The Importance of Insulation

If you follow our blog, then you know that we’ve discussed managing utility costs a number of times.  I focus on this subject because utilities can run 6 – 18% of volume, and I tend to see a lot of mismanagement in this area.  One easy way to help reduce waste, improve efficiency, and lower your utility costs is to properly insulate.

According to the U.S. Department of Energy, uninsulated steam distribution and condensate return lines are a constant source of wasted energy.  They further go on to say that insulation can typically reduce energy losses by 90% and help ensure proper steam pressure in plant equipment.  But let me tell you how I read those statistics – reduced utility expenditures equals a larger number on your bottom line.  So let’s get started.  Walk through your plant and take some notes.

• Are all pipes up to 7’ high insulated?  Not only will this help with waste, it is also mandatory for safety purposes.  Get this taken care of first so that the risk of employee injury is eliminated.
• Is everything that reaches or exceeds 120 degrees Fahrenheit insulated?  Check your boiler, supply and return steam lines, steam traps, and fittings.
• Consider insulating cold pipes, ducts, chillers, and roof drains - this will help control condensation and reduce the chances of deterioration.
• Before purchasing insulation, do your due diligence.  Take a look at using removable insulation covers or jackets on things like valves, steam traps, and boilers.  They are economical and provide easy access should the need for repairs arise.

Once everything is insulated, be sure to properly maintain both your equipment and its insulation.  Leaks and condensation can cause insulation to become wet, which will impact its effectiveness.  Be sure to replace wet insulation promptly.  If you have questions about insulating your dry cleaning and laundry equipment, simply contact us through our website. 

Heated Hydrocarbon Cleaning

Not only was the new Unipress Hurricane Double Buck Shirt Unit a hot topic at the 2015 Clean Show, heated hydrocarbon dry cleaning machines also generated a lot of buzz.  That’s because for years now, dry cleaners have been trying to find a more eco-friendly cleaning product that produces the same results as perc.  Unfortunately, few have performed at an adequate level, leaving many dry cleaners both holding off on upgrading equipment and wondering if there will ever be a magic bullet solution to the problem.

An organization in Texas conducted some testing using a hydrocarbon based cleaning solution, somewhere around 1970-1980.  Unfortunately, the testing didn’t progress too far.  We’re not sure why, but perhaps it had something to do with the machinery’s technology.  Fast forward to 2010, a long-time dry cleaning guru, recognizing that there needed to be an alternative to perc, analyzed the data from the previously mentioned testing and believed he’d found that magic bullet solution.  He also found data related to heat successfully cleaning industrial work gloves loaded with grease.  He believed that heat in conjunction with a high class petroleum based solvent was the ticket.

After hooking up with a dry cleaning friend that had a Georgia-based cleaner and specially ordering a machine, they started testing the theory.  Somewhere along the way, in addition to the heat, he determined that the proper detergent played an important role, and Wes Brunson with Fabritec International supplied that missing piece.  The results were simply amazing.  Pre-spotting, with the exception of things like ink, blood, and paint, all but disappeared.  Grease stains were removed easily.  Food spots were coming out 99% of the time without pre-spotting.  Dark loads were getting a 98% pass rate.  Many beaded and embellished garments could be cleaned with this method.  Whites were coming out brighter than if they’d been wet cleaned.  The fibers relaxed resulting in a nicer feel to the hand and fewer wrinkles on the garments, which translated into reduced finishing times.  And as an added bonus, there was no odor.  There is one catch -- these results came as long as everything is done properly -- the right programming in the right machine with the right detergent, but “the magic is in the heat”.

“The dry cleaning industry has long been looking for a viable alternative to perc,” said Kevin Lawson, Vice President of Tri-State.  “With its success in stain removal and reduction in waste, I see heated hydrocarbon as the future of the industry, possibly replacing perc permanently.”  If you are one of those operators that’s been holding off dry cleaning equipment upgrades or purchases for the arrival of the magic bullet solution, now could very well be that day.  Need help getting started?  Simply call us at 866-885-5218; we are here to help.

