Cleaning PPE at Half the Price

March 27th, 2013 by admin
Personal Protective Equipment

Cleaning PPE doesn’t have to come with a high price tag

Cleaning personal protective equipment (PPE) often comes with a high price tag, but failing to properly clean gear could cost even more and presents a serious health risk as well. Firefighters especially could find plenty of other uses for precious funds rather than paying for expensive, specialized equipment to clean and sanitize PPE.

Meeting the National Fire Protection Association (NFPA) 1851 standards for cleaning PPE at a fire station might mean shelling out $100,000 for an Esporta washing machine. The Esporta was engineered to clean equipment without the agitation found in most washing machines, and by all accounts it does an excellent job.

But the Esporta is a one-machine-fits-all solution, designed for everything from industrial and firefighting personal protective equipment to sports equipment and even wedding dresses. Different items require special cleaning formulations, meaning you pay for multiple settings and a lot of capability you’ll most likely never use.

A less expensive and more practical solution would combine an Omegasonics ultrasonic cleaner (cost around $15,000) combined with a Milnor industrial washing machine extractor (also about $15k). The ultrasonic cleaner gently cleans and sanitizes hard parts like helmets and boots, while the washer/extractor handles soft parts like jackets and pants. Allowing for soap and extra equipment, you will pay less than  $50,000. That’s half the price for the same cleaning capability necessary for personal protective equipment.

Wouldn’t it be nice to spend that extra $50,000 on something other than a high priced, multipurpose washing machine? Especially given that you’ll rarely if ever use most of the settings on the more expensive machine? Rather than take the expensive route to cleaning personal protective equipment, you could get the same clean for half the price, and still have money to purchase infrared imagers, extraction tools, or additional safety equipment.

Before you overspend, visit our website to learn more about how our ultrasonic cleaners, used along with Milnor’s industrial washer/extractors, can help you meet the NFPA 1851 standards for cleaning personal protective equipment.

Effective Water Restoration Techniques

February 5th, 2013 by admin

Water-RestorationThe goal of any water restoration effort is to return property to its pre-damaged state as fast as possible. To be fully effective, restoration companies must undo current damage and reverse time. Water has a way of seeping into areas unnoticed until it is too late. For this reason alone, restoration should be left to professionals.

When entering a water damaged area, make sure the structure is sound and the electricity is off. Mold and mildew can occur within 48 to 72 hours and flourishes in temperatures from 68 to 86 degrees Fahrenheit. Keep the area requiring water restoration well ventilated if possible, and wear rubber gloves, eye protection, protective clothing, and an organic vapor respirator. Place a fan in a window and clean toward the fan.

Items such as drywall, carpet, padding, mattresses, pillows, box springs and particle board should be discarded if wet. Remove portions of walls and insulation 15 to 20 inches above the water line. Base molding should also go. Flooring must be removed to expose pockets of saturation underneath.

Walls, studs, joists, subfloor and other damaged areas should be cleaned and sanitized. After a complete pressure wash with detergent solutions, they must dry thoroughly before water restoration continues. Floors, walls and ceilings should not be replaced until measurements ensure moisture content of wood is below 13 percent.

For household items, ultrasonic washing provides a more efficient method of cleaning than hand washing. Insurance companies pay water restoration companies by the box, regardless of the time it takes to clean items. By decreasing the time to clean each box, restoration companies increase their rate of return.

In addition, ultrasonic equipment provides a more thorough cleaning than hand washing, reaching even the smallest and most difficult places. Property owners get their possessions back quicker and cleaner, restoration companies see higher profits, and insurance companies get satisfied clients.

Training, Certification & Standards: Guest Blog from Total Contentz

December 19th, 2012 by Frank Pedeflous

Total Contentz

There are three strong keywords to success and profit in business. They are training, certification and standards. At first glance, training, certification and standards don’t mean much; it’s only when one explores what these words can do that you begin to appreciate their true value. Here’s why training, certification and standards should be on your mind and the tip of your tongue every day.

Training

tc-training-workshop-modifiedThe reality is that it’s just about all you have when it comes to getting employees, supervisors and managers to understand what you want done, how you want it done and why they should do it. Even customers need training so they will understand what you can and can’t do to their surfaces and furnishings during the cleaning and/or restoration process. Training and education are truly the foundation of a smooth running, profitable and successful business.

