Air Dryer
An air dryer is a system or piece of equipment used to remove moisture present in the air, specifically compressed air. Ambient air typically has a relative humidity of around 30 to 50%. Compressing air packs higher quantities of moisture in a small volume. This increases the relative humidity to 100% while the excess moisture that cannot be held condenses.
Air with high moisture content is detrimental to plant operation and reliability downstream equipment as it can cause process stream contamination, premature failure and wearing of instrument parts, equipment corrosion, and so on.
Importance of Air Dryers
- It removes water contamination
- Prevents water buildup
- Abates Corrosion
- Prevents freezing
- Improves the power of pneumatic equipment
- Inhibits microbial growth
