Coil corrosion is an expensive problem in the HVAC industry, leading to coil replacement or entire system replacement. Corrosion results in failure, and is responsible for about 40% of equipment failures in industrial application.
Causes of failures:
- Exposure to harsh environmental condition like chemical, industrial and coastal or seashore area
- Highly corrosive areas like water treatment plants, sewers and high traffic areas
- Use of acidic or alkali for cleaning
- Two dissimilar metals (Cu + Al) Two dissimilar metals (like Cu + Al)
Effect of corrosion on HVAC
- Decreasing the capacity of HVAC system
- Increasing the power consumption of HVAC system
- Shortening the life expectancy of HVAC system