Certification

When shopping, customers look to differentiate one business from another. Advertising alone won’t do it, as everyone promotes themselves in glowing terms – whether it’s true or not. But not everyone is willing to go to the expense and effort of getting training, following standard practices or maintaining independent third-party certification. Training and certification in the eyes of the customer means that you have gone the extra mile and their chances of having a positive experience when doing business with you is much greater. Beyond that, certification means something to those doing the work. Like the business, certification means that the individual has gone beyond just doing the work; they have take training and passed a test and now have more than a basic understanding of the technical aspects of the work they do. In an employee’s eyes, this makes them special and it raises their expectation for themselves.

Standards

Industry standards are how we do things. A group of industry professionals has come together to write, review and establish what they see as best practices – the minimum acceptable standard for certain tasks and operations. Those following the standards have a much better chance that the desired results will be achieved when doing the work. Today, third party groups such as the American National Standards Institute (ANSI), ASTM International and the International Organization for Standardization (ISO) act as independent reviewers of the industry standards process to assure that policies are followed when establishing credible standards. In today’s competitive market, a business owner needs to do everything possible to set his business apart from and ahead of the competition. Training, certification and standards are three ways that identify a business and its technicians as special in the eyes of existing and potential customers.

Get Your Money’s Worth

Talk it up. Training, certification and standards should be seen as special in your organization, industry and marketplace. Promoting why your company and staff are different from the competition has to permeate your operation first and needs to be visible in everything you do. This indoctrination starts with the interview process for new employees, and continues in how you promote and pay workers. These same threads should be displayed prominently in your marketing to existing and new customers, and should be clearly seen in the way you do the work and operate your business. Take advantage of what you have accomplished. Inform customers verbally and in writing and show them in performance that both your company and your people are a notch above the competition. Display certification logos on vans, in ads and on business cards for all to see. Train workers to explain to customers what training, certification and standards mean to them, your business and your industry.

Ultrasonic Cleaning: A Primer

July 5th, 2012 by admin

This guest post was provided by Service Master Cleaning Solutions, a commercial cleaning company that offers maintenance solutions for Portland, OR.

Click image to see how saw blades can be cleaned using ultrasonics.

Ultrasonic cleaning — particularly that which involves cleaners that operate at the high and low ends of the ultrasonic spectrum — is truly coming into its own with each passing day. Industrial ultrasonic cleaners look somewhat like over-sized washing machines, and they can clean virtually any non-porous object that fits inside of them, from jewelry to musical instruments. Bench-top and tabletop models can clean smaller but vital objects ranging from saw blades to surgical instruments, and can provide the same level of cleaning to everyday objects.

The lower end of the ultrasonic frequencies is highly effective at shaking loose dirt, soil, salt, sand, and other particulate from a surface. The mid-range will remove grease, oil, and other adhesive materials that normally only come off with harsh soap or other cleansers. The highest frequencies the machines can reach — on the order of 130 kHz — will clean electronic devices in preparation for being assembled in a clean room.

Early ultrasonic cleaners suffered from a problem of dead spots — areas where there was no cleaning action due to the wave patterns exactly canceling one another out. Many objects also had complex geometries that created large internal areas where no vibrations could reach. Today’s ultrasonic cleaners solve both problems by varying their waveforms slightly over the course of the cleaning, effectively moving the dead spots around so that every surface is properly cleaned and finding the right waveform for every internal area.

Modern ultrasonic cleaners also generally feature a temperature-control option that allows you to set the internal temperature of the cleaning chamber to a range between 85 and 175 degrees. The hotter the temperature, the more effective the cleaning process. However, because many electronic and other components are thermally sensitive, the option for a ‘cold clean’ is a vital one.

How an Ultrasonic Cleaner Works – part 5 – Bubble Size

June 14th, 2012 by Frank Pedeflous

As discussed in the previous post, the choice of frequency is a major consideration in the process of ultrasonic cleaning. Frequency plays a critical role in determining the size of bubbles produced in the cleaning liquid. These bubbles ultimately create the agitation used by ultrasonic cleaners.

ultrasonic cleaning

Bubbles ultimately create the agitation used by ultrasonic cleaners.

Industrial ultrasonic cleaners operate at a variety of frequencies to accomplish a multitude of cleaning tasks in a wide range of industries. Low frequencies produce larger bubbles resulting in higher agitation energy and work well for heavy, coarse contaminants. Higher frequencies produce smaller bubbles and work best for fine particles or cleaning very small features.

