How does a desiccant air dryer work?
Desiccant air dryers work on a different principle—they adsorb moisture from the air stream and onto a desiccant material in a reversible process. Moisture-laden compressed air flows into the drying tower, where it passes over and binds to the porous desiccant.
How do adsorption dryers work?
Adsorption drying is a chemical process in which water vapor is bound to adsorption material that can either be a solid or liquid. The general working principle of adsorption dryers is simple: moist air flows over hygroscopic material — typically silica gel, molecular sieves or activated alumina — and is then dried.
How does a desiccant filter work?
A desiccant compressed air dryer uses a special material, called desiccant to dry the compressed air. This desiccant is made of a material that really ‘likes’ water, the water sticks to the surface of the desiccant. Every once in a while, the desiccant needs to be dried, or ‘regenerated’, to remove the water again.
What is air dryer purging?
When the air pressure becomes greater than that of the preset “cut-out”, the governor controls the unloader mechanism of the compressor to stop the compressor from building air and also causes the air dryer to purge.
What is the difference between refrigerant and desiccant dryer?
Refrigerated and desiccant dryers have the widest and most important applications respectively. Refrigerated dryers cover more than 80% of market needs and desiccant dryers are essential in industries where compressed air will come into contact with ingestible products and air systems.
Which material is used as desiccant in air dryer?
Desiccant types include silica gel, activated alumina, and molecular sieves. In some cases, more than one desiccant type can be used for special drying applications.
How does a desiccant compressed air dryer work?
A desiccant compressed air dryer uses a special material, called desiccant to dry the compressed air. This desiccant is made of a material that really ‘likes’ water, the water sticks to the surface of the desiccant. Every once in a while, the desiccant needs to be dried, or ‘regenerated’, to remove the water again.
What is meant by regenerative desiccant air dryer?
A standard desiccant dryer system uses a two-tower set up to ensure a continuous air drying cycle. What Is Meant by Regenerative Desiccant Air Dryer? The term “regenerative” is used to refer to an industrial desiccant air dryer that can renew its desiccant material by reversing the adsorptive process.
How often should you replace the desiccant in your air dryer?
A desiccant is very effective at removing water vapor from the compressed air, but it will wear down over time. To keep your air dryer at peak performance, you should plan to replace the desiccant every few years. The right regenerative desiccant dryer can protect your property, tools, and equipment.
What is desiccant and how do I use it?
Desiccant (sold separately) is required to remove moisture from air. To reuse saturated desiccant, heat it at its reactivation temperature until it returns to its dry color. For technical drawings and 3-D models, click on a part number. Max.