Used Unipress Equipment

Last month, we shared some information about the new Unipress Hurricane Double Buck Shirt Unit that was unveiled at the 2015 Clean Show.  It is an impressive piece of shirt laundry equipment and will most likely entice many operators to upgrade.  Translation – that Hurricane will have to replace something, and I see an opportunity for others to upgrade to a high-quality piece of Used Unipress equipment while saving some money.  Here are three great Used Unipress pieces out on the market right now:

• The Unipress NT, the first in the Lightning Series, boasts features like a contoured chest, side air bags, and dual timers.  It is a sturdy and reliable piece of equipment that has stood the test of time.  While this press is no longer in production, parts are still readily available should a need for repairs arise. 
• A piece of Used Unipress equipment we really like is the second generation in the Lightning Series – the Unipress AP.  It can produce 90 shirts per hour on a double buck and 50 per hour on a single buck.  Not only does the AP produce a beautiful shirt, it also has an open design for easy maintenance, microprocessor controls with self-diagnosis, and is easy to operate. 
• Unipress LS – This press is the third in the Lightning Series and is designed to produce the highest-quality shirt, increase piece count, and reduce labor costs.  Features we love include foot operated clamps, scheduled maintenance notifier, and microprocessor controls with self-diagnosis.

No matter what piece of used laundry or dry cleaning equipment you are looking for, make sure you work with a reputable company that discloses what repair work has been done on the equipment.  We fully disclose all repair work before selling any piece of used equipment.  Additionally, many distributors sell used equipment as is.  We offer a 90 day parts only warranty many of our pieces of used laundry or dry cleaning equipment.

Unipress Hurricane

I love attending The Clean Show.  It provides an excellent opportunity to check out the latest in technology and to talk one-on-one with the companies we partner with.  Probably the most looked at and most talked about item at this year’s show was the Unipress Hurricane Double Buck Shirt Unit.  I’d like to show you a photo of this unit, but as you can see, there was a mob surrounding it the entire time.

You can check out the Unipress website to see photos and to get more detailed information about this piece of shirt laundry equipment, but let me tell you what I like about it:

• The Unipress Hurricane has a touch screen to monitor production, but that’s not the end to the touch screen’s capability.  When an error occurs, the screen lets the operator bring up the manual at the point of error and then identifies the parts needed to correct the issue.  This gives the operator all the information needed to pinpoint and communicate the problem to the mechanic, who can show up prepared with all the parts needed to fix the problem.
• Unipress by far manufacturers the best shirt unit on the market.  That being said, no piece of equipment is perfect.  In the past, there have been issues with rubber hoses cracking causing units to lose vacuum.  They’ve solved that problem in the Unipress Hurricane unit by re-engineering it to eliminate rubber hoses and vacuum lines and then replaced them with aluminum tubing.
• Finally, they did some fine-tuning on the tensioning arm by both beefing it up and adjusting it towards a more natural angle.

  

Apparently I’m not the only one impressed by this updated shirt unit.  Sales of the new Hurricane far exceeded anyone’s expectations.  I can see why.  It’s a fantastic piece of equipment.  If you’re in the market for a similar piece of equipment, Tri-State has a great selection of used Unipress equipment.

  

Refrigerated Air Dryers

A recent conversation with a customer in Texas about refrigeration air dryers led me to think about a pattern we have with our maintenance calls.  As you know, every press in every dry cleaning facility operates by air-activated cylinders to either raise and lower or close and open ironing heads, transfer forms, and such.  Each one of those cylinders has a rubber O-ring that is affected when moisture mixes with the lubricant at the seal.  The problem that many facilities experience is that the air going to the equipment has too much moisture, which ultimately creates maintenance problems and costly repairs.  Unfortunately, many folks tend to ignore this issue; however, with just a little planning and effort, this issue could actually not even be an issue at all.  Here are my three suggestions to help remedy the problem.

1.  Installing your air compressor in the boiler room seems like a logical choice given the amount of noise it produces; however, the boiler room has both a higher temperature and higher humidity than the surrounding area.  Instead of taking in ambient air from that humid environment, we suggest that you pipe the intake to pull air in from outside the boiler room.

2.  Install a refrigerated air dryer.  Here’s how it works – warm wet air enters the dryer and is cooled down.  The moisture that was in the air condenses to water, and that water goes into a water separator bowl and filter.  What’s left is dryer air, which is reheated to room temperature to keep the outside of the pipes from sweating.

3.  Your last line of defense is to install an oil water separator on each press.  This device is designed to keep water from mixing in with the lubricants and getting in your rubber seals and valves, ultimately leading to premature valve failure.  The photo below is of a combination separator/filter/regulator.

