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.

International Standards for Energy Management: How ISO 50001 Can Help Companies of All Kinds

“Individual organizations cannot control energy prices, government policies, or the global economy. But they can improve the way they manage energy.” –ISO Secretary-General Rob Steele

Energy is one of the largest controllable expenses of your plant, or of any building for that matter. And luckily, as more and more building owners realize remarkable ROI in energy-saving strategies, the amount of related information continues to grow.

In fact, a quick Google search for energy management returns about 54,800,000 results, which gives us about 78 pages to wade through. Of course, no one has time for that, so we usually just collect tidbits of advice we hear about going green and put them to use as best we can.

For example, at home I know to keep the thermostat under 68° in the winter and over 72° in the summer for better energy savings. I know to run the dishwasher only when it’s full to maximize water use. I know to open the shades during the day to let in natural light. I’m sure you’ve heard similar rules of thumb.

So we’ve got the basics down, but managing energy in an entire plant requires a bit more forethought than simply turning off the lights when we leave the house.

download avaiable at iso.org

Fortunately, the International Organization for Standardization (ISO) launched an energy management standard last summer. According to ISO, the energy standard—ISO 50001—will provide industrial plants, commercial, businesses, government facilities, and entire organizations with “access to a single, harmonized standard for implementation across the organization with a logical and consistent methodology for identifying and implementing improvements.”

Twenty-six US facilities, including 3M, Cook Composites, Dow Chemical, Nissan, and Volvo, participated in ISO 50001 pilot programs. In addition, the Department of Energy endorses ISO 50001 as a “proven approach for US industrial commercial facilities to plan, manage, measure, and continually improve energy performance.”

Companies implement these energy standards to reduce their energy consumption and environmental footprint, but they can become ISO 50001 certified as well. On March 8^th of this year, Volvo’s Dublin plant was the first US facility to achieve certification. This third-party verification can afford companies a competitive edge and greater confidence in their supply chain.

For those that utilize it, the energy standard will be hugely helpful as it takes the guesswork out of energy management. Instead of the trial and error strategy I use at home, haphazardly turning the thermostat up or down, ISO 50001 provides an explicit framework applicable in any company—public or private, large or small. Companies worldwide can now adopt best practices in energy management.

Have you begun working towards your ISO 50001 certification? What other energy management tools—software, audits, etc.—do you use at your facility? If you’re kicking off a new energy management program or you’re working to keep your energy output in check, get a customized energy report today.

The New Heating System that will Radically Change the Way You Heat

Imagine a world where heat is always consistent, quick, efficient, and safe. Imagine a heating system that is 70% more efficient than the way you heat now and still safe enough to touch with bare hands. Is this some distant dream, or have we truly arrived at the future of heat technology?

At NPE 2012, UniTherm International introduced its latest product—RapidTherm, an innovative heat solution designed for plastics machinery. UniTherm has been manufacturing insulation jackets for over 20 years, but this new jacket is truly the first of its kind.

RapidTherm is unique in that it combines heating elements and insulation in one easy to use, easy to service unit. The 1-piece, removable insulation jacket includes a built-in thermal vein powerful enough to heat an entire machine. Not only is the thermal vein a more efficient heat source than traditional heater bands, but because it’s encased in high temperature insulation, it saves energy by eliminating excess heat loss.

In tests, the RapidTherm jacket heated barrels twice as fast (cutting start up time in half) and dramatically decreased energy usage. On production equipment, the new heating system

Decreased start-up time by 50%,
Cut energy usage by 70%
Kept the outer surface cool enough to comply with OSHA hot surface standards
Increased worker safety
Cut maintenance time and costs
Eliminated hot spots on the barrel heating profile
Eliminated the need for a barrel shroud

RapidTherm has proven itself as an efficient heating system and promises to liberate processors from the hassle of heater bands. “For years, we’ve known there has to be a better, more efficient way to heat machines,” explains UniTherm president Dan Sherrill. However, previous alternatives to heater bands have been plagued with problems. NPE 2012 was the perfect opportunity to unveil the new heating system, and RapidTherm sparked interest among processors looking to save time and money at their machines. It seems RapidTherm will be the solution that finally puts the heater band headache to rest.

It’s certainly an exciting time for new technology in engineering and manufacturing. Subscribe to our blog for more innovative ideas and industry updates.

Less is More and Lean is Better: Managing Inventory in Manufacturing

The concept of lean manufacturing is simple. Much like a diet for your facility, the goal is to reduce your waste (like you would your waist) for healthier operations. It’s not about starving your business because, let’s face it, you can’t run a marathon or outlast competitors without proper sustenance. Lean strategies are about taking in only what you need and making the most of it—kind of like politely pushing away a plate of food when you’re full rather than stockpiling calories for a later date.

Now I know by March many of our weight loss resolutions have run their short-lived and often unfulfilled courses, but it’s always a good time of year to take on a new style of inventory management.

How manufacturers manage inventory
Many manufacturers produce products in large runs, even when the demand for that product is low. Products are stored or kept in inventory until they are eventually sold, which often leads the manufacturer to overspend on storage. When production runs are too large, manufacturers run the risk of filling inventory with products that might become outdated and remain unsold.

Why lean strategies are more efficient
A crucial component of lean manufacturing involves controlling inventory by reducing excess production. This means implementing a system for monitoring inventory and producing products in smaller runs rather than keeping excess inventory in storage.

Wait, it takes time and money to modify the way you manage inventory and thin out the production line. But just like dropping a few pounds, the payoff doesn’t occur overnight. Soon enough, the savings from storage costs and unnecessary waste will find their way to the bottom line. It’s well worth the change—just ask Toyota, Boeing, Caterpillar, and Xerox.