However, operating continuously at a single frequency can produce problems. A fixed frequency can produce standing waves or harmonic vibration which may damage delicate parts. Harmonic vibrations are what allows the opera singer (at least in theory) to break the goblet.

To prevent ultrasonic cleaning from damaging objects being cleaned, the ultrasonic generator’s frequency may be swept back and forth over a small range of frequencies. By varying the frequency slightly above and below the central frequency, typically by 1-4 kHz, the risk of damage due to standing waves or harmonic vibration during ultrasonic cleaning is eliminated.

For example, if the central frequency is 40 kHz, the generator may sweep through a range from 38 kHz to 42 kHz during ultrasonic cleaning. With no one frequency being used continuously, standing waves in the liquid and harmonic vibrations in the object being cleaned will not be created

Choosing the right combination of frequency, range of frequency, as well as temperature and liquid to be used in a specific cleaning application can be challenging. Omegasonics offers vast experience in ultrasonic cleaning across numerous industries and cleaning requirements.

How an Ultrasonic Cleaner Works – part 4 – Frequencies

June 5th, 2012 by Frank Pedeflous

Ultrasonic cleaning utilizes the energy of collapsing bubbles to create an agitating action and clean objects on a microscopic level. Ultrasonic cleaners produce these bubbles when high frequency sound waves are transmitted through the liquid bath containing the object to be cleaned. The effect of temperature on the cleaning action was presented in a previous post. In this post, the effect of frequency has on the impact of industrial ultrasonic cleaners will be presented.

Sound waves are compressional waves.  This means the molecules of whatever substance they are traveling through (air or water, for instance) are alternately squeezed together and spread apart as the wave passes. When the frequency of a wave increases, the number of compressions occurring at a point each second increases. Since the wave moves at a constant speed, this means the compressions are closer together in space as well as in time.

Imagine watching as a train passes by. Now imagine counting the number of cars on the train passing by each minute. If the number of cars passing by increases, but the speed of the train stays the same, the cars must be getting shorter in length. As the frequency of cars passing by increases, the distance between the cars must decrease if the speed stays the same.

The result of increasing the frequency in ultrasonic cleaning is to reduce the space between compressions, which reduces the size of the bubbles created by the sound waves. This also reduces the energy released when these bubbles collapse. Therefore, industrial ultrasonic cleaners operating at higher frequencies are good for cleaning fine particles or very small features. Lower frequencies are best suited for heavy cleaning and coarse contaminants.

Ultrasonic Cleaner frequencies

Frank shares how different ultrasonic frequencies can effectively be used for various ultrasonic cleaning jobs.

Ultimately, the choice of frequency depends on the type of cleaning desired and the type of object being cleaned. In the final installment, we will discuss why the frequency must be varied throughout the ultrasonic cleaning process.

How an Ultrasonic Cleaner Works – part 3 – Temperature

May 22nd, 2012 by Frank Pedeflous

In our discussion of ultrasonic cleaners, we now turn our attention to the effect that temperature has on ultrasonic cleaning. Cavitations produced in a liquid by high frequency – or ultrasonic – sound waves result in streams of liquids essentially “power washing” objects on a microscopic level. What role does temperature play in the process?

As temperature increases, the number of cavitation bubbles at first increase before falling off. At the liquid’s boiling point, cavitation produced by ultrasonic sound waves introduced into the liquid stops completely.

Ultrasonic Cleaning Foil Test

In the foil test, the cavitation bubbles creates tiny pebbling patterns and holes in the foil.

In addition to a decrease in the number of bubbles, the size and energy of the streams they produce decrease as well. This can be demonstrated by a foil test, where a piece of foil is placed in industrial ultrasonic cleaners. The size and distribution of the holes produced in the foil reveal the characteristics of the cavitation taking place.

At higher temperatures, the holes in the foil are smaller and more evenly distributed. While the force of the cleaning stream is reduced, the overall coverage is increased. Finding the right temperature of operation may involve balancing these characteristics.

A figure of 60 degrees Celsius for a water bath is typically used. Generally, a figure of 65% of the boiling point of the liquid is used. The choice of temperature is often determined by the detergent used in the solution, if any. The detergents often have an optimum temperature, which takes precedence over the optimum temperature for agitation. If an acid is being used as a cleaning fluid, temperatures need to be kept as low as possible to prevent the acid damaging the stainless steel tank used in ultrasonic cleaning.

Next, we examine the effect of frequency on ultrasonic cleaning. The final installment looks at the need and advantages of varying the frequency.

