Manufacturing Matters: 5/11 Weekly Wrap Up

The New York Times reports that manufacturing is “one of the few bright spot of the recovery, restoring 489,000 jobs since the beginning of 2010.” The article also describes geographic distinctions in growth, with half of the most manufacturing-specialized metropolitans now located in the Midwest.

Plastics News reports that in California a controversial pro-plastics lesson has been removed from a new statewide curriculum on the environment. After the EPA looked over the proposed curriculum, the section titled “Advantages of Plastic Shopping Bags” was replaced with recycling statistics in an 11^th grade textbook.

Smart Grids: Bringing Utility Systems into the 21st Century.

What is a smart grid?
Just as smart phones have evolved into multi-purpose devices that support a wide range of applications, smart grids have become a way to computerize the electric utility grid and better manage the increasing energy needs of 21^st century consumers.

The “grid” encompasses all the networks that carry electricity from the plant where it is generated to the homes and office buildings where we consume it. Smartgrid.gov refers to our current grid as an “aging infrastructure” set up to handle only simple energy demands.

For the past 100 years, utility workers have had to go out to gather much of the data needed to provide electricity — reading meters, looking for broken equipment, measuring voltage, and so on. And most of the devices utilities use to deliver and manage electricity rely on manual or analog systems. Now, the electricity industry is taking great strides to modernize the process.

A smart grid system digitizes data collection and also acts on information about consumer behavior — similar to the way Google learns your online searching habits and Netflix knows your movie preferences. Each device on the network has hi-tech sensors to gather data and automation technology that allows the utility company to adjust and control each individual device or millions of devices from a central location.

In addition, a smart grid system can

Detect faults and isolate outages
Restore electricity quickly and strategically after power disturbances
Reduce management costs for utilities, lowering power costs for consumers
Reduce peak demand, which will also help lower electricity rates
Enable active participation by consumers in demand response
Integrate large-scale renewable energy systems
Integrate customer-owner power generation systems
Operate resiliently against physical and cyber attack

Who supports the smart grid?
In 2007, Congress passes the Energy Independence and Security Act, which supports the DOE in leading and coordinating a national grid system. Such a system would involve upgrading the current system or replacing it altogether. Smartgrid.gov advocates that a modern grid be constructed “from the bottom up to handle the groundswell of digital and computerized equipment and technology dependent on it.”

In 2009, the Obama administration allocated $3.4 billion in grants as part of a stimulus package to help utilities develop and implement technologies such as smart meters, digital transformers, and automated power monitoring and management systems.

We have seen smart grids deployed on a smaller scale in cities like Austin (2003) and Boulder (2008), and several areas in Europe and Canada are currently working towards large-scale smart grid systems.

Smart grids are designed to give consumers more control over their energy use. Imagine monitoring and managing electricity just as you do your bank account. Smart grids will provide a clear and timely picture of how much electricity you use and when it costs the most to run.

The Evolution of Insulation

As we grow more aware of our environmental impact—and as utility bills grow more costly—energy efficiency becomes a central concern in construction projects and building updates. LEED certifications set efficient buildings apart from the rest. Pink attic insulation doesn’t quite cut it anymore.

Natural Insulation
Although it’s a hot topic now, energy efficiency—insulation in particular—is nothing new. Since the beginning of time, the Earth and its inhabitants have found remarkable ways to regulate temperature. Atmospheric gases gather in the ozone layer, water surrounds land, mammals grow fur and store body fat, birds are born with feathers, and early on, humans discovered heat-trapping material like wool.

We have always put extra effort into shielding ourselves from the elements. Early humans built their homes out of natural insulators like grass, leaves, straw, mud, ice, and mountainsides. And landscaping wasn’t always about aesthetics—trees planted near houses provided precious shade and insulation.

While keeping extreme temperatures out, people also came up with ways to generate heat within. Some buildings in the Roman Empire and ancient Korea used empty spaces in floors and walls to conduct air heated by furnaces. By 1700, Russian engineers began developing water-based systems to circulate heat.

Synthetic Insulation
With the advent of modern heating systems came the need for better insulators. After all, gas and electric systems don’t come cheap like heat from a wood-burning furnace, and they create conditions that need to be regulated in order to work properly.

In 1930, Dale Kleist, a researcher at the Owens-Illinois Glass Company, made one of those lucky mistakes that so often leads to a monumental discovery. While trying to seal two plates of glass together, he accidentally shredded the glass into tiny fibers with a high-pressure air hose. Thus, fiberglass was born and soon found its most common form in blanket insulation.