Not only will lean strategies lower your overhead costs, but they will also challenge your employees to think critically to improve existing procedures. No reason to keep things the way they are just because—hopefully your facility is always on the look out for more efficient ways to operate. Plus, you won’t have to feel that little pang of guilt as you throw away perfectly good products because of bad timing.

See it to Believe it: The Benefits of Thermal Imaging

When thinking about energy output in a manufacturing plant, it’s natural to go to the lights and the HVAC. This makes sense since these are typically the top energy expenditures, but it’s a plant’s machines that devour more energy than all other utilities combined. That’s right, machines consume about 60% of total energy costs. How do we know this? Well, government agencies and other entities provide plenty of studies and statistics for us to read over, but why not see the energy output for yourself?

Thermography is more than fancy spy gear for secret agents to expose hidden enemies—it has a wide range of commercial and industrial applications for those of us in the real world as well. For manufacturers, thermal imaging allows you to visually track the amount and consistency of heat emitted by your equipment. With a thermal camera, you can compare the output of the different heat sources (even those not-so-easy-to-access heat sources) in your facility from a comfortable distance. This way you can find defects in shafts and pipes and locate deteriorating components before they fail.

Equipped with a thermal picture (a thermogram, in case you want to sound technical), you can easily spot the energy hogs highlighted in yellow, orange, and red—so you know exactly what areas to target as you take steps to reduce your energy costs.

Thermal Imaging

Immediately you’ll see your machines light up hot—as they should, that’s how they work. But most likely they don’t need to be operating that hot or emitting as much heat as they do.

The good news? Machines represent your greatest opportunity to conserve energy. Instead of idling, consider powering down equipment during non-peak hours, make sure motors are working as efficiently as possible, and insulate, insulate, insulate. The ROI is remarkable—insulation saves an average of $164 per machine per month. See what thermal imaging reveals so you can start saving.

Why Induction Heat is Super Efficient

Faster than a speeding bullet! More powerful than a locomotive! It’s not up in the sky, it’s…unbelievably efficient induction heat technology!

Ok, maybe I sound a little fanatical, but if you’ve never seen induction heaters in action, I seriously recommended you watch some induction heating demos. These videos will blow your mind. You’ll see metal wires melt, aluminum cans explode, and ice cubes set ablaze—before they even have a chance to melt!

What is induction heat?
Induction is a heating method, but unlike conduction or convection heating methods, it doesn’t require a transfer medium. The inductor itself can be a simple-looking strip of coiled metal (precisely designed to optimize the magnetic field and alternating currents), and the magic is, the inductor never touches what it’s heating, and it never gets too hot to handle with bare hands. I won’t get into the physics of it all, but if you’re interested in how induction heating works, see inductionatmostpheres.com. Basically, induction heat uses radio frequencies, and that’s how it can work sans transfer medium—heat is “induced” by the circulating electrical currents.

The shift toward lean manufacturing and the emphasis on better quality control have led to the rebirth of induction technology and the development of precisely controlled, solid-state induction power supplies.

How can induction heat benefit manufacturers?
For most industrial applications, induction heating offers significant advantages over traditional heating methods—the fast, accurate, and consistent heat transfer reduces energy consumption and creates a safer working environment.

Companies like Ford, John Deere, GM, Cat, Volkswagen, and BMW have already implemented induction heat into their manufacturing processes. Most manufacturers that switch over to induction technology report a decrease in their utility bills. Why is this? Because induction is a highly efficient means of heating that requires less energy to do the same job as, say, a heater band, which is constantly losing energy and reheating.

In fact, uninsulated heater bands are only 30-70% efficient and have a limited lifespan because they must stay hot to operate. Induction heaters, on the other hand, are typically 95% efficient and don’t emit excess energy. Even better, insulated induction heaters can reduce ambient energy loss by 98%.

How can you use induction heat to make your manufacturing process more efficient? If you haven’t already, start thinking about this innovative heating method, and stay tuned for the latest in energy efficient technology.

The Best Ways for Manufacturers to Save Energy: Surveying the Site

Who doesn’t want to save energy? Now more than ever, we are all looking for ways to cut back—we turn down the lights and turn off the thermostat, we run the dishwasher less and take shorter showers—hoping to save some money on the monthly energy bill.

But when you run a large manufacturing plant, the task of saving energy may be a bit more daunting. Before you can start conserving energy, you have to know where the most energy is being consumed and what the best opportunities are for reducing high-energy output.

Knowledge is power, so we’ve put together a simple site survey checklist to help managers get well acquainted with their plant’s energy output. According to the Energy in Plastics Good Practice Guide, you should carry out an initial survey immediately because “if energy is being wasted, it is costing money.” A 20% cut in energy costs can equal the same bottom line benefit as a 5% increase in sales.

It’s also a good idea to take an unannounced walk around the site at about mid-shift to see how things are running during normal working hours.

What to look for during an initial walk through
Keep a close eye on the machines. Machines consume about 60% of energy costs. Yikes. But think of it this way—here lies your greatest opportunity for energy savings.

As you survey the site, keep these questions in mind:

Which areas have the largest energy load? Look for the largest machines; they will have the largest motors and consume the most energy.
Which motors are running? Would smaller motors be more efficient? Could they be turned off during non-peak hours?
Are machines well insulated? Is the insulation in good condition?
Are hot and cold pipes insulated? Is the insulation in good condition?
Which cooling water pumps and vacuum pumps are running?
Does compressed air pressure need to be so high, or the vacuum so low? Can you hear steam and compressed air leaks?
Are lights and machine heaters left on? What is running during lunch breaks and and after working hours?

With a better understanding of where unnecessary energy output occurs, you can now take productive steps to decrease it. Don’t wait—conduct your site survey today to start saving energy and increase that bottom line!
