Sometimes we come across a bit of information that leads to a discovery about something we have long taken for granted. This new learning allows us a better understanding of how things function in a world that’s increasingly driven by technology.

A routine supermarket visit to purchase fruits, vegetables, meats and dairy items can yield one of those “ah hah” moments, especially when you look deeper. Take fruits and vegetables. There is such a wide selection - especially those that are on the shelf in the off-season! Where did they come from? California, Peru, New Zealand? How did they arrive at the peak of freshness? These are intriguing questions that offer “food” for thought.

In my years of experience within the transport refrigeration market, I appreciate the know-how, the people, products and technology that allows the movement of fresh food over long distances through what we call the food chain. This chain begins at the source, the point at where the food is picked and ends at your local grocery store. No matter what the cargo, the ‘chain’ of temperature control must remain unbroken over hundreds or thousands of miles to assure quality, maximize freshness and deliver value.

For the most part, refrigerated cargo is transported in either an ocean-going container or an over-the-road trailer/truck body with an integrated refrigeration or “Reefer” unit. These state-of-the-art machines are capable of maintaining precise temperature control throughout their interiors. They’re super-efficient because they balance temperature, air flow, and reliability.

RefridgeratedTruck











On the surface, you’d think that temperature control is the most important – and you would be right. Almost. With sophisticated microprocessor controls, reefer units are designed to control cargo temperatures to within +/- ½ degree of set-point for extended periods of time over a wide variety of ambient conditions. However, temperature control cannot happen without precise air flow that moves air efficiently and effectively in every nook and cranny of the trailer to preserve those delicate fruits and leafy veggies we love. To protect the supermarket’s investment in its precious produce, the whole system must perform reliably over years of service.

Since the whole process is powered by some form of renewable energy or fossil fuel, it also must operate at maximum efficiency.

Our fans provide the critical ventilation that boosts the food-preserving performance of commercial transport units’ temperature controls. Designed to survive climate extremes and road shock, they allow precise delivery of air reliably and efficiently. Our food transport customers depend upon ebm-papst fans’ ability to meet their containers’ and trucks aerodynamic, electrical, and operational requirements day after day, month after month, year after year without fail.

The next time you purchase those delicious Chilean grapes or Mexican mangos in January, remember the combination of transport components and controls it took to deliver them across the food chain and unblemished to your table. Now that’s food for thought!

The sound of silence for air handling equipment

Compact, efficient FlowGrid air-inlet grill from ebm-papst  significantly reduces noise spectrum for
axial and centrifugal fans

FlowGrid 250pxWhether it’s heat pumps in the home, condensers in supermarket refrigerators or ventilation systems on the production floor, FlowGrid, the innovative patent-pending air-inlet grill from ebm-papst, is dramatically reducing noise levels for fans installed within limited-space air moving equipment.

What our award winning AxiTop diffuser does on the pressure side (outlet)
of the fan, FlowGrid does on the suction side (inlet). Easily mounted to applications with ebm-papst fans and backward curved impellers, its open grill design straightens airflow to minimize turbulence before the air hits the axial or centrifugal impeller blades. FlowGrid is ideal for fans installed within flat and central air handling units, air purifiers and heat pumps with centrifugal fans, or air-water heat pumps, condensers and V-shaped condensers
with axial fans.

FlowGrid2 500px

“FlowGrid is the result of our extensive airflow testing for inlet conditions with a wide variety of customers’ axial and centrifugal fans across dozens of applications,” said George Riker, business development. “By improving the aerodynamic conditions external to the fan, FlowGrid reduces the adverse effects of these inlet conditions and
minimizes noise.”

Here’s how noise happens within a fan and how FlowGrid corrects it:

  1. When the walls of a device such as an air handler, heat exchanger or heat pump are different distances from the fan, powerful vortices combine in the narrowest areas to form so-called ‘vortex strings.’

  2. These turbulences then hit the rotating blades of the fan, generating noise – specifically a broadband noise and additional narrowband, tonal frequency components, known as propeller noise or tonal noise.

  3. Mounted on the air intake side of the fan, the FlowGrid weakens these ‘vortex strings’ as they flow through the device.

