The dryer will be connected to the air compressor and cool the air to a specific temperature. Your refrigerated air dryer will function much the same as an air conditioning unit. Refrigerated air dryers are one of the best ways to remove moisture from compressed air through a single unit drying system, but they can be very costly if sized incorrectly.
Because colder air holds less water, multiple systems are used to cool compressed air and allow water to drop out of the air to be collected and drained. If you want to remove water vapor, then you will have to use a dryer. They can only remove liquid moisture droplets from the compressed air system. Removing Moisture from Compressed Air through Dryersįilters and separators cannot remove water vapor.
Water will collect at the bottom of the trap and drain out while the air exits through a filter element. Water traps will work with filter regulators such that incoming cool air enters and circulates. Water traps are more common in applications requiring extremely dry air. To dry compressed air, the air needs enough time and surface area in the tank to cool such that the water vapor can condense into liquid water that needs to be trapped. Timed solenoid or automatic no-loss drains can also be valuable items put into the system (for tanks, filter housings, dryers, etc.). Consider some basic pipe fittings and a ball valve, which can make draining your tank a simple matter of just turning the ball valve a quarter turn. You can easily modify your drain to make it more easily accessible or automatic. You want to drain the air compressor after every use not only to keep moisture out but also to prevent rust or other damaging elements from amassing in the compressor system.
The mixture of oil and water that collects at the bottom of your air compressor is usually released through the valve found at the bottom. While some systems may be able to handle lower moisture content and do not require additional drying needs, many other systems are going to need air dried and moisture released in some form or another. The type of air compressor that you are using will ultimately determine the best way to remove moisture. Some systems might have far more complicated multi-stage air drying systems. The device used to remove moisture in your pressurized air system may be a simple drain valve. Any water or oil in the lines will be pulsed onto the filters which drastically reduces filter life, essentially ruining the filter media and efficacy.Ĭlean, dry, compressed air is required to ensure a dust collection system runs properly. Having moisture present in the lines can create havoc for filter pulsing systems as it may deliver moisture into the filter cabinet. If we see moisture in your compressed air lines during a service visit, we will bring this to your attention so your plant can address the issue with the compressed air supplier. Finding a solution to these kinds of issues is not always easy, because compressed air has multiple application functions and compressor designs. Moisture in the air will find its way into a compressed air system, and this can cause problems because air needs to be dry for an efficient system to function properly.
