Dear Chasity,

I am writing this letter to serve as both, a hearty thank you and a testimonial to the value of your product. I will provide some generic background on our situation, in hopes of helping others understand the true value of the Dirty Sox Kit.

In the winter of 2010, we were offered to bid on the installation of a new HVAC system for an operating suite at a local hospital. Upon reviewing the engineered drawings, I noticed some issues with the design, and contacted both the general contractor and the engineer to discuss descoping the project, and helping them fix a few flaws before construction. Both parties declined, citing both schedule and budget.

My issues centered on the use of a standard, packaged HVAC unit for the job. With the high rate of ventilation air required, the room pressurization scheme, and the lack of communication available to connect to the Building Automation System, I felt they were under designed, possibly due to inexperience of the team in this type of institutional environment. Since there was unwillingness on their part to discuss these issues, I did not submit pricing, even though this is a major client for us.

Once the space was built out and testing started, the issues became evident. Room pressure control wasn’t working correctly, there was no ability to adjust or monitor space conditions, and shortly after opening he room, organic odors started, causing the room to be closed in fear of infection control issues.

The installing contractor made a list of determinations, and each one was addressed. First up was the roof. They claimed the odor was coming from the rubber roof membrane under the roof curb. The unit was opened and cameras were sent inside the curb, while air samples were taken. No indication of problems were found.

They next blamed the odor on approximately 100 feet of ductwork running across the roof. It was claimed wet insulation on the duct was causing the odor. All insulation was removed and replaced. The odor remained.

The final claim was organic growth in the walls due to poor construction. Walls were opened and tested. The wall cavities were found to be clean and odor free.

During all of this, I remained in contact with the facilities director. We had told him confidentially from the first sign of odor that it was likely organic growth in the evaporator coil which couldn’t be seen, and which only smelled as the mechanical cooling ran and created condensate to wet the growth. This theory was presented to the installer several times, and they swiftly rejected the idea.

Two years after all of the money was spent for roofing, duct insulation, labor and anything else they could think of, there was desperation to get this resolved. They still couldn’t reliably keep the operating suite open on a daily basis.

With that, I offered to let them try a product I had found online called Dirty Sox Kit. In fact, due to the volume of business we do with them, the length of time the problems had been occurring, and my inexperience with Dirty Sox Kit, I offered to purchase it for them with no charge to them whatsoever. After a review of the MSDS, it was deemed to be safe to use. Upon using the Dirty Sox Kit product as per the manufacturers’ instructions, the odor was gone immediately, and the room has been in continuous use for several months now with no return of the odor.

I am convinced that this is a valuable addition to our product offering, and recommend it anywhere that we run across stubborn evaporator coil odors commonly referred to as “dirty sock”. Had the installing contractor known about this product, they likely would have saved over a hundred thousand dollars on unnecessary other repairs outside of their original scope of work.

Chasity, please feel free to use this letter to help others understand the value of your products. You may also have any contractor or end user contact me via email for verification of my story.

Respectfully,

John Flanagan
President

Techical Corner: The Science of Loafing Time

Life presents all of us with choices and decisions. When it comes to work responsibilities, machines have been increasingly valuable, giving us more time to accomplish other tasks. In addition to machines, our own ingenuity allows us to modify even our procedures to lessen work and time.

Human ingenuity has provided us with many devices that take away burdensome tasks, for example dishwashers or self-lubricating equipment or “automatic” temperature controls and so on. There is no question that such devices improve our quality of life, freeing us up to accomplishing other tasks or alternately just giving us “loafing” time where we can relax.

There are many jobs that are necessary but we don’t particularly care to do, like washing dishes or cleaning air conditioning coils often are put off until the last minute. Some of us might even like to put up a curtain to cover dirty dishes so we don’t have to look at them until we run out of dishes.

It is easier to put off cleaning with coil cleaning because the coils are already inside an area that we can not see anyway. No curtain is required here!

Tales of wasted energy efficiency from dirty coils and bacteria/fungus buildup (which are true by the way) do not seem to entice the average guy to clean coils more frequently. In this case the out-of-sight and out-of-mind concept applies.

Adding to the reluctance of cleaning coils in general is the rather significant fact that almost all facilities do not have the manpower to do it. So that pretty well seals the deal of only cleaning coils when the pressure drop is so high the air flow has dropped by 30% or even more.

While no one has yet to develop an in-place automatic machine to clean coils at the push of a button, human ingenuity has provided a solution.

It is more than just “nice” thing to do than cleaning coils – the benefits are there, and are proven accurate. Less back pressure on the fan system, less restrictions by fungus or mold and bacteria on the coils make significant differences in not only energy consumption, but air quality from the odors that dead and decaying microorganisms emit. Topping those factors off, wouldn’t it be just great to look inside of the HVAC air handler unit and see a glistening interior free from odors, free of any drain pan deposits along with crystal-clear water? And most importantly, with no extra work on your part?

A dream you say? No, it is simple and economical to have this now.

At CRT, our emphasis over the past 25 years has been in developing advanced products that keep air handlers looking nice where it counts – in the interior.

The development in our in-house R&D lab of these products using the latest technology we develop and manufacture in-house insures that any air handler using CRT solutions will be and continue to be clean. Benefits of increased efficiency, freedom for microbial odors, unexpected overflows and overall cleanliness are real. It has been said you could set up your office inside the air handler it is so clean. Can you say you could do that now with your existing air handler?