  4. This reduces sound pressure across the entire sound frequency range and especially in the low frequency tonal range.

Apart from reducing overall sound pressure, the most drastic reduction is in low-frequency blade-passing noise (the sum of the fan speed and the number of blades) caused by blades cutting through turbulence within small space applications such as heat exchangers. The FlowGrid grill has been proven in certain applications to reduce overall sound pressure levels by as much as 3.9 dB(A), and these blade passing frequencies by up to 16 decibels.

FlowGrid2 250pxWith FlowGrid, ebm-papst is making a clear contribution to passive noise reduction – a big part of our GreenTech philosophy. It can help manufacturers and ventilation specifiers comply with noise regulations and improve the environment for employees who work near ventilation equipment. The innovative air-intake grills, which require less acoustic insulation, work with both axial and centrifugal fans without reducing their performance. Using them can help to reduce or entirely avoid the use of cost-intensive, active noise-reduction measures.

Ergonomics for the manufacturing floor – keeping it healthy and safe

Posted on Thu, Jan 16, 2014
BrianLadegard 110x145
By Brian Ladegard- Director of Operations

In manufacturing, we have to anticipate and react to several challenges that arise when building
our products – product weight and required fastener torque are two of the most common.

Product Weight
Our products have become increasingly larger over the years, as our product range has expanded and our EC motors began to proliferate. We now work with parts that are much heavier than previous generations.
To avoid unScizzor Jacknecessary injuries (such as back strain or pulled muscles) from product lifting, we researched, specified and installed many lift assist devices. These devices range from the simplest form of a Scissor Jack, whereby the product pallet can be raised off the floor to a more comfortable 32” working height, to more elaborate larger crane systems.

Generally, we use two main types of cranes – overhead bridge cranes and freestanding jib cranes. Overhead describe the imageBridge Cranes allow for mechanically assisted part lifting
and then movement from station to station in a work cell. Typically, this type of crane assists in moving product through 3-5 stations in succession. Freestanding Jib Cranes perform the same assisted lifting – but only do this in a small circular area around their base. Typically, we use jib cranes to pull parts out of boxes, put parts into boxes, or assist with lifting in a single work space. Both are designed to keep operators from becoming fatigued over a full shift of work.

Required Fastener Torque
The other related challenge is fastener torque. Along with our product sizes – the fasteners we use have also grown overtime. Generally, fastener torque is proportional to the size of the fastener. Torque is the twisting force required to install a specific fastener so that it tightens the mechanical joint and keeps it from separating.
The issue with torque is one of physics – for every force there is an equal and opposite force. So, when we use a pneumatic or electric screwdriver to apply this force, there is an equal and opposite reverse force felt by the person (or device) that is holding the screwdriver.  This is called a “torque reaction” or “break back torque”. If left unchecked, it can cause muscle damage, aches and soreness to operator wrists. So, whenever we use devices with higher torque values we employ an “ergo arm” or a “counterbalanced arm”. These arms are supplied by the makers of the screwdrivers and are designed to allow for free movement of the screw gun, while eliminating break back torque on the operator’s wrists. Typically, they also balance the physical weight of the tool – so operators can work for long periods using this tool with comfort.

How to avoid HVAC motor failure

Posted on Thu, Jan 09, 2014
describe the image
by Matt Menard, Market Manager - Air Conditioning

In the world of HVAC, motors move conditioned air throughout the system. When a motor fails, cooling or heating ceases, leaving occupants of that building uncomfortable. The motor can be replaced relatively quickly with an experienced technician. However, diagnosing what caused the failure is difficult, time consuming and often ignored.

Motor failure is a major headache that can cost building owners significant money. With limited budgets and resources, implementing a preventative maintenance program on motors to minimize failures can be difficult for most. So what is the solution?

HVAC System 400pxThe December 9 issue of ACHR News discusses causes and prevention of motor failure. All of these types of failure can be avoided by choosing external rotor EC motor technology, such as is utilized in ebm-papst’s product line, to boost reliability and efficiency.

