The problem that many companies face is reconciling utility costs with overall bottom lines. More so than in residential areas, commercial buildings are confronted with an even tougher challenge when concerning energy consumption and expenses.

Because commercial facilities are much larger, more energy is needed for basic functions like heating and cooling. Depending on market trends and economic conditions, expansion and construction of new buildings vary over time, largely correlating with availability and demand. The U.S. Energy Information Administration noted there was a total of 87.4 billion feet of commercial floorspace in 2012, with roughly 2 percent of buildings having 100,000 square feet or more.

Trying to manage temperature controls across such a large space comes down to having the right equipment and the proper maintenance. For the purpose of regulating temperature levels, HVAC units are employed to heat and cool buildings to optimal standards. In the case of cleanrooms, data centers and refineries, these units are also vital to promoting clean air and removing harmful impurities.

Identifying problems
HVAC systems are designed with a series of interior coils that are usually dozens of feet long, constructed in an end-over-end manner. With many return bends, the coils provide an enhanced surface area for air to pass through. Most HVAC coils are built with aluminum or copper materials, which, over time, have the capacity to corrode or malfunction if attentive care is not given.

Water coils are the main component from which heating and cooling processes derive. By pumping water through coils, the temperature of the air can be altered depending on how hot the water is. Hotter water naturally promotes heating while chilled water creates cooling.

When damages occur to these coils, the overall process of temperature control is restricted, leaving HVAC units to drain energy while producing very little output. These problems can arise out of corroded or damaged coils, bent fins or leaks, among others. Because water is involved in the process, rust can build up and force water coils to be replaced.

An experienced technician would be able to notice these signs, whereby further action can be taken to prevent similar events from occurring in the future.

Replacing coils
Because many facilities don't have the design and engineering technology to solve HVAC problems, they rely on outside engineers to develop performance selections for replacement coils which can be custom-made to fit into any HVAC unit.

A report from HVAC Investigators found that the average insurance claim for a damaged HVAC system was more than $20,000 in commercial settings in 2013. Additionally, 80 percent of all equipment failures were deemed fixable by making repairs.

Replacement coils are a great way to fix the source of the problem without having to make major changes to the system itself. Once inefficient water coils are removed from an HVAC unit, newer coils can be installed.

Rahn Industries specializes in replacement coils, with over 30 years of engineering, design and manufacturing expertise. Using the highest-quality materials, Rahn water coils can be built up to 40 feet long with tube diameters ranging from three-eighths of an inch to three-quarters inch. Water coils can handle temperature levels of 300 degrees Fahrenheit and are AHRI performance certified. Further, the tubes are reinforced and cased with 16-gauge galvanized steel so that coils last much longer and frequent repairs aren't needed.

Rahn can manufacture water coils specifically for the design you need or design improvements to make your coils more efficient. Rahn can ship new water coils directly, within a matter of days, putting your HVAC back on the right track. 

Rahn also has a full lineup of spray and immersion (dip)/ Bake protective coatings to meet your needs.
