Atlas Copco offers a comprehensive selection of compressed air dryers designed to meet the unique needs of various industries, ensuring clean, dry air that protects your equipment and enhances operational efficiency. Each type of air dryer is built to deliver optimal performance, energy savings, and reliability. Here’s a look at the different types of air dryers we offer:
Desiccant Air Dryers
Dessicant dryers (or Adsorption dryers) are used when the compressed air application requires a pressure dew point below 0°. The regenerative desiccant dryers consist of two pressure vessels. Both vessels are filled with desiccant. One vessel is removing moisture from the compressed air. Wet air passes directly through the desiccant bed which adsorbs the moisture. When this vessel is saturated with moisture the valves will switch and lead the air to the other standby vessel. During adsorption in the other vessel, the first vessel will be regenerated. It's a cyclic process.
Refrigerated Air Dryers
Atlas Copco’s refrigerated air dryers offer a reliable and energy-efficient solution to prevent moisture and corrosion in compressed air systems. With a simple plug-and-play design, these dryers are easy to install and require minimal maintenance, maximizing uptime and reducing production costs.
Featuring advanced Variable Speed Drive (VSD) technology and low internal pressure drop, they ensure optimal energy savings by adapting to fluctuating air demands. Using high-efficiency heat exchangers, these dryers effectively remove moisture, protecting your equipment and ensuring reliable, long-lasting performance across both air-cooled and water-cooled models.
The benefits of integrated dryers
You may be able to choose between a dryer integrated into the compressor canopy or a standalone model. In that case, the integrated version is often the better solution. A built-in dryer saves space, which is often a precious commodity in compressor rooms and on shop floors. It also reduces installation costs while offering a small, quieter and convenient solution for your compressed air needs.
Common problems our dryers help solve
1. Moisture Buildup and Corrosion
Excess moisture in compressed air systems can cause corrosion in pipes and damage to equipment, leading to costly repairs and reduced lifespan. Atlas Copco’s air dryers effectively remove moisture, ensuring your system stays protected and operates reliably.
2. Air Leaks and Pressure Drops
Air leaks and pressure drops are frequent issues that can increase energy consumption and reduce system efficiency. Atlas Copco’s air dryers help maintain consistent airflow and pressure, minimizing leaks and lowering energy costs.
3. High Energy Consumption
Inefficient air dryers can put additional strain on your system, leading to higher energy bills. Our air dryers are designed for energy efficiency, helping you reduce operational costs while maintaining peak performance.
4. Frequent Downtime and Maintenance
Poorly maintained air dryers can cause unplanned downtime, interrupting your operations and increasing maintenance costs. Atlas Copco’s air dryers are built for reliability and require minimal maintenance, ensuring maximum uptime and smooth operations.
With Atlas Copco’s advanced air drying solutions, you can overcome these common problems, protect your equipment, and boost productivity while reducing costs.

XDG
Compared to traditional purge and blower-heated dryers, it consumes up to 80% less power thanks to heat-of-compression regeneration and smart design. This means lower operating costs and uncompromised performance at ultra-low pressure dew points down to -90 °C/-130 °F guaranteed for critical applications.
MDG
The MDG heat of compression dryer is the world’s first dryer that provides a stable and guaranteed Pressure Dew Point (PDP) of -40°C (-40°F) at almost zero power consumption. The unit has no heating element, no blower and there is no loss of compressed air (purge). Its total power consumption is always below 120W.
BD
A reliable high adsorption capacity desiccant dryer for maximum performance with a pressure dewpoint of -40°C/-40°F. Allows for monitoring of all parameters to ensure maximum reliability for your installation. High-performance butterfly valves with actuators ensure a long lifetime.

FAQs
How do I choose the right dryer for my application?
Here is a helpful rule of thumb: If the pressure dew point is below 3°C (37.4°F), then it is likely that the right solution is a desiccant adsorption dryer, which can achieve a PDP of -40°C or lower. That makes them suitable for providing very dry air for critical applications. If your dew point requirements are less stringent, then you can probably work with refrigerant dryers.. Know more.
What is the most important internationally recognized air quality standard?
ISO 8573-1, the most important internationally recognized air quality standard. It tells you how many contaminants (in this case moisture) your air is still allowed to contain at a specific point in your compressed air system after it has been treated. Know more.
What is the pressure dew point (PDP)?
While the other contaminants have a certain threshold of particles or oil per cubic meter, the water in your compressed air is measured by its pressure dew point (PDP). The PDP is used to define the water content in compressed air. Essentially, it is the temperature at which water vapor condenses into water at the current working pressure. Low PDP values indicate small amounts of water vapor in the compressed air.
To make that happen, you need the right dryers and to choose the optimal technology for your application, you first have to figure out your dew point requirements. Know more.
What are refrigerated (or refrigerant) dryers?
Refrigerant dryers are the most common type of dryer. They consist of an air-to-air heat exchanger and an air-to-refrigerant heat exchanger. They remove moisture from your compressed air through condensation. Know more.
What are dessicant (or adsorption) dryers?
Adsorption dryers are used when the compressed air application requires a pressure dew point below 0°. The regenerative desiccant dryers consist of two pressure vessels. Both vessels are filled with desiccant. One vessel is removing moisture from the compressed air. Wet air passes directly through the desiccant bed which adsorbs the moisture.

It's a cyclic process. Know more.
What are membrane dryers?
These dryers are quiet, are easy to operate, have no moving parts, consume little power and require minimal service (mainly filters upstream of the dryer). They use a process called “selective permeation” of the gas components the air contains. The dryer consists of a cylinder that houses thousands of tiny hollow polymer fibers with an inner coating. Using their selective permeability, these fibers remove water vapor. This is how membrane dryers work: As wet compressed air enters the cylinder, the membrane coating allows water vapor to permeate through the membrane wall and collect between the fibers. Know more.