Graying Garments

A common complaint among frequent dry cleaning customers is that their white and light colored garments look dingy – sometimes referred to as ‘graying’.  This issue comes from redeposition – a situation where the dirt, dye, spotting agents, and body oils from dirty clothes get suspended in the dry cleaning solvent.  Those soils are then redeposited back on to garments in future loads.  Along with the garment’s dingy look, there sometimes can be an odd odor as well.

What causes redeposition?  Actually a number of things, so we’ve come up with a list of the most common causes:

• Using dirty solvent.  Most dry cleaners distill their solvent constantly so that each load is cleaned in clean solvent, but there are some discount cleaners that try to save money by running this process only periodically.   The result is clothes being cleaned in solvent that is at best, murky and at worst, brown.  Your solvent should always be clear.
• There is a lack of solvent exchange between the drum and filters.  There could be a number of issues causing this including dirty or clogged filters that don’t allow the solvent to pass through; a clogged pump strainer; a malfunctioning tank inlet/outlet, filter inlet/outlet, or wheel inlet/outlet valves; the pump not pumping because of either a clogged button trap or a malfunctioning valve at the button trap causing the pump not to have suction.
• Clogged bleeder lines for the filter housings, an issue that is often overlooked.  Each filter has a bleeder line to bleed off air and ensure that the filter is completely full of solvent.  These lines can clog with lint, causing the filter to not completely fill.  That means you could be operating with only half the filter area of your filter system.
• Dirty carbon filters.  Carbon filters are used to remove dye and should be changed every 1200-1500 pounds of cleaning each.
• Improper sorting.  Not only should you sort your loads based on color, you should also sort for weight.  Be sure to run lighter weight garments separately from heavier weight items.
• Overloading the machine.  If the machine is too full, it won’t allow the solvent to move around the wheel properly, causing removed soil to remain in contact with garments longer.

The good news is that the graying color can many times be removed by simply cleaning the garments again in fresh solvent.  If you’ve had customers comment on their whites, do some investigating.  If the list above doesn’t solve your problem, then contact us at tristatelaundryequipment.com or 866-885-5218.

Professional Wet Cleaning

When did people start cleaning their clothes?  I suspect it’s when they started wearing them.  Though I suppose that they didn’t clean them quite as often as they should have.

Web sources site the first form of dry cleaning being used by the ancient Romans.  According to ecocleanaustin.com, they used ammonia and fuller’s earth to launder their woolen togas.  Fast forward to the 19th century where Jean Baptiste Jolly, a French dye-works owner, noticed that his tablecloth became cleaner after his maid spilled lamp oil on it. He then developed a clothes cleaning service using this process which ultimately became known as dry cleaning.  According to drycleancoalition.org, perc became the solvent of choice for dry cleaners in 1962.  In recent years, however, the use of perc has declined as more environmentally friendly options arose.
 
Recently, I had the pleasure of speaking with David Knight of Kreussler, Inc. about an ever growing in popularity alternative to dry cleaning – professional wet cleaning.  David explained that Kreussler, Inc. developed this process in 1985 as a healthier alternative to solvent-based cleaning processes.  Professional wet cleaning is the practice of cleaning dry clean only goods in water.  But please take note - professional wet cleaning is not like doing laundry.  Professional wet cleaners use specialized equipment and processes to safely care for garments.  It takes more than just having the special equipment to professionally wet clean a garment.  It also takes considerable knowledge and skill as most items being cleaned are not durable goods but rather more fragile pieces.  The specialized detergent must do the cleaning so as to eliminate the mechanical action that could lead to shrinkage and dye bleeding.  In addition to the specialized detergent, a conditioner must be used so that the fabrics won’t get hard and rough to the hand.  Finally, garments must be properly finished.
 
Why might you want to add a professional wet cleaning system to your dry cleaning plant?  First, there are lots of garments that cannot be dry cleaned.  For instance, items like beaded dresses, wedding gowns, and silk items are sometimes better suited for professional wet cleaning.  Second, water soluble stains tend to come out easier in professional wet cleaning; it’s not that dry cleaning cannot remove them, it’s just that there will be a lot of spotting to get the same result.  Third, more of the garments manufactured these days are washable as opposed to 30 years ago when everything had to be dry cleaned.  Finally, professional wet cleaning doesn’t produce any hazardous waste.

There are lots of great companies out there that are heavily invested in wet cleaning soaps, conditioners, and processes.  Besides Kreussler, companies such as Electrolux, Fabritec, Faultless, and UNX are leading the way in this exciting industry.  If you are interested in learning more about professional wet cleaning, feel free to contact us.  We are happy to answer any questions you might have.
