Working in an industrial setting requires a lot of energy to power all the heavy machinery needed to get the job done. One of the best forms of energy to power these tools is compressed air. When it comes to industrial setting, a large, industrial sized air compressor is the way to go to get the most power and efficiency for the most amount of tools at once.
The way a compressed air machine works is by filling up a large tank with air, then compressing it down through smaller chambers and tubes, before finally being pushed out of the system via an attached hose. The problem with compressed air is that there is a lot of moisture and micro particles, such as dust and oils, in the air being compressed. It is important to remove this moisture from your system in order to keep it contaminant free and running at full capacity.
In order to remove this unwanted moisture and liquid condensates in your industrial air compressor, you are going to need an air dryer, a device that is attached to the air compressor or built into the system itself that will keep moisture out of the pneumatic hoses.
There are three basis types of dryers that are used in an industrial air compressor: refrigerated air dryers, desiccant dryers, and dehumidifying membrane dryers. While all three accomplish the same goal of removing moisture from the system, they each go about this in different ways.
The most common type of air dryers today is the refrigerated dryer, which using a cooling method to reduce the temperature of the air, allow the water vapor in the machine to condense into a liquid form, and then have it easily drained away just outside the refrigeration chamber. The compressed air itself loses none of its power when it goes through the refrigerated chambers but the moistures are removed, making this not only a very efficient way of removing moisture, but also a safe and cost effective way.
The oldest type of air dryers are the desiccant dryers, which utilize chambers with desiccants in them to absorb moisture directly from the air without changing its temperature. A desiccant is a small cloth bag containing silica gel which absorbs water at a very fast rate and also retains that water so it does not leak out of the system. The cleansing of this system is a simple matter of going into the desiccant chamber directly and physically removing the desiccants, and then replacing them with fresh ones. This is another highly effective and cost efficient process, just be sure to always take care of the desiccants in the system.
The final type of air dryers is also the newest and uses a dehumidifier membrane at different stages of the compressed air process to remove all the liquid. This multiple step process is designed to filter out moisture and contaminants as they form in the compressed air system, and by running through several different levels of dehumidifiers, you can be assured that the compressed air in your pneumatic hoses will be moisture free.
As with all industrial air compressor parts, preventative maintenance is the golden rule to follow, and choosing the right kind of dryer is up to you and what you want out of your industrial air compressor system.
