A desiccant air dryer is a common compressed air dryer for industrial and personal use. It is an absorption dryer through which water or liquid is eliminated from the compressed air. 

Whether you are running a small or large scale project where pneumatic systems are involved, you need the right compressed air dryer to effectiveness. 

Desiccant air dryers are not the only types of air dyer that exist. You will also find refrigerated, membrane, and chemical air dryers that serve the same purpose as a desiccant. All of these air dryers function differently and it is important to choose the right one. 

When you use a desiccant air dryer for your system, it helps eliminate excess water or moisture from compressed air, thereby preventing system breakdown or damage. 

If you have decided to use a desiccant air dryers for your project, you must go for the right one. There are two types of desiccant air dryers, the heat and heatless. 

To have a better understanding of what your air dryer needs are, you must do in-depth research of your project, the amount of moisture it requires, and its level of water sensitivity. 

These may not hold any importance to you but they go a long way in your choice of the air dryer. Also, you need to know the required dew point for each project or system and overall research on what project you are working on. 

Generally, any air dryer helps remove water vapor or excess moisture that could lead to eventual system damage from the compressed air. If you buy the wrong air dryer, it might cost you more money than you bargained for in terms of system repair. 

So, if a membrane air dryer will perform better than a desiccant air dryer, that is what you should go for. Buying an incorrect dryer can mar your entire project or cause system failure. 

Here are the most compelling reasons to buy the right air dryer;

• Buying the right air dryer helps avoid system and project failure. Failure could occur if you encounter a system breakdown or equipment damage. To avoid this, you should purchase the right air dryer, be it a desiccant dryer or other variants. 
• Purchasing the correct air dryer helps you save costs. Repairing a damaged system is more expensive than buying a new one in most cases, the saddest part is that in the long run, the incorrect air dryer becomes worthless to the project and you eventually spend another money to buy the correct one. To avoid this kind of trough, carry out due diligence, do a lot of research before buying a desiccant air dryer. 

It is important you spend some time reading and learning about air dryers before you make a choice.
