In lieu of recent green energy initiatives over the past two decades, much emphasis has been placed on climate controls and global air quality. As nations move toward the enactment of their own anti-pollution goals, it is important to note that indoor air quality is a much greater cause of illnesses than air in an outdoor environment.
The U.S. Environmental Protection Agency noted indoor air can contain 100 times as many pollutants as outdoor air. Further, poor indoor air quality is one of the top five most pressing health risks facing general populations. This problem largely stems from the fact that people typically spend 90 percent of their lives indoors.
This issue grows larger during winter because people tend to stay indoors at even higher rates compared to other seasons. Buildings of all sizes are especially susceptible to harmful pollutants when they are not properly maintained and routinely checked for air quality. For instance, bacteria, mold, fungi, smoke, formaldehyde, radon, pollen and asbestos can all find their way into a structure with ease. It can sometimes take months or even years to detect these problems, which leads to negative health consequences for those in the vicinity, according to the American Lung Association.
The ALA indicated more than 40 million Americans suffer from allergies, asthma and other respiratory diseases, which are made worse by constant exposure to pollutants. In concern to large commercial and industrial settings, the prevalence of contaminants can be greater, affecting business operations, machinery, workers and the products being manufactured.
Large scale problems
In certain cases, like refineries, pharmaceutical warehouses, food storage centers and cleanrooms, poor air quality can cause a plant to be shut down. Many industries rely on the removal of air impurities specifically for the production and safety of goods.
To accommodate the strict regulations of commercial sectors, HVAC units are employed to regulate a variety of air controls, including temperature, humidity, moisture, ventilation and air quality. The coils inside of an HVAC system are responsible for heating or cooling filtered air while also eliminating the presence of pollutants. In the case of air conditioning and refrigeration, this is accomplished by the use of DX coils.
These coils, also called evaporator coils, exist for the purpose of removing leftover moisture after air has been cooled. When hot air enters into the system, it is run over a series of coils filled with refrigerants, thus cooling the air. This process occurs quickly, dropping the temperature of the air before it is forced out into an enclosed area. Because hot air contains more moisture than cold air, excess condensation is turned into a gas, whereby it is filtered out by DX coils.
Promoting air quality
Air is purified through the evaporation process, with water being drained away through a drip pan and moisture being removed immediately. When this occurs, the conditions for mold, mildew and other biological contaminants to form are eliminated. Without an environment in which to grow and reproduce, these pollutants are effectively stopped in their tracks before they start.
This is why top-of-the-line HVAC systems are in such high demand, because without properly functioning equipment, a building could be overrun with several different kinds of pollutants, all with harmful effects.
At Rahn Industries, DX coils are manufactured to custom specifications and can be installed quickly if damaged coils need to be replaced. With six types of evaporator coils to choose from, HVAC systems can be restored to their previous performance capacity.
On top of replacement coils, Rahn can also apply coatings on coils to prevent against corrosion that can lead to poor air quality. Rahn-Kote coating can increase the lifespan of coils and comes with a five-year warranty.
Rahn Industries has a full lineup of spray and immersion (dip)/ Bake protective coatings to meet your needs.