How an Ultrasonic Cleaner Works – part 2 – Chemistries

May 8th, 2012 by Frank Pedeflous

In a previous post we examined the basics of ultrasonic cleaning, and learned how ultrasonic cleaners essentially “pressure wash” objects at the microscopic level. In this post, we take a closer look at the liquid medium used to transmit the ultrasonic sound waves and clean objects in industrial ultrasonic cleaners.

First, a brief review of ultrasonic cleaning. An ultrasound generator along with special transducers mounted to the bottom of a liquid-filled stainless steal bath, alternately compresses and expands the liquid between 25,000 and 130,000 times a second, depending on the application. This, in turn, generates bubbles, which collapse at high speed, increasing the temperature of the liquid and producing a high energy liquid stream which collides with the surface of the object being cleaned. Essentially, the object is cleaned with a high energy jet spray at the microscopic level.

Click on the above image to see how "chemistry detectives" can test different combinations of variables and chemistries to find the most effective ultrasonic cleaning recipe.

The choice of liquid for can have a significant effect on the performance of industrial ultrasonic cleaners. While water is most often the choice for ultrasonic cleaning, plain water can be augmented with detergents, or even replaced with other solvents in certain applications.

Adding detergents lowers the surface tension of the liquid which reduces the energy required to form bubbles. This can dramatically increase the cavitation, or process by which the bubbles collapse producing the high temperature liquid streams which clean the surfaces. The increased efficiency in producing this cleansing agitation along with the inherent cleaning properties of the detergent results in increased effectiveness of industrial ultrasonic cleaners.

The choice of cleaning medium (called the “chemistry”) is critical to the effectiveness of ultrasonic cleaning. The substrate – or material to be cleaned – as well as the kind of contaminants to be removed, are key factors to consider in selecting the cleaning chemistry. While water or detergents dissolved in water are the most common chemistry used in industrial ultrasonic cleaners, other solvents might by better suited for particular applications.

Future posts will look at additional ways to increase the effectiveness and efficiency of ultrasonic cleaning.

How an Ultrasonic Cleaner Works – part 1

April 24th, 2012 by Frank Pedeflous

All types of industries require highly efficient and effective cleaning of components – which is what ultrasonic cleaning provides – during various stages in their manufacturing processes. Ultrasonic cleaners represent a revolutionary breakthrough in the cleaning process. Industrial ultrasonic cleaners are not exactly new, but how they work may be something of a mystery to perspective users. The process is well-understood and well developed, so here is a brief explanation to demystify their operation.

Jay Leno uses Omegasonics Ultrasonic Cleaners

Click on the above image to watch Jay Leno demo his Omegasonics ultrasonic cleaner in his "Green Garage" by cleaning a piston that had caked on carbon, as well as a part that was heavily rusted.

Ultrasonic cleaning uses high frequency sound waves to agitate a liquid. The agitated liquid acts on and dislodges contaminants adhering to objects being cleaned. Ultrasonic means above the range of human hearing. Think dog whistle, although in many applications, the frequencies are even way beyond what a dog (or a bat, which actually sends out ultrasonic waves as a form of sonar) would be able to hear.

Industrial ultrasonic cleaners consist of an ultrasound generator along with special transducers (instead of speakers) mounted on the bottom of a liquid-filled stainless steel bath. The generator and transducers create waves in the liquid, which cause it to alternately expand and contract. This expansion and contraction will occur between 25,000 to 130,000 times a second, depending on the application.

The energy transmitted to the liquid from the transducers causes bubbles to form when areas of the liquid vaporize, becoming a gas. During the expansion phase, the pressure from the surrounding liquid on these bubbles decreases, causing the bubbles to expand. This, in turn, causes the water vapor forming the bubble to rapidly condense leaving behind a vacuum-filled “cavity”.

During the compression phase, the pressure on the cavity from the surrounding liquid leads to a sudden collapse, or implosion, of the bubble. The liquid molecules collide, releasing a vast amount of impact energy. This energy rapidly increases the local temperature producing a high-energy liquid stream that collides with the surface of the object being cleaned. This collision agitates the contaminants adhering to the surface, effectively and efficiently dislodging them.

Ultrasonic cleaning can be thought of as “pressure washing” at the micron level (that’s 1 millionth of a meter, or one-thousandth of a millimeter!)

Next, we will look more closely at the liquid medium used by industrial ultrasonic cleaners, as well as other ways to optimize the process for particular applications.
