Why coil corrosion could be the reason to your losses

It may come as a surprise, but simple pin hole leaks can be absolutely disastrous for your business. Anyone that has experience in the HVAC industry would swear by this – there are 100s if not 1000s of pinhole leaks that are caused by corrision every year that can bring your business down to your knees. The reason behind this leak could be anything, right from pollutants that are present in the air, humid conditions that aggravate salt – air, cleaning agents, pesticides, building materials and so on. Each of this can cause corrosion at specific points within the coild and cause a leak.

The simplest way to sort this is to have hydrophobic coated coils that would prevent any possibility of a leak. The kind of environment could have a telling effect to cause corrosion too and you need to be very vary of this.

So, what are the kinds of coil corrosion and what can you do about it?

There are two types of coil corrosion – formicary and pitting. You would be able to detect signs of this within a few weeks of installation and that would be your first sign to take action against the cause.

Formicary corrosion is because of the kind of organic acids that are used in the system like acetic and formic acids. This is available in abundance across homes in the forms of silicone caulking, cleaning solvents and even vinegar. Most of these products are found quite easily over the shelf. For example, latex paints and disinfectants are used quite often in both residential and commercial usages and that could be the reason behind formicary corrosion too. Now, the cathc is that the damage caused by this corrosion is not visible to the naked eye and could be easily missed out. The black deposits at times can be seen on the surface but is often ignored. The problem is that they form a sub-surface network of dots that are within the tubing wall and it resembles a minute beehive. This keeps getting bigger and within a matter of time causes a leak. It would be a lot easier to have it repaired right at the start than have to wait for heavy repair costs. The easiest way to avoid this to to avoid any of the above mentioned products in and around the coils and always have regular maintenance checks.

Having chlorides or fluorides around the copper causes pitting corrosion and this can be seen in items like toilet cleaners, dishwasher detergents and similar products. The biggest difference between both corrosion and this is that pitting is clearly visible to the naked eye. This is mainly because of the reaction between chloride with the metal surface on the pipe or coil. Once this grows, a leak is formed that causes dips in output. Avoiding sensitive material in the presence of such coils could be the simplest way to sort this kind of corrosion.

A simple check by the week could help you avoid such leaks. Regular maintenance coupled with the check should solve the problem.

Advantages of Using Aluminium over Copper for Making Coils

While people in the past have long preferred the use of copper for manufacturing coils, the scenario since a couple of decades has turned the tables. Aluminium has rapidly captured the market as the best metal for the production of coils for HVAC systems and many other industrial machineries. The simple reason that follows is the plethora of benefits that aluminum speaks which overdo its counterpart metals. The cost of using aluminum is also comparatively lower than that of copper, and this is one reason why the cost of products that have or are made using aluminum coils has significantly reduced. The number of aluminum coil suppliers have also increased since then.

Let’s take a look at how aluminum is better than copper. 

Cost and Pliability – Copper is comparatively a costlier metal. This means that the cost of making items that require copper also significantly increases. In order to reduce the cost of manufacturing units, aluminum is considered a better option. It has, over the years, also become a popular choice in the manufacturing market.

Pliability on the other hand, that defines the ability of a metal to bend easily, makes aluminum a more preferred choice. The metal can be bent easily into any desired shape. Hence, to make a coil of the same size and shape, manufacturers require three times less aluminum than copper, which further makes the process comparatively cheaper.

Strength and Reliability – While copper is easier to repair, a simple fact cannot be ignored – copper coil can break down faster than aluminum. The crux of the story, aluminum is much stronger and reliable than its counterpart metals.

Ease of maintenance – Most aluminum coil suppliers state that condenser coils are placed in units that are affixed in environments outside the house. This means that they are exposed to hard climatic conditions and need regular cleaning for better functionality. Installing aluminum coils is a better option because of their strength. They do get dirty, but cleaning them is relatively easy.

Corrosion – This is yet another factor that demands attention while choosing between the aluminum coils and copper coils. Corrosion plays a vital role in defining the life of a machinery, as it damages the coils which further hamper the working of the entire system. Corrosion damages due to humid climates are higher than other factors. The metal of aluminum when quoted with a special corrosion free element, can smartly stay intact for a longer period than in the case of copper.

The Advantages of Using Aluminium Epoxy and Hydrophylic Coating Coils!

When considering the performance and cost-effectiveness, there’s no doubt to the fact that aluminium is the best and the most appropriate fin material for the purpose of finned block heat exchange. Aluminium smartly side lines its counterparts with numerous advantages. To state some – its high transmission, resistance power, lightness, pocket friendly and easily availability are the major highlighting factors. However, there exist conditions wherein the metal may fail to stand true to its nature, such as in environments that are acidic, salty or moist. Aluminium fins degrade to quite an extent that they are only subject to replacement only. For such harsh conditions, special coating materials are used for extending the lifespan of the exchanger. Hydrophylic coated coils are an example to quote.

In addition to Hydrophylic coating, another most commonly used coating material is epoxy. The residence power to corrosion of these two coatings gives satisfactory results, and hence, they are widely accepted in the market as well. In addition to this, the two coating methods are quite economical and effective in nature. They help protect the metal’s surface against corrosive influences such as salt in air, humidity, and more.

