How to Select Right Air Compressor Dryer for your Application

The ambient air entering the air compressor always contains water vapor. At 75⁰F and 75% relative humidity, a 25-horsepower compressor will produce 20 gal. amount of water per day. This water vapor must be condensed and removed from the air system. Condensate is a contaminant that can adversely affect the final application. Failure to remove condensate can lead to corrosion, air leakage, pressure drop and scale formation in the distribution system.

Compressed air will concentrate the water vapor content. Compressed air also heats it and keeps the water vaporized. When compressed air enters the distribution system and cools, the vapor condenses. When compressed air expands from high pressure to atmospheric pressure, it cools further. Liquid water or condensate is unacceptable in many process applications and will contaminate the entire compressed air system.

Modern-day compressed air dryer technologies are numerous including refrigerant dryer, dessicant dryer, membrane dryer and Deliquescent dryer, you can see that there is no shortage of air dryer options. But of course, sometimes this may just be a problem. When there are too many choices, how do you know which one is correct?

Here are five tips to help you navigate among all possible options to find the ideal air dryer for your project.

1. Don’t Overestimate Your Needs

In some cases, it is not necessary to dry the air too much. In this case, part of the dry air will also work. If this describes your intended application, please realize that you do not need to purchase the largest, most advanced, and heavy-duty machines. Generally, products with lower strength can also work according to your needs.

Over-drying the air and reducing humidity far beyond the feasible range is wasteful. You may end up spending more money on a machine that far exceeds the equipment you need, and will eventually consume more energy than necessary.

2. Don’t Underestimate Your Needs

On the other hand, it is important not to underestimate your needs. If you need completely dry air, it is worth investing in more heavy equipment. Humid air can damage your project, costly maintenance work, and time wasted in solving problems.

If you really need a more powerful option, please buy it now. It will be worth it.

3. Be aware of ambient temperature

Consider the space in which your air dryer will work. What is the ambient temperature? Will the ambient temperature be lower than the temperature of the compressed air coming out of the dryer? If this is the case, you may experience condensation problems as the air is exhausted from the dryer.

4. Know your Required Dew Point

When you start your findings to determine the air dryer to choose, please pay attention to the dew point required for your application. Depending on the dew point, different air dryers will be used.

The required dew point will help you determine which air dryer is best for your application

For example, if you need a dew point of 32 to -40 degrees Fahrenheit, the membrane dryer will do the job correctly. On the other hand, if the dew point is below -40 degrees Fahrenheit, it is best to use a desiccant dryer.

5. Technical Evaluation from Compressed Air Experts

It’s always greater to get advice from your local Air Compressor Experts. This will not only benefit in selection of air dryer but also, for cost effective and optimized solution according to your needs.
