There is always some moisture in the atmospheric air sucked in by the compressor. The amount of this humidity varies depending on the temperature of the air and geographical conditions. When the temperature of the compressed air coming out of the compressor in the working environment is reduced with an air dryer, the moisture, that is, the gaseous water, condenses and becomes liquid water. Humidity in the air causes corrosion of the installation, diameter losses and a series of the problems that trigger each other in compressed air systems. These damages, which cause loss of work, time and money, are prevented by evacuating the liquid formed, by cooling the compressed air with a refrigerated dryer (+3 °C Dew Point temperature). Clean and dry compressed air will reduce the operating cost of your facility and ensure it is an efficient operation.

Refrigerant Dryers, Blower Purge Dryers, Adsorption Dryers, Filtration and Condensate Treatment

The treatment of compressed air is often the most neglected aspect of any compressed air installation. We offer filtration, drying, storage and condensate management solutions to achieve the most stringent ISO 8573 classifications of Class 1.1.1.

Air receivers, filters, compressed air dryers and refrigeration dryers form part of our extensive air treatment product range.

Condensate management, treatment and correct disposal in terms of legislation is achievable with our range of oily water separators.

This is mandatory for all factories and a requirement for ISO14000 accreditation.


What is the difference between a refrigerated dryer and a desiccant dryer?

The most significant factor that can be used to draw a line between refrigerated and desiccant dryers, is the desired dew point. A

refrigerated air dryer is capable of providing a dew point between 3 – 5 degrees Celsius. This temperature is sufficient for most industrial

applications. On the other hand, if your application require high-quality compressed air, then you should opt for a desiccant air dryer.

Desiccant dryers can achieve a dew point of up to -70 degrees Celsius, which is a standard temperature that guarantees the cleanest and

driest compressed air.


COMPAC Refrigerant Dryers

As the design of a line filter with the feature of assembly and disassembly. It uses ambient temperature for pre-refrigeration of hot air inlet.

Blower Purge Desiccant Dryers

This kind of dryers has been designed to produce compressed dry air on more than -40°C and -70°C dewpoints and at the rate of dried compressed air by 2% dry air loss handling system.

Adsorption Desiccant Air Dryers

CNK cleverly organizes the flow of compressed air in towers before dewpoint reaches to higher rates than settled dewpoint. Therefore the outlet dewpoint of compressed air gets down to lower rate.


Pre and Post Coalescing filters which are designed not only to filter oil vapor and water, but also solid particles to an acceptable level as small as 0.01 micron in size.

Condensate Treatment

During the process of compressing air, atmospheric air along with water vapour and atmospheric contaminants (hydrocarbon, dust particles or chemical vapours) are drawn into the compressor intake.

Additionally, the compression chambers of most compressors require oil for lubrication, sealing and cooling. Once compressed, air flows into and after cooler to remove the heat of compression. As the air cools in the after cooler, water and hydrocarbon vapours will condense.

Additional condensation takes place as the air is further cooled in the piping and air dryer.

Environmental regulations strictly prohibit the discharge of oily wastes and chemicals, including the condensate drained from a compressed air system. Because of these requirements, municipalities regulate the discharge of compressor condensate to surface water, wastewater treatment facilities and sanitary sewers.