  1. Belt — Belt tension is critical in avoiding vibrations between the fan wheel and motor. Belts tend to stretch throughout their lifetime, so technicians tend to over tighten during replacement. A belt that is too tight overloads the motor and shortens the lifespan. ebm-papst external rotor motors do not use belts—the fan wheel is mounted directly to the motor rotor.

  2. Overheating — This is the most common cause of failure. Dirt buildup on the fan wheel and poorly designed/installed ductwork causes additional strain on the motor resulting in overheating and a shortened lifespan. ebm-papst EC motors have temperature sensors built into the internal electronics package that act as a safety device in the case of overheating.

  3. Electrical Fluting — When utilizing a Variable Frequency Drive (VFD) for speed control, users can experience a phenomenon called electrical fluting, which basically equates to a mini-lightning storm that occurs within the motor as voltage and frequency are regulated by the VFD. This ‘storm’ affects the bearings, resulting in premature failure. Electrical fluting is unpredictable and requires additional measures such as shaft grounding kits and ceramic bearings to prevent. ebm-papst EC motors have built-in speed control and do not require a VFD, eliminating the electrical fluting issue.

In addition to eliminating belts, adding temperature sensors and built-in speed control, industry experts such as Jim Connell of AirXChange Inc. believes that ECM fans are more reliable and use less energy than traditional AC motors and drives.  Utilizing external rotor EC motor technology provides not only the most reliable, but most efficient technology available.

Using Computational Fluid Dynamics analysis to reduce our time "back at the drawing board"

Posted on Thu, Nov 21, 2013
Scott Beauchemin
By Scott Beauchemin, Vice President – Engineering

In almost every development process, multiple design iterations are unavoidable. Optimizing an air flow system in a single iteration is rare. In fact, some projects require three or four design loops before the targeted air flow is met. In 2009, ebm-papst Inc. set out to find a way to minimize these steps and thus reduce development costs and get projects to market more quickly. The answer was Computational Fluid Dynamics (CFD) software.

Optimizing air flow systems during development can be challenging. Before ebm-papst introduced CFD to our development process, we would fabricate an initial prototype design using knowledge gained from previous projects. After testing it in the lab, we would compare the results against the air flow, efficiency and noise targets defined at the beginning of the project. In an ideal case, the results from the first prototype would meet or even exceed the targets defined for the project. But typically, the prototype would not exactly meet the targets, and we would move on to a second design. Each new iteration would require engineering time, material costs to fabricate another prototype and lab time to test the new version.  

Using CFD software has reduced the number of design iterations by allowing us to:

  • CFD 200pxRun numerical simulations of the flow field in a system using relatively basic CAD geometry to define the system. The software predicts the air flow through the system, determines the pressure drop, and helps identify problem areas in the flow field. It also looks at heat transfer to determine if critical components are being cooled adequately by the flow through the system.

  • Simulate various designs to determine the optimal one for that specific system. CAD models for each design modification are created.

  • Run those simulations simultaneously, often times after hours so the data is available the next morning. The various design options can be directly compared to determine which characteristics provide the best results.

CFD simulations don’t eliminate the need for experimental data. We still must build and test a prototype in the lab to verify that it meets the design targets. And we still use our knowledge from previous projects – but now, a characteristic can be simulated in the new system to see if it is beneficial. The simulations allow us to quickly narrow in on an optimized design.

The addition of CFD analysis to our capabilities has been a tremendous asset, and is just another example of how ebm-papst is constantly investigating and innovating to offer more efficient processes and solutions to our customers. To learn more, contact sales@us.ebmpapst.com.

Tools of the High Mix Manufacturer

Posted on Thu, Sep 26, 2013
Brian
By Brian Ladegard, director of operations, ebm-papst Inc.

As a high mix, low volume (HMLV) manufacturer, ebm-papst Inc. produces more than 700 unique engineered-to-order products every year for a wide array of market applications at our Farmington, Connecticut facility.

We’re continually evaluating new products’ manufacturability – how can each be produced easily, effectively, and with maximum reliability?  As we serve custom-order requirements, we’re also balancing our plant’s level of automation, organization and manufacturing flow to improve throughput, lower costs and ensure quality.

CNC Machines: A custom shop’s best friend.