Whether you can or not, it will benefit you to look at the many unique products we have created at our website http://www.cleanac.com. Or, for extending the life of your air handler, check out http://www.pancrete.com to see how this simple to use product can give you more than you expected for your HVAC air handler.

From the Field: Dirty Sock Syndrome

Okay, it’s that time of year. For much of the U.S., the heating season began about a month and a half ago. Here in North Carolina, and more specifically my household, the heating season has only been around for about three weeks. Now don’t get me wrong, it’s been cold enough at night to run the heat, but during the day we find ourselves turning the AC back on – a common thing in the Southeast.

When the heat pump goes into defrost mode, or the HVAC unit is switched from heating for a brief time, then back to cooling, a condition known as “Dirty Sock Syndrome” can arise.  DSS is described as a musty, moldy, dirty sock odor coming from HVAC systems when they first start into cooling mode. DSS is caused by bacteria that attaches to, and grows on indoor evaporator coils. When the coils cool down and get damp, the bacteria release their gases all at one time into the air causing the unpleasant odor.

Some people have gone as far as to almost sell their homes because they couldn’t get rid of the smell. BUT HAVE NO FEAR! Here is a way for you to eliminate that smell and maintain a clean, healthy environment through a little preventive maintenance.

  1. Clean the coils at the end of the cooling season with Instant Powder Kegs. Cleaning the coils before the heating season will get rid of any contaminants such as dirt, biological buildup and other material.
  2. Sanitize the unit thoroughly. Use EPA-registered Fast Attack, an HVAC system sanitizer specifically designed for HVAC interiors. Iodine based sanitizers are an ideal choice, as iodine’s effectiveness has been well documented. Hospitals have used iodine to sanitize before surgery for the last 150 years for a reason!
  3. Protect the coil from fouling by using Green-Certified First Strike Micro Coat. Transform the coil into a “self-cleaning” coil, one that repels particles and keeps matter from adhering to the surface.
  4. Round off the procedure by adding a timed-release drain pan protectant. This will eliminate clogs and overflows that can occur once the cooling season starts back. Either Green-Certified PanGuard or EPA-Registered Algae Guard will work.

All of these products are safe and easy to use, requiring minimal PPE. By following these simple steps, it will ensure that when you start up your AC at the beginning of the cooling season, you aren’t left saying….“Ewww, THAT SMELL!”

Product Spotlight: Airing Out Your Dirty Laundry (Socks)

Practically all items inside of buildings contribute to indoor air quality. Everything from carpeting to office equipment release gases and particles known as volatile organic compounds (VOCs). However, the most referenced cause of indoor air quality concerns by tenant and workforce populations is the HVAC system. These concerns are a result of the strength and frequency of undesirable odors being disseminated by HVAC systems.

Contaminated outside air, bacteria and mold are thought to contribute to many health issues. Unfortunately this is quite common, as the interior of HVAC systems provide the perfect growth environment for spores to become active. Along with providing a dark, temperature-controlled area, HVAC systems remove moisture from the atmosphere providing mold spores with water, and remove dirt and debris providing mold spores with food.

Controlled Release Technologies, Inc. (CRT) has developed the following solutions to help buildings maintain positive indoor air quality, and avoid odor problems originating in the HVAC system. By using these products, air handler units can remain clean and sanitized. Additionally, the time between cleanings and the life of the unit itself can be increased, and the chance of poor indoor air quality can be dramatically decreased.

The Dirty Sox Kit is an annual, three-step application process developed by CRT that rids HVAC air handler units of odors by cleaning, sanitizing and protecting the evaporator coil. It is generally applied in the fall or winter months, and in systems where Dirty Sock Syndrome is thought to be present.

Dirty Sock Syndrome is a term coined by industry experts to describe unidentifiable odors which building occupants equate to the smell of dirty laundry or a gym locker room. Dirty Sock Syndrome is believed to be a result of bacterial growth on HVAC evaporator coils. The problem is generally limited to heat pump systems, but may be noticed in other system interiors.

Dirty Sock Syndrome is prevalent in buildings located in hot, humid climates, where there is a constant supply of moist air exasperating the problem. Because a microbial can grow quite rapidly, the emission of odors increases over time.

Follow these steps when applying Dirty Sox Kit:

  1. Apply Instant Powder Kegs coil cleaner to clean the evaporator coil of deposit buildup.
    Instant Powder Kegs is a concentrated cleaning powder, that is mixed with water at the job site, saving users expensive and unnecessary shipping charges. Instant Powder Kegs removes dirt and odor-producing build up that hinder the efficiency of HVAC systems.
  2. Apply Fast Attack to sanitize the coil, and remove any odor-causing algae, fungus, bacteria or mold.
    Fast Attack is an EPA-registered, concentrated antimicrobial that cleans as it sanitizes. Iodine was chosen as the active ingredient, as its effectiveness is well known and widely used in hospitals and laboratories.
  3. Apply First Strike Micro Coat to the coil surface to protect against future buildup of dirt and contamination.
    First Strike Micro Coat provides a clear molecular barrier (less than one micron), that does not inhibit heat transferability. Because First Strike Micro Coat has been extensively evaluated, it performs without maintenance attention for a year or more. This decreases redundant labor costs and coil cleanings, and keeps coils performing at optimal energy usage.
