Do Your evaporator coils need a protective coating?
As unprotected evaporator coils deteriorate, they shorten the life of your unit, leading to costly HVAC unit replacement. Coating the coils prevents harsh weather from damaging them and also protects your HVAC investment. The more you can protect your evaporator coils from corrosion and grime, the more efficiently your HVAC unit works.
What causes electroplated coatings to flake or peel?
When using a larger plating tank, agitation of the electrolyte plating solution is often necessary to avoid stratification and maintain a consistent temperature.
What are the factors that can cause a coating to fail?
These could include formulation, surface preparation, application, drying and curing times and conditions, and environmental exposure, with more than one contributing factor often being involved. Failures and defects can manifest themselves at various times in the life of a coating.
Which is the best coating for heat transfer?
This coating is very abrasion and chemical resistant, yet is extremely flexible for a coating of this type. Because of its ease of application, the coating maintains a uniform 1–2 mil thickness across and throughout the coil, minimizing the effects on heat transfer.
What causes the seals on an evaporator to leak?
It’s also quite common for corrosion inside the evaporator core to cause seals to leak. Corrosion occurs when debris finds a way into the air intake such as dirt caused by damaged or clogged air filters. 3. The Connection between Coil and Core. Another leak source is the connection between the ac evaporator coil and the core.
What are the symptoms of a broken AC evaporator?
A broken air conditioner may be a result of a faulty AC evaporator. Symptoms include weak air, strange odors, and fluctuating temperatures. What is the AC Evaporator?
What makes up the core of an AC evaporator?
As warm air passes along the evaporator coils, it collects the heat from the air and makes it cool. The cold air is then circulated through time cabin. Two specific components that make up the evaporator: the core and the coils. When issues occur, in most cases it’s due to leaks created in between these two parts.
Why does my AC evaporator have a sweet smell?
You notice a strange odor when using your AC system. If your AC evaporator is leaking, a small amount of refrigerant (not coolant) will seep from the coil, core, or seals. This will produce a sweet aroma, which might get more intense when the AC is turned on.
