Air handler interiors are dark and damp - ideal conditions for growing bacteria and mold. And indeed, they do grow well. Water drainage pans often are massively infected with mold and bacteria. Water drain pipes plug up biological matter, causing water overflows and property damage.
Biological growth also cause odors, sometimes offensive enough as to cause occupant complaints.
Using Pancrete to address these important issues helps markedly, but there are other factors also of importance which we will cover later.
EPA and Areas of Stagnant Water
Pancrete helps insure your air quality. The EPA recommends elimination of "dead" spots in the condensate pan where water stagnates. These stagnant areas assists mold and bacterial growth.
Pancrete prevents stagnant water by automatically self-leveling the pan. No areas of stagnation are left in the water collection pan.
Pancrete's Water-Repelling Surfaces
Pancrete has a "hydrophobic" surface to repel water - it moves quickly down the drain. This water repellant surface engineered in our labs is permanent. Pancrete application is simple enough to also provide a sloped surface to most air handlers, if desired, for ASHRAE 62.1.
Ability to Clean
Most metal and coated surfaces have areas of rust or porous surfaces where microbes can attach to and grow.
Pancrete has a smooth and non-porous surface easily cleanable just by using a squeegee. Simple.
Cleaning and Protection of Vertical Surfaces
This ease of cleaning is even more apparent when using Pancrete V-570 for vertical surfaces, fan enclosures, structural support members and filter racks. Why? The glistening white surfaces of V-570 makes noticing areas of contamination and mold easy. Cleanup is a simple wipe down. Without V-570, service staff would not notice dirt and biofilm build ups on rusted interior surfaces. Pancrete provides for easy cleanability while stopping corrosion from occurring in the future.
When Pancrete is used in conjunction with EPA registered Fast Attack HVAC System Sanitizer, a beneficial synergy occurs.
Air Handler Odors and Prevention
Hygiene is most important when we talk about air quality. Unfortunately, almost all buildings do not have the manpower necessary to provide adequate hygiene. It is of course costly to do so even if one had the resources.
It is known that microbes will grow not only in condensate water drain pans, but also on HVAC air handler interior sidewalls, structural support members, over insulation, on fan enclosures, cooling coils, and indeed on most areas with the air handler. Without some type of intervention, fungus and mold keeps on growing and growing, year after year.
Very often, the user cannot see this growth, as it takes the form of "biofilms" which are usually very small in thickness. The more the biofilms cover the interior surfaces of the air handler, the more odors that are emitted into air stream.
Pancrete is formulated throughout with anti-microbial properties to control the growth of odors from microbial causes. Because the anti-microbial is an intrinsic part of Pancrete and V-570, users are assured against product deterioration in its entirety, not just the surface.
EPA Registered Products and Treated Articles
There is a dramatic difference between a "treated article" and an EPA Registered product. A treated article merely is an article, such as a paint that contains an EPA registered anti-microbial only for the purpose of protecting the material itself from microbial degradation or odors. A perfect example is latex paint - this paint always contains an anti-microbial to prevent it from being degraded by microbes. Pancrete is a treated article per the EPA.
A few coatings are EPA registered in their entirety, such as our Bioflex anti-microbial coating for pipe coverings and pipe insulation. This product is throughly evaluated by the EPA for dermal, oral, ocular, and inhalation toxicity and found to surpass its requirements across the board. Because mold growth also occurs inside of the air handler insulation, it is quite impossible to get it out. Flex Seal is special very low VOC, NFPA 90A compliant coating developed to seal insulation, preventing fiberglass emissions, and providing a white, cleanable surface for insulation.
EPA Registration Numbers
The EPA registration number will always be found on the product label without exception. The first digits of the number are always the manufacturer of the anti-microbial and is called the "company number". The second digit of the EPA number references the specific formulation registered. For example, if we manufacture 4 products, our registration number would be 59682-1, -2, -3, or -5 depending upon which product it is. If a distributor purchases one of our manufactured products for resale, the second series of digits will always be followed with the distributors number, for example 59682-1-1234.
Because the manufacturer developed the formula and passed required evaluations to get a registration, often he would know more about the activity of the product.
All Pancrete family members guard against biological odors and against microbial attack on itself. This insures a long product life unaffected by microbes.