Our sheet metal processes — laser cutting, turret punching, press brake bending, hardware insertion, rolling, and single point resistance welding (spot welding) — are set up nicely for low to medium volume production. Our computer numerical controlled (CNC) machines help us rapidly change part geometries through the machine’s software.

For example, our laser cutter allows us to move holes and edges by changing X and Y positions in the machine‘s program code.  If the same part were “hard tooled” (with dedicated die sets and a coil-fed stamping process), these changes would require significant costs and time to re-make sections of tools within each die set.

IMG 0427 resized 600

Our sheet metal methods are appropriate for annual volumes from 5 to 20,000 pieces – representing a good balance between low initial tooling costs, fast time-to-market, and modest piece costs. Sometimes we can make simple investments in punching tools that rapidly reduce our sheet processing times.

Keeping it simple (and flexible)

In our final assembly area, we use simple, generic tools (air screwdrivers, simple wire cutting devices, single-shot pop rivets, and manually initiated testing plans) and develop the final assembly process with minimal need for assembly-specific fixtures.  We’ve set up work cells of 2-3 operators each who divide up that cell’s tasks.  We balance the time for each task, so that no one is left idle as the product moves through assembly. When volumes increase, we utilize dedicated assembly jigs (to assist in standardized label placement, for example) and fixtures to speed the process up.  These are typically developed and purchased when products have consistent “every week” demands.

Just in time’s ally

When volumes ramp up again, we often setup a dedicated work cell space with dedicated tools and KANBAN (“ready floor stock” in bins) component inventories. These dedicated work cells allow us to respond rapidly – as soon as the last component arrives – and begin assembly with very little setup time. 

When to automate. When to go manual.

How does the level of automation at our German facilities compare with automation at our U.S. plant, and why?

Our German operations produce larger quantities that require fewer product variations. This enables them to standardize the way they move parts from one position to the next, utilizing conveyor belts (trolleys) or robotic arms.

In comparison, our U.S. facility lives by the mantra “any way you want it – quickly.” To accommodate shorter product life cycles for sheet metal assembly shapes and sizes that are constantly evolving, we take an agile and adaptive approach. Typically, small sets of products are moved from work cell to work cell along with each product’s priority. We also work with a computer driven “dispatch list” in each work cell.  Once parts finish “upstream”, they immediately show as available in the next work cell – and take their proper place in the queue of work in the next cell.  Of course we also have the ability to manipulate this list – to reflect the constant changes in customer demands.

What did that fan say? A few words from our W3GZ50 Axial fan.

Posted on Thu, Nov 08, 2012
by Lou Moffa, Market Manager - Refrigeration

W3GZ50

Our definition of "Giant" is continually evolving here at ebm-papst.  Our new W3GZ50 series EC axial fan has a 1250mm (49.2 inch) blade diameter and is currently the world's largest diameter EC air mover with integrated electronics!

Just like the other products in our EC giant line up, this new axial fan was designed from the beginning to be energy efficient, simple to use and able to be installed in a variety of air moving applications.  It can easily be customized by the end user so that it is a perfect match for use with refrigeration condensers, chiller applications or large scale ventilation applications.  Its large size allows you to reduce the number of smaller fans used.

A complete fan assembly like the W3GZ50 series streamlines your purchasing and inventory requirements.  The complete fan assembly has a motor, blade, venturi and finger guard that have all been designed to work together for maximum efficiency and eliminates the need to work with multiple vendors and patch together a fan assembly from various manufacturers.  A complete assembly can simplify your production line by reducing wiring and installation time.  

This air mover has an impressive list of features to match its size. 

-Air performance- the direct drive motor and blade combination are able to produce over 38,000 CFM and can operate efficiently with backpressure levels of up to 0.8 inches of water.

-Factory balanced blade - the rotating motor and blades are balanced as a complete assembly on the production floor to insure a smooth operation.

-Accepts traditional control inputs - So that you can fully speed control this fan in your application, our integrated electronics will accept a variety of control inputs.   For a simple set up, this means that you can use either a 0-10VDC input, 0-100% PWM input, or a 4-20mA input from an outside controller to completely vary the speed of the fan. 