Meanwhile, manufacturers began to realize the benefit of insulating not just their buildings but their heat sources as well. This helped protect workers and equipment, save energy, and improve overall efficiency.

Custom Insulation
We’ve come a long way since adobe huts and igloos. Today, engineers use R-values (the measure of thermal resistance) to quantify and compare the insulating capability of different materials. In this way, they can combine the most effective insulators and create premium insulation.

Opportunities for Greater Efficiency in Custom Molding

As more and more manufacturers see significant energy savings after insulating their machines, insulation jackets are becoming priority number one in many energy management strategies.

UniTherm has been supplying insulation jackets in the plastics industry for over 30 years, and with each new product and custom service, UniTherm strives to address a specific processing need. With this innovative mentality, UniTherm can provide opportunities for greater efficiency, as it has with its new product called QuickCool.

QuickCool is an insulation jacket with an additional feature—it is designed to open easily so that machines can quickly cool as they are prepared for different processes. QuickCool wraps completely around the barrel and insulates as well as UniTherm’s other jackets, but it has high-temperature straps on the inside to hold it in place while the top flap opens to release heat when necessary. Otherwise, the top flap velcros tightly to the rest of the jacket to keep machines working at high efficiency with minimal heat loss. This way, barrels and heater bands are always easily accessible without having to remove the entire jacket, and machines can reach and maintain different desired temperatures as needed.

QuickCool closed to insulate

QuickCool open to release heat

Barbara Arnold-Feret, custom molding expert and new addition to UniTherm’s sales team, calls QuickCool a “flexibility enhancer.” QuickCool, she explains, “offers all the advantages of insulation along with the ability to change temperatures quickly. It allows great flexibility for molders looking to cool their machines for whatever reason, including material changes.” No longer do custom molders need to worry about insulation encumbering their access to the machines or their ability to switch processes involving different materials. “It is especially convenient when working with polyolefins and perfect for molders that make a little of everything,” says Barbara.

In fact, a custom molder with 3,000 molds running short runs with PolyPro and ABS installed QuickCool blankets on its machines and found that the product allowed them to cool from 550˚F to 350˚F in the time it took to change the mold.

UniTherm has been supplying insulation for over 30 years, and the Research and Development team continues to explore new energy-efficient solutions. They are excited to offer a product that will not only save energy but also adapt to the alternating processes in custom molding.

How to Conduct an Energy Study at your Facility

“You can’t manage what you don’t measure.”

It’s true. We offer a lot of general advice about how manufactures can save energy, and we have a great deal of data showing the results of different energy-saving strategies, but each facility operates differently, and in most cases, energy plans must be tailored to fit the facility. Your measurements govern how you manage and guide your strategic course of action.

That’s why DIY approaches are so beneficial for facility owners and managers—they offer adaptable tools that bring you closer to remedying a problem or operating more efficiently.

We can all agree that energy prices are high and machines consume huge amounts of energy, ergo operating machines is an enormous expense (the third largest, behind materials and labor, to be exact). But let’s take a step back. Before you seek out solutions, it’s important to know exactly how much energy the machines in your facility are consuming.

That’s where the Power Sight PS 2500 comes in to play. Experts at your energy company use this handheld meter to measure and log energy output. But if you don’t want to hire a professional, you can easily do it yourself. Here’s how:

Connect the PS2500 to your computer via Bluetooth. This will allow you connect wirelessly, install Power Sight software, and sync the PS2500 with your computer.
Check the settings in the electrical panel. Identify the relays, the power source supplying them, and the direction of power to ensure accurate measurements.
Connect the PS2500 to the machine using the voltage, amperage, and natural clamps. When all three are attached, the machine will connect to the computer.
Run the test. Initiate the test using the keys on the PS2500. Data logging parameters can be set within the software. The meter will measure and log energy output until you discontinue the study. You can use the Remote Control option and control the meter completely from your computer.
Create a report. Save the data uploaded your computer, and the Power Sight software will generate a report. From there you can compare, summarize or compile the data as you like.

How to Join the Better Buildings, Better Plants Challenge

Going green. Saving energy. Encouraging efficiency. Reducing carbon footprints. Promoting eco-friendly practices. Being environmentally conscious. Conserving resources. It goes by many names, but the social movement is undeniable.

I remember seeing for the first time the trendy “Save the Planet” tees cropping up in clothing lines of popular retail stores. Years later, it turns out that going green more than a fashion trend. It is a compilation of personal and political choices that continues to build momentum worldwide.

We can see big impacts, too, when we look at the sum of our efforts. That’s why government and corporate entities promote going green, leading by example and initiating challenges to get others involved.

