

Engine Block Heaters: Quick Starts for Standby Power

Forester Daily News, Mar. 14, 2016, by Penelope B. Grenoble.

"...whether you call them block heaters, water jacket heaters, or engine preheaters, they’re essential to getting diesel-fueled gen sets up and running at full power in the 10 seconds that are standard for emergency power applications."

Learning from Islands: Renewable Transitions for Mines, Industrial Facilities, and the Military

Rocky Mountain Institute Outlet, Mar. 11, 2016, by Kaitlyn Butler and Kate Hawley.

"What do mines, industrial facilities, and the military all have in common? They all have a need for reliable electricity in remote locations. It turns out these places and others can learn a lot from islands. Rocky Mountain Institute and Carbon War Room’s recent microgrid casebook, Renewable Microgrids: Profiles from Islands and Remote Communities Across the Globe, explores 10 examples of islands and remote communities from around the world that have transitioned from 100 percent oil-based electricity systems to high-penetration renewable microgrids."

Q&A: What to Know About the New DOE Pump Energy Efficiency Rule

Flow Control, Mar. 3, 2016, by Michael Michaud and Peter Gaydon.
http://www.flowcontrolnetwork.com/qa-what-to-know-about-the-new-doe-pump-energy-efficiency-rule

"To get an overview of the U.S. Department of Energy (DOE) Pump Energy Efficiency Rule, Flow Control talked with Michael Michaud, executive director of the Hydraulic Institute (HI), and Peter Gaydon, its director of technical affairs. HI uses a pump systems approach to developing industry standards, providing knowledge and resources, educating the marketplace, and advocating for the industry."

Using Insulating Firebricks to Maximize Energy Savings in Iron and Steel Applications

Insulation Outlook, Jan. 2016, by Steve Chernack and Chris Johnson.
http://www.insulationoutlook.com/io/article.cfm?id=IO160101

"Engineering design and the lining materials chosen are key factors in controlling the efficiency and energy usage of equipment used in iron and steel applications. Thus, it is critical that industrial designers understand the advantages and disadvantages of the materials they choose. One option for lining material is insulating firebricks (IFBs), which can minimize energy losses. Recent studies conducted on IFBs using the 3 most common manufacturing methods—cast, slinger, and extrusion—show that the cast process offers the lowest thermal conductivity and provides the greatest energy savings."

Air Barriers for Metal Buildings

Insulation Outlook, Feb. 2016, by William Beals.
http://www.insulationoutlook.com/io/article.cfm?id=IO160204

"Air barriers have been discussed and used in different ways since the 1930s. The purpose of an air barrier is to limit uncontrolled air leakage into and out of the building’s envelope. A building’s envelope is defined as roof, wall, and floor area that encloses a heated or cooled area. Uncontrolled leakage will result in increased energy usage due to the heat or cooling lost."

Select the Best VFD for Your Application

"According to the technical experts at Mitsubishi Electric Automation, Vernon Hills, IL, there are several factors to consider when selecting variable-frequency drives (VFDs)."

Calculate the True Cost of Unreliability

Maintenance Technology, Feb. 2016, by Al Poling.
http://www.maintenancetechnology.com/2016/02/calculate-the-true-cost-of-unreliability/

"Although experts have espoused the virtues of equipment reliability for decades, countless manufacturing operations still suffer significant and unnecessary downtime due to equipment failure. Apparently these manufacturers haven’t bought into the benefits of failure-free operation. What will it take to get them to accept the time-proven benefits of reliability? Perhaps they will never be convinced by examples of other manufacturing operations, believing that they are somehow unique."