-RS485 Modbus RTU protocol ready - Many of the previously mute devices that are part of our daily lives are starting to become vocal whether we like it or not!  Our cars, heating systems and even our home refrigerators are now capable of telling us what condition they are in with texts and e mails.  Our lineup of EC Giants that are over 500 Watts are ready to be heard as well!  If you would like this fan to be a vocal participant in your assembly, it is simple to establish two-way communication using the on board RS485 Modbus RTU protocol.   Not only can you command it what RPM to run at, but you can obtain the run hours, the specific alarm status, internal motor temperature and many other bits of information that will keep you informed and up to date for critical applications.   Our ongoing partnerships with key worldwide controls manufacturers make incorporating  digital communication  easier than ever before. 

-Built in PID controller- for ultimate flexibility, our built in process controller allows you to program this unit to run independently without the need for a separate process controller to handle common field tasks.  For example, when programmed to operate in closed loop sensor mode with your supplied temperature, pressure or other sensor, the fan will maintain a process specific set point.  Simply set the sensor parameters and how quickly you want the fan to respond and the process controller will take it from there.  The set point can be either entered using software to prevent unauthorized changes or from an accessible potentiometer for simple adjustments by anyone in the field.  This powerful feature is a perfect way to reduce components in your overall assembly.  Even if you choose to not use this feature as the main process controller, it can easily be programmed and can remain dormant in the background as a back up to the main process controller.

These are just some of the advanced features that this exciting new product has to help simplify your larger air moving projects.  

We welcome you to come see this impressive fan and all of our equally advanced products on display at the AHR Expo in Dallas.

How fuel scarcity drives innovation

Why brushless motor designs are gaining momentum for commercial truck and bus ventilation

By Bill McBaine

 

Not so many years ago, designers of commercial truck and bus ventilation systems had only a few choices for motors. These products offered economical solutions but were not without issues.

Then came a global fuel crisis, which forced truck fleet owners to re-think how they operate their vehicles. Because it was no longer fiscally practical to idle a large diesel engine during evening truck stops to power and ventilate the sleeper cab, HVAC manufacturers began to integrate their HVAC and power generation systems into auxiliary power units.

Mass transit authorities faced similar challenges: save fuel while providing adequate ventilation for passengers. They pushed for reducing buses’ down time and improving their life span, which required a new solution: a DC input motor device capable of drastically longer service life.

As a global manufacturer of air movers and drive systems, our challenge was to adapt to these new realities. The result? A brushless motor design that offers longer life, lower maintenance, better fuel efficiency and improved performance.

Let’s look at the old-versus-new options for powering ventilation systems in commercial vehicles.

Low voltage (12/24VDC) brush commutation motors, offered by many suppliers, were the standard for many years. Featuring a consumable carbon brush in contact with a commentator to provide power to various motor windings, they offered a simple, inexpensive approach. 

However, brush commutation motors have always been prone to wear-and-tear issues as they age.

The motor’s brush material is consumed over time through physical contact with the spinning commentator. This abrasive material becomes trapped within the motor, leading to bearing failure if it contaminates the grease. Typical brush life is 4,000 to 6,000 hours. “Long life” variations may exceed 10,000 hours but have unfortunately resulted in even greater amounts of abrasive brush material building up in the motor.

In addition, water penetration/condensation in brush commutation motors during extreme external temperature swings can result in moisture being drawn deep inside the unit (especially at the seams). Once trapped, this moisture cannot easily escape, leading to corrosion and shortened life span of the motor.

Another ventilation motor option, high voltage (230VAC) induction motors allow higher power levels at a lower amperage draw compared to 12/24VDC brush designs. On the down side, this approach requires a high-capacity AC power source, which adds a lot of additional expense to the system. These motors’ physical space requirements are also more suited to the mass transit industry/ bus market than for other types of commercial vehicles.

So what’s the third option? Automotive brushless commutation motors, which ebm-papst has refined over the past 10 years to offer truck and bus fleets better efficiency and performance.