In applications and equipment where water plays a major role, hydrophylic coated coils are used. This is because, water can be easily removed without it staying on the fin for much long. The coils are not easy to wet and hence, enable the incoming fluids to flow easily though the coils and off the outer surface well. Hydrophylic coating coils are primarily effective in areas where excess condensation takes place, such as that in the air conditioners, refrigerants, etc.

Moreover, the coating is also known for exhibiting fine performance – offering protection against water in high temperature areas and salty environments, specifically. Veterans of the industry state that aluminium surfaces when layered with blue hydrophylic coating performs 3 times better and longer under 5% NaCl spray than original, raw aluminium fins.

Thanks to such coatings that aluminium fins, the corrosive resistance of metals which are otherwise costly and daunting to process, can be obtained at a much economical rate. The larger picture to look at is that its essential to determine the need for accuracy and apply the coating to enable the metal to sustain its properties in long run. The better the coating, the more it shall bore benefits in the longrun. AHU coils used in refrigerants, air conditioners, heavy duty machines in industries and many home appliances, must have epoxy or hydrophylic coated coils.

Secured Prepaid Cards vs Prepaid Cards – Which one is Better?

If you’re looking for a credit card solution to put an end to your miserable credit history, it’s time to switch to a prepaid card. Apparently, one of the best ways to cap your extra expenditures and even start saving. Yet again, there are two types of prepaid cards – secured prepaid cards and prepaid cards. Though both are advisable and have the same features, they do come with some set of differences which makes one better than the other.

Secured Prepaid Cards vs Prepaid Cards

As just stated above, both secured prepaid cards and prepaid cards speak of the same set of features – for instance, you need to load money onto them, both of them can be used in place of credit and debit cards at a multitude of places such as at the grocery shop, a Cineplex, fuel station, a restaurant, etc. However, this is exactly where the similarities end.

In the case of a secured prepaid card, you need to make a security deposit of a nominal amount against the credit limit offered by the service provider, before you’re issued the card. The security deposit is placed in a saving’s amount until the time you’re availing the services of the card or are declared a defaulter due to excess expenditure.

When you’re using a secured prepaid cards, you’re in a way borrowing funds, as in the case of a credit card. Whatever you purchase or make payment through the secured prepaid card goes against your revolving credit limit and you must clear the dues every month to enjoy using it in the future. Once you make the payment, your credit limit, as set in the beginning revives and you can start spending again.

Prepaid cards, on the other hand, are different. In the case of prepaid cards, you need to pre-load money into the card in order to use it for making payments. Once you’ve exhausted the amount loaded onto the card, you cannot avail any credit money because there ain’t any credit limit attached to these cards. You will have to load more cash onto to the prepaid card in order to keep it functional.

Also, with prepaid cards, you don’t have to worry about making monthly payments on time and avoid becoming a defaulter. And, last but not the least, the biggest advantage of using prepaid cards is that they pose on effect on your credit history. No bad credit scored, no nothing!

Which one to buy?

It all depends on your needs and requirements. Precisely, if you’re someone who’s comfortable in paying a deposit fee and availing a credit limit with your card, then secured prepaid cards are for you. On the other hand, if you’re a shopaholic and wish to cap your expenditures, go for prepaid cards.

Evaporator and Condenser Coil Cleaning Made Easy: Learn Smart Ways!

If you’re an industrial contractor or a commercial worker and looking for a quick means to clean your HVAC coils, then this is exactly the spot to seek answers to all your questions. An air conditioner typically has two types of coils installed in it – a condenser coil and an evaporator coil. These are either made using copper or aluminium, or now-a-days most comes with a combination of the two – copper tubes with aluminium fins. While the evaporator coils are known as the cold coils as they help cool the indoor space. The condenser coils, on the other hand, are known as the outdoor coils and push out the hot air from inside the room to the outside environs. Since, these two coils are constantly at work and exposed to a number environmental factors, they wear and tear, get dirty and hence, ask for regular cleaning.

Dirty Coils are Money and Energy Wasters

A coil wrapped in dirt and grime cannot function as efficiently as it is supposed to. Dirt laden coils use almost 30% extra energy than those that are clean. Additionally, a grime system’s cooling capacity also significantly reduces. Hence, increasing operating pressure and temperature, which in turn, breaks down the compressor’s components and the equipment as a whole.

Frequent Coil Cleaning is Necessary


There are a host of means and methods to keep a condenser coil and an evaporator coil clean. If the dirt is less, you can easily wipe it off with the help of some soft bristle brushes. On the other hand, if the dirt is too much, it’s best to make use of some detergent solution that helps clean the dirt off the coils and keep them from withering off sooner than later. More aggressive deposits ask for stronger cleaning solutions. They must be used and handled with care. Coils can also be stream cleaned with some extra care. Pump sprayers too are a good option worth consideration.

Coil Cleaning Chemicals

There are a couple of alkaline and acid based chemicals available in the market that help clean the coils. But, many of them come with safety norms. If not used properly, with utmost care and precision, they can cause chemical reactions, damaging the coils.

There are many evaporator and condenser coil cleaners in the market that can help clean your HVAC equipment and appliances easily, quickly, and even offer year-on-year cleaning service at a great price, or, even do it yourself following simple steps.
