How to Combat Rising Humidity with Compressed Air Dryers
In some parts of the country, April showers bring May flowers and a heavy dose of humidity that tends to hang around well into the early days of fall. With temperatures and humidity on the rise, your compressed air system will experience additional water loading on the air treatment equipment.
The Impact of Humidity on Compressed Air Systems
Removing moisture for corrosion protection is also important for the equipment using the air and the air system itself. Particulate created from rust and scale can foul lines and damage components of the air system. In the worst case, corrosion could lead to failure in the pipe work, creating leaks and preventing air from reaching the process where it is needed.
How to Remove Moisture from Compressed Air using Dryers
The following maintenance techniques can help keep your compressed air dryers operating at peak performance throughout the coming months.
- Refrigerated Air Dryers. To help these units perform better in warm and humid conditions, the air filter and evaporator should be cleaned to allow for maximum air flow. In compressor rooms that rely on outdoor air circulation, any louvers or fans should be set for their warm weather operating conditions. Drains on the dryer should be checked and maintained to prevent possible clogging.
- Desiccant Air Dryers use adsorption drying techniques to remove moist air. While not directly releasing water, a desiccant dryer will still be subject to more demanding operating conditions in warm weather because the units cycle more often with the higher heat and moisture. Maintaining exhaust mufflers allows lower back pressure during regeneration, increasing the dryer’s performance.