W3G385

The brushless generation of automotive motors introduces a Gortex membrane within the electronics components, allowing any condensation to be safely eliminated from the circuit board. Leading suppliers of HVAC systems within moving vehicles and equipment have embraced these designs, now used in quantities of hundreds of thousands of pieces in commercial and industrial vehicles.

Our third generation W3G300 fan, introduced to North America in 2011, and the new W3G385 fan, which joins ebm-papst’s brushless motor product family this year, build on the success of earlier models while offering new capabilities such as greater air performance, thinner and lighter construction, reduced power usage and lower noise levels.

As fuel prices continue to rise, we’ll keep listening to the needs of our mobile customers and their HVAC suppliers, developing and testing new improvements to our brushless motor systems.

At ebm-papst, Every Day is a GreenDay!

Posted on Tue, Jun 19, 2012

Under rainy skies, a celebration of green

While last Wednesday’s showers prevented an outdoor celebration, the weather didn’t dampen our Every Day is a Green Day luncheon at ebm-papst’s US headquarters in Farmington, Connecticut. Employees have been preparing for this day by bringing their old and outdated electronic devices to the office for recycling.

P1012527 edit resized 600
Just a small sampling of the many electronics collected this week!

Employees also took the opportunity to purchase energy efficient and environmentally friendly CFL lighting from TechniArt, Inc. and had the ability to shred personal documents with Cintas.

After eating locally-sourced hot dogs, burgers and strawberry shortcake, we learned what many employees do to be green at home and work with a trivia contest.

The winning answers:

“At work, I requested a filtration system for the Deburring Machine, and was granted... My house has energy efficient insulation, windows, faucets, thermostats on a timer set for occupancy times, no greater than 58°F. We grow our own vegetables, fruits, have a compost bin for the garbage. I have rain barrels to catch rain water for plants, a wood stove heats our house. Our town has, and we utilize, a transfer station, recycle bins. We have solar panels for hot water. We have CFLs throughout the house (inside & outside).” Thomas Dunbar, Facilities Maintenance.

“I supplement my transportation needs with an electric bicycle of my own design. Counting the 28 miles I put on it this weekend, I’ve logged over 12,300 miles on it. I use solar thermal panels of my own design to supplement my upstairs heating in the winter time. The panels use a re-programmed older revision ALU board and sample 5000 series fans from the previous decade. I drive a Smart car which has cut my commuting gas consumption in half. I’ve switched over to LED lighting in approximately half of my household.” Charles Blow, Design Engineer.

We also formally ‘threw the switch’ on the power inverter to begin converting energy produced by the new, additional 50 kilowatts of solar panels on the roof of our production facility into power for our facility for a total of 100 kw now installed. When that power isn’t needed, we’re sending excess power back to ‘the grid’.

ebm-papst: The Future of Data Centers

Posted on Thu, Mar 15, 2012
by Joe Landrette, Market Manager at ebm-papst.

The US consumes about 4.40 trillion kWh of electric energy (Tomorrow is Greener 10/2011). Two percent of that power consumption, or 88 billion kWh, is used by data centers, which provide us with services like Apple's iCloud or Microsoft’s SkyDrive.

Because power savings is critical for hardware manufacturers and their customers, many companies are migrating from large facility data centers to portable/modular data centers that are often set up within sea containers. This new generation of data center is often fitted to house many racks of IT equipment that have ultra efficient cooling systems inside.

Not only can modular/portable data centers be manufactured and deployed more rapidly than traditional data centers, they also employ cooling solutions that can be 30 times more efficient than facility-style cooling systems and can save up to $500,000 a year in energy costs!

Because the majority of portable and modular data centers don’t have the same heat/cooling duct losses experienced in traditional data centers, the new configurations can super-charge their energy efficiency by incorporating ebm-papst’s range of EC blowers and fans, from our small 80mm fans up to 1250mm models.

The new modular/portable data centers also provide an opportunity for ebm-papst Inc. to offer builders air flow and design management strategies and custom sheet metal assemblies. Our products and engineering support services are helping shape how data centers are joining the earth-friendly movement and changing the future of both indoor and outdoor data storage.

For more information on Data Centers, contact Joe Landrette at Joe.Landrette@us.ebmpapst.com or call ebm-papst at 860-674-1515
