By using our compressors and air treatment equipment you will avoid dust, water or oil in your process. It’s important to have the right air quality to maximize your efficiency. If the air quality is too low, you will reduce the reliability of production equipment or processes. If the air quality is too high you’re wasting energy. Therefore it’s crucial to have the right air quality for your needs.
The right air quality to protect your production
The perfect installation for your requirements
You have to avoid 3 things: water, dust & oil contaminants.
Water
Water in compressed air leads to several issues, such as corrosion, icing, blockages and water hammer. All of them can damage your process and end product.
Dust
Dust in your compressed air creates extra friction, which leads to extra wear & tear in e.g. pneumatics. Our wide range of filtration solutions can remove all levels of dust in your system.
Oil
Oil particles entering the compressed air system can create product contamination and damage your end products. With our oil-free products and filtration solutions we can deliver Class-0 air for industries like food & beverage, medical & health care, textiles, chemical,…

Refrigerant dryer
Refrigerant dryers are the most common and consist of an air-to-air heat exchanger and an air-to-refrigerant heat exchanger. They are used to avoid free water and corrosion in the system. A relative humidity of below 50% is enough to achieve this. Both air-cooled and water cooled refrigerant dryers are available.
Twin tower desiccant dryers
Adsorption dryers are used when the compressed air application requires a pressure dew point below 0°C. The dryers consist of two pressure vessels. Both vessels are filled with desiccant. One vessel is removing moisture from the compressed air. 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 one saturated with moisture will be regenerated. It’s a cyclic process.
Filters
Atlas Copco offers a wide selection of filtration solutions for compressed air with different filter media and grades to remove any dust or oil from your compressed air system.
Rotary drum dryer
The rotary drum dryer is also using adsorption technology. The desiccant does not come in granular form. Instead it is bonded with a binding material in a honeycomb structure. This unique technology does not require any additional energy, as it is using the heat of compression. The rotating drum is divided into sections. In general 3/4 of the drum is used for adsorption, while 1/4 is used for regeneration. It’s a continuous process as the drum rotates and therefore doesn’t require any switching valves.
