CompAir offers a full range of energy-efficient and environmentally friendly compressed air dryers including refrigerant, modular desiccant, and heatless desiccant as well as HOC dryers. All of our technologies are engineered for maximum reliability, long life cycles, and easy service access, so whichever technology you choose, you can be sure your investment offers undeniable performance.
Air is a colourless, odourless, tasteless mixture of many gases, primarily nitrogen and oxygen. It is naturally contaminated with solid particles, such as dust, sand, soot and salt crystals. This contamination varies with differing environments and altitudes.
Water vapour is another natural ingredient that can be found in variable amounts in the air. The amount of water vapour and contamination of the air plays a vital role in the compression process and in the quality of the air delivered by the compressor.
The damaging and corrosive properties of water are well known. Untreated air at atmospheric pressure contains large amounts of water and other contaminants such as oil droplets and dirt particles.
When the air is compressed the concentration of moisture and other contaminants increases. If allowed to remain in the system, this corrosive mixture has a detrimental effect on pneumatic equipment, causing unnecessary production downtime, product spoilage and reduced equipment life.
Compressed air dryers are used to remove moisture from the compression process, protecting equipment and products from harm and ensuring clean, dry air quality.
Untreated air can cause corrosion and damage to your pipework and the internal structure of your air compressor. This can eventually lead to a system breakdown, costing you time and money. Compressed air dryer will help to keep your system running damage-free and your operation safe and reliable with long term results.
Whatever your application, you need to be sure that your end-product is of high quality. Air that contains water vapour can cause product spoilage which can be very costly to businesses. Compressed air dryer ensures that air is pure and dry before it reaches the point of use.
Peace of mind
Modern production systems and processes demand high quality compressed air, which is defined in the 6 classes outlined in international standard ISO 8573- 1:2010. These are only achievable with filtration, water separation and drying. Trust powerful compressed air dryers to offer complete reassurance and total peace of mind for your business.
Refrigerant dryers are the most common type of drier technology used by many industries. As the name suggests, heat exchangers are used to cool compressed air which will condense the bulk amount of water vapour within the air. Once the compressed air is cooled and water is removed, the air is reheated to around room temperature to ensure no more vapour forms within the pipe system.
CompAir refrigerant dryers are characterised by their energy efficiency, which helps to reduce running costs thanks to their patented heat exchanger technology. The CD series of refrigerant dryers offer a host of benefits to the user including:
The CD-series refrigerant dryers deliver a comprehensive, cost-effective solution to multiple applications across a wide range of sectors including automotive, manufacturing, petrochemical, oil and gas, dry cleaning and light processing to name a few. They offer a fantastic return on investment and are available in a wide range of airflows. Read our brochure on the downloads tab for more information.
For CompAir, quality and efficiency are just as important for compressed air treatment as they are for compressed air generation.
Just like CompAir compressors, the CD-Series refrigerant dryers also provide a consistently high performance with optimum efficiency for many industrial compressed air applications. They are carefully selected depending on working conditions with continuous dew point monitoring enabling reliable operation with the lowest possible pressure losses and running costs. When it comes to compressed air treatment, modern, reliable technology and compact dimensions make the CD-Series the preferred choice for every application.

High-performance desiccant air treatment
Desiccant dryers work on the principle of moisture always migrating to the driest medium possible. Therefore, water vapour is removed from compressed air by passing it over an adsorbent desiccant material.
As the air contacts the adsorbent material, water vapour transfers from the wet air to the dry desiccant, however, adsorbent materials have a fixed adsorption capacity and once this capacity is reached, they must be regenerated or replaced.
Therefore, to provide a continuous supply of clean, dry compressed air, adsorbent dryers utilise two chambers of desiccant material and at any one time, whilst one chamber is on-line, drying the incoming compressed air, the other is either off-line, being regenerated or is re-pressurised, ready to come on-line.
All desiccant dryers remove water in this manner. The energy consumed by a desiccant dryer can be directly attributed to the method used to regenerate the adsorbent material. The CompAir A-Series dryers utilise the heatless PSA method to regenerate the adsorbent material.
The A Series utilises the latest technology from CompAir to provide an energy efficient solution at the lowest life cycle costs. The same quality, performance and efficiency standards delivered by the compressors can now be enjoyed from the air treatment range, including the below advantages:
The new downstream portfolio manufactured by CompAir utilising the latest technology, provides an energy efficient solution at lowest life cycle costs. The same quality, performance and efficiency standards delivered by the compressors can now be enjoyed from the air treatment range.
Investment in a manufacturing site in addition to the support teams, ensures that compressed air operators don’t need to worry about the quality of their compressed air – quality that is key to ensuring maximum production efficiency and investment protection.

For many oil-free applications the heat-of-compression drying process is the most energy efficient way. CompAir offers a range of highly efficient HOC dryers offering lowest operating costs and extremely low-noise operation.
The Sub Zero Dryer is a high efficiency alternative to traditional desiccant type dryers
for ISO Class 3 (-20 degC PDP) applications. It is an innovative new type of dryer that
provides lower Total Cost of Ownership than ever thought possible, compatible with all
types of compressors, no purge loses, and provides consistent PDP performance regardless
of changes to air demand or ambient conditions.
The revolutionary CMT dryer is the only regenerative refrigerant dryer available in the compressed air market today. It combines the sub zero pressure dew point (PDP) of a typical regenerative desiccant dryer, with the low operating and energy costs of a refrigerant dryer, to provide an extremely low total cost of ownership (TCO). Sub zero air dryers take clean, dry air to new levels of cost-efficiency across a broad spectrum of operating conditions.
Many applications require very dry, high-quality air with sub zero dew points. CompAir’s desiccant dryers are the best option for the most stringent requirements – ISO Class 1-2 with a pressure dew point (PDP) as low as -70°C (-94°F). However, ISO Class 3 air, with a PDP of -20°C (-4°F), is sufficient for a large portion of the market. For applications that only require Class 3 air, we've expanded our family of high-quality air dryers with our CMT dryers. They combine the ease of maintenance and operation of a refrigerated dryer with the sub zero pressure dew points typically associated with a desiccant dryer.
