If you are working in an industrial setting and require dry, clean air, an air compressor desiccant dryer can do the job. They work efficiently to remove water from the air to create a moisture-free environment. Using this type of air dryer, you will be left with high air quality at a reliable dew point.
Here is a short guide to air compressor desiccant dryers and why you should purchase one.
Purchasing an Air Compressor Desiccant Dryer
There are many air drying systems on the market, and so it is vital you make a purchase that suits your individual needs. Super Dry Systems can supply you with industrial equipment that will eliminate air from your environment. They are a desiccant air dryer manufacturer that specializes in designing, engineering, and manufacturing industrial air dryers. These air dryers can be used across a range of industrial processes. With over 25 years worth of experience, Super Dry Systems can help you identify the best air drying solutions for your organization’s compressed air needs.
Different Types of Desiccants
A desiccant is a type of absorbent material with a special affinity for moisture. They include silica, calcium chloride, calcium sulfate, activated charcoal, and aluminosilicate minerals. The hygroscopic properties enable this material to draw in moisture and retain water molecules in order to create a dry environment.
What is a Desiccant Air Dryer?
A desiccant air dryer can be used in industrial settings, such as in food processing or pharmaceuticals, whereby an immediate, dry environment is compulsory. They use desiccant materials to extract water from compressed air. Desiccant dryers are favorable over refrigerated air dryers as they can provide a lower dew point. Refrigerated dryers rely on a certain dew point to work. On the other hand, a desiccant air dryer can perform well in low temperatures.
The regeneration process takes place in air dryers with two towers. Once the materials become saturated with absorbed water, the desiccant is then regenerated for an ever-flowing drying cycle. Regeneration takes place in a tower that is not in operation. Regeneration occurs in the desiccant by dried compressed air, hot air, or specialized drying systems.
Regeneration Using Hot Air
This method requires a system that consists of a fan and an electric heater. Hot air is forced through a desiccant tower that has been saturated with water. Hot air is blown continuously until the moisture is gone.
Regeneration Using Dried Compressed Air
Small-scale dryers can use dried compressed air to dry the desiccant. This method uses part of already dried compressed air to regenerate the desiccant material. This drying technique is cost-effective and energy-efficient. However, it results in less compressed air that can be used for other means.
Desiccant Drying Using Special Drying Systems
Air dryers that use special drying systems benefit from desiccant regeneration and dried compressed air at the same time. These desiccant air dryers feature a rotating drum where part of the drum is in regeneration mode and part of the drum dries compressed air simultaneously.
