An adsorption or desiccant dryer uses desiccant material to adsorb and remove the humidity from compressed air. It will come as no surprise then that the type and quality of the desiccant material are of the utmost importance. Adsorption dryers can only be effective and (energy) efficient if they contain quality desiccant. Pneumatech carefully selects the desiccant for its adsorption dryers from a wide range of premium European and North American suppliers. We base this selection on the following criteria: crushing strength, water resistance, anti-aging effect, and a revolutionary new technology. Here’s why each of those 4 criteria is so important.
Desiccant is subject to a continuous, cyclical load. Due to this load, low-quality desiccant will easily break up. This will cause the desiccant to quickly lose its water retention capabilities. In addition, it will create small dust particles that can block valves and/or clog the downstream dust filter and silencer. This dust can also create a health and environmental hazard during servicing. All of this means that quality desiccant offers a high crushing strength. The graph below shows how much higher the different desiccants that Pneumatech uses perform on crushing strength.

Subpar desiccant degrades when it comes into contact with liquid water. All Pneumatech adsorption dryers are equipped with water-resistant desiccant material in the bottom of the vessel. This improves the dryers’ performance and lengthens the lifetime of the desiccant.

All desiccants age, but some significantly faster than others. They degrade after a couple of months because of pressure, temperature or air humidity variations. This leads to performance problems and higher maintenance costs.
Pneumatech adsorption dryers come with desiccant material that is selected for its durability. In addition, they are overfilled to cope with this aging affect or with temporary overloads.

What if you could enjoy all the benefits of adsorption drying without the drawbacks of dealing with traditional desiccant material? That is no longer a hypothetical question. Pneumatech has introduced a new type of structured desiccant that revolutionizes adsorption dryer efficiency, performance and reliability. Traditional desiccant beads create a turbulent and unevenly distributed air flow. The straight tubes of our solid desiccant ensure a much more efficient air flow to give you significant energy savings. Solid desiccant also offers a 40% longer lifetime, eliminates the harmful desiccant dust and makes maintenance much faster and easier.
As you can see, desiccant quality matters – a lot. The right desiccant dryer with quality desiccant will reduce your energy and maintenance costs. It also improves your dryer’s performance and lifetime, and minimizes health and environmental hazards. All of which are important considerations.
If you need help deciphering which desiccant is best for your operation, the Pneumatech experts are always ready to help. As the leader in air treatment and gas generation, we can answer all your questions about air quality and dryers. And we can help you select the Pneumatech desiccant dryer that will best meet your needs.
A desiccant or adsorption dryer uses hygroscopic material or desiccant to remove moisture from compressed air and improve its quality. It consists of two towers. While one tower is drying air, the other is removing the moisture from already saturated desiccant. This so-called regeneration process prepares the desiccant for a new drying cycle.
An adsorption dryer is the preferred solution for applications that require very dry air (PDP of -40°C/-40°F or -70°C/-94°F), as it can reach pressure dew points as low as -70°C/-94°F. That makes desiccant dryers ideal for very cold climates, as they can help avoid ice formation in pipes and applications. They are also widely used in applications such as mold prevention, medical applications, textiles, and food factories.
Ash Air has a range of quality cycling and non-cycling Pneumatech refrigerated dryers for your air compressors.Our non-cycling Pneumatech refrigerated dryers offer a reliable and economic solution for removing moisture from your compressed air system. These refrigerated dryers for air compressors are easy to install, offer energy savings, prevent pressure losses, are equipped with rotary compressors and R410A refrigerant, and have improved connectivity features.
The Ash Air collection of very dependable cycling Pneumatech refrigerated dryers offer easy-to-use controllers, are easy to install with low maintenance needs, and are energy efficient with zero-loss drains.
We also supply a range of superior performance refrigerated dryers for air compressors with variable speed technology that matches energy consumption to the actual compressed air demand, have stable pressure dew points, and are available with both air-cooled and water-cooled condensers.
Our innovative desiccant dryers give customers efficient protection against the presence of any humidity in the air, which often is the source of pipe corrosion and decreased efficiency of equipment and tools.
The Ash Air range of advanced technology 360-1080 m3/hr and 1188-10800 m3/hr adsorption air dryers are for customers who have a focus on energy efficiency and low operating costs, while maintaining the highest standards in air purity. Our Pneumatech blower purge air dryers use heated blower purge air to remove moisture from the desiccant material, which means no purge loss during regeneration.

Where Should I Install my Air Dryer?
Your company purchased an air dryer for your compressor, now where should you install it? One of the most common things we see in the
industry are air dryers being stored on top of the compressors. Seems like a wasted space not being used on top of the compressor, right?
Wrong.
