Then, continue reading to discover the purpose of an air drying solution, the three types of solutions available to you, and the most common type on the market.

What Does an Air Dryer Do in a Pneumatic System?

Compressed air dryers play a crucial role in maintaining the efficiency and reliability of a pneumatic system. The purpose of an air dryer is to remove moisture from compressed air, ensuring that it is dry and free from water vapor. 

This is essential because moisture can cause various problems in pneumatic systems, such as corrosion, freezing, reduced equipment lifespan, and compromised product quality. When air is compressed, its temperature rises, leading to an increase in its water-holding capacity. 

As the compressed air cools down, the excess moisture present in it condenses, posing a risk to the system. To avoid water condensation and its detrimental effects, air dryers are employed. By removing moisture, air dryers help maintain the integrity and performance of pneumatic systems.

What are the Three Types of Air Dryers?

Heatless Regenerative Dryers

Heatless regenerative dryers are a reliable and energy-efficient option for drying compressed air. These dryers use adsorption technology to remove moisture. 

They typically consist of two towers filled with desiccant material, such as activated alumina or molecular sieve. While one tower dries the air, the other undergoes a regeneration process, allowing for continuous operation.

Membrane Air Dryers

Membrane air dryers operate by passing compressed air through a selectively permeable membrane. The membrane allows water vapor molecules to permeate while preventing the passage of dry air molecules. This separation process effectively removes moisture from the compressed air, providing a clean and dry output.

Refrigerated Air Dryers

Refrigerated air dryers are the most common type of compressed air dryers used in industrial and commercial applications. They work by cooling the compressed air, which causes moisture to condense. 

The condensed moisture is then separated and drained from the system, leaving behind dry air. Refrigerated air dryers offer efficient and cost-effective moisture removal, making them widely adopted in various industries.

What’s the Most Common Type of Compressed Air Dryer?

Refrigerated air dryers are the most common type of compressed air dryers used in industrial and commercial operations. Their popularity can be attributed to their effectiveness, reliability, and cost efficiency.

Refrigerated air dryers utilize a refrigeration system to cool down the compressed air. As the air is cooled, the moisture present in it condenses into liquid form. The condensed moisture is then separated and discharged from the system, leaving behind dry air that is suitable for use in pneumatic applications. 

The refrigeration system in these dryers employs a heat exchanger and a refrigerant, which cools the air to a temperature where moisture condensation occurs. The cooled air is then reheated before leaving the dryer, preventing any potential issues that extremely cold air might cause in downstream applications.

Refrigerated Air Dryers Offer Several Advantages

They provide consistent dew point control, ensuring a reliable supply of dry air. They are capable of handling a wide range of operating conditions and can effectively remove moisture even in high-humidity environments. Additionally, refrigerated air dryers are relatively easy to install and maintain, making them a preferred choice for a diverse range of businesses.
