Air has moisture and water vapor in
it. When your air compressor compresses this air, the air – and the moisture – are heated. As it cools, the air has less ability to hold
this moisture. Eventually, the air reaches a ‘dew point’. This is the temperature where the water vapor condenses into droplets.
Known as condensation, these droplets are basically just water, but still have the potential to cause great damage as
they flow through your compressed air line, machines and tools.
We recommend using an air dryer to remove condensation and moisture from your compressed air. Why? The condensation will result in:
• extra maintenance and downtime;
• a greater likelihood of corrosion and rust in boilers and piping;
• oil and lubricants in pneumatic tools and cylinders becoming contaminated and even washed out;
• blasting materials like sand clumping together;
• a kind of fogginess on surfaces you spray with compressed air.
A compressed air dryer removes the unwanted condensed water. The result? Dry air. No condensation. Less downtime. And one less worry to keep you awake at night.
The most common type of air dryers are cooling air dryers and adsorption air dryers.
Cooling air dryers, also known as refrigerated compressed air-dryers, circulate a cooling gas around your system, dropping temperatures to 3ºC or lower. This causes condensation; the dryers then remove it from the air before causes any damage. The process may sound familiar: it’s what domestic air conditioners do.
Worried about the effects of these cooling gases on the environment? Good news: Our ALUP dryers use R134a, R410A or R45A cooling gases. They have no influence on the ozone layer and less environmental impact than any other cooling gases.
Adsorption dryers are also known as desiccant dryers and ‘getters’. They blast moist air over hygroscopic material that removes the moisture from the compressed air. An obvious question: What’s hygroscopic material? The answer: Any material, whether it’s a solid or a liquid, that attracts moisture to it. This material will ‘get’ and hold the moisture. (Now you see why they’re known as ‘getters’.) However, this material needs to be replaced; otherwise, it will become saturated and stop removing moisture from the air. For this reason, adsorption dryers are usually used after a cooling air dryer when most of the moisture has already been removed.
Adsorption dryers easily reach temperatures below 0ºC. In fact, they’ll reach dew points of -20ºC, -40ºC or -70ºC. Cool, huh?
The choice of a compressed air dryer depends on what you’re using the compressed air for. There are often regulations involved (such as BRC, BCAS, IFS and Pharmacopoeia to name a few).
A cooling dryer is the most commonly used dryer for compressed air. By cooling the temperature to around 3ºC, most of the moisture condenses and is removed, leaving the compressed air suitable for 90% of applications. ISO 8573-1: 2010 purity class 4 is met by using a cooling dryer.
However, an adsorption dryer is a must if you need to reach a lower dew point. Adsorption dryers have pressure dew points of -20ºC, -40ºC and -70ºC. Adsorption drying is often used in the food, pharmaceutical, medical and chemical sectors.
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.
