Formicary coil corrosion is caused by contaminants in the air that collect onto the condensation that forms on indoor coils during a cooling cycle,” Boyd explained. These contaminants turn into acids when they are exposed to the moisture, “etching the copper of the coils in a manner that looks like tunnels in an ant farm. Eventually, these etched areas of the copper become thin enough to start leaking as the copper becomes so thin that it becomes porous.
The corrosion initiates from the tube surface and progresses rapidly into the tube wall. The damage progresses rather quickly. Perforation usually occurs in weeks or months, not years.Questions on coil corrosion? Give us a call 239-596-5855.