Better Buildings, Better Plants Challenge

Last year, President Obama and former President Clinton issued the Better Buildings Challenge and extended the challenge to industrial plants for an even greater impact. Because buildings consume about 20% of all the energy used in the US, the initiative’s long-term goals include

Updating American buildings to make them 20% more energy efficient
Saving American businesses nearly $40 million in energy costs

With the help of energy efficiency products, services, technologies, and partnerships, several industrial partners have stepped up to the challenge—3M has 78 participating plants, Alcoa has 30, Nissan has 3, and GE has 125 million sq. ft. of plant space (to name a few).

But you don’t have to be a big name with copious plant space to make a difference. Think of it this way—as a little guy, your carbon footprint is already smaller so you don’t have to make such extravagant changes. Every little bit counts.

To join the Better Buildings, Better Plants Challenge

Assess your building portfolio to determine energy efficiency opportunities and publicly pledge an organization-wide energy savings goal for the next 2-5 years.
Announce and initiate a showcase project on 1 facility (retrofit, retro commissioning) and develop an organization-wide plan to achieve your energy savings goal.
Share your experiences with energy efficiency solutions, your organization-wide energy savings, and the energy performance at individual facilities for recognition.

In return for your commitment, the Department of Energy agrees to support you via expert technical assistance, connect you to a network of allies, and provide you with national recognition. Win-win-win.

What are you doing to green your building? The Better Buildings Challenge is just one way you can contribute to the social movement. Incentives are abundant, and the payoffs reach far and wide. For starters, you can insulate your equipment to conserve energy and maximize efficiency, and when you start seeing the savings, you can move on to other areas like HVAC and lighting for a complete energy-efficient overhaul.

Untapped Energy Savings in Process Heating

Almost all industrial facilities use some form of process heating, but most companies, even those with strong energy management programs, often overlook the huge potential for energy savings in hot industrial processes.

Industrial facilities make up nearly one-third of the nation’s total energy consumption and according to a recent Department of Energy study, plants with hot processes stand to save 5 – 20% on energy costs by implementing process heating system best practices.

Taking proper steps to reduce heat loss from process equipment, tanks hoses or pipes that reach temperatures of 250°F can significantly reduce energy costs in multiple ways. In many processes, temperatures often exceed 500°F requiring significant amounts of energy to maintain process temperatures and cool a facility’s ambient air temperature. For manufacturers that continuously operate production equipment, the potential energy savings increase exponentially.

The easiest and lowest-cost method of of eliminating energy waste in hot industrial processes lies in insulating process equipment, hoses and hot air ducting. UniVest systems by UniTherm are custom insulation jackets designed to snugly fit equipment and direct heat where it belongs – inside high temperature equipment. [Read more…]

A Quick Guide to Energy Management Software

If you’ve picked up any industrial trade journal or browsed the business section of the news for energy related topics, you’ve probably read about energy management software of some type. Everyone seems to agree that energy management software is the next big thing, but how will such systems actually help your business?

Energy management software generally provides options for evaluating effectiveness and ROI of efficiency projects or for measuring, tracking and controlling energy consumption to eliminate waste.

Software for Energy Efficiency Projects

With so many options to choose from, determining which energy efficiency projects to implement might seem a difficult task for any industrial facility. Employees tasked with reducing energy costs often have limited budgets and must prioritize new projects and plan for future implementation.

Through the Energy Efficiency & Renewable Energy (EERE) division the U.S. Department of Energy offers free calculators and software tools that allow you to analyze opportunities to reduce energy costs and help you calculate possible energy savings gained from energy efficiency projects. These tools help calculate the potential return on investment or paybacks for projects, like high temperature insulation jackets, allowing you to purchase the most cost-effective projects first and achieve the greatest amount of energy savings.

Beyond software tools, the EERE also provides a variety of training courses, seminars and webinars for those interested in reducing energy costs with software. Segmented by industry, these resources offer significant insight into options available for you to reduce energy costs.

Energy Management Systems

Available as basic software that controls lighting systems or more complex systems that measure, analyze and control energy consumption, efficiency software offers many custom options for improving efficiency. Sophisticated software systems monitor every aspect of energy consumption and manufacturing emissions, store data that you can use to pinpoint energy waste and send web or cell phone alerts notifying you of any issues.

With such a large range of software options available, determining which services you need isn’t always easy. According to a recent report by business research leader Verdantix, the best method for choosing appropriate management software lies in implementing readily available, free software, choosing a reputable software provider, and clearly outlining your needs prior to the sales process.

What systems are you currently using to monitor your energy usage?
