Our range of compressed air dryers protects your systems and processes in a reliable, energy-efficient and cost-effective way.

Protecting your compressed air systems and processes

Treated air helps prevent pipework corrosion, product spoilage and premature failure of pneumatic equipment

Maintaining the quality of your end product

A complete range of products with dew points from +3 to -70 °C to ensure the correct air quality for your application

Energy-efficient air dryers

All our compressed air dryers are designed to perform in the most energy-efficient and environmentally friendly way, and thus contributing to a reduced carbon footprint

Water in your compressed air system?

Why is their water in my compressor?

This happens almost everywhere, but it can have serious consequences for your compressed air system and the quality of the end product. Causes of water in your compressed air system When the air is compressed, condensation occurs. 
The following factors determine the amount of water: 

  • Inlet conditions 
  • Ambient air quality 
  • Pressure 

The moisture content is higher in warm and humid air, which means that more water comes out of the compressor. The compressed air contains less water when the pressure is higher and the easier it can be dried. Think of a sponge that is soaked with water; the more it is squeezed, the less water it contains.

Why add an air dryer to your compressed air system?

Many tools and equipment, driven by compressed air, cannot withstand water or moisture.Many processes, using compressed air, are processing products that cannot withstand water or moisture. Inherent to the compression cycle, free water is often formed in the compressed air circuit.

Untreated compressed air, which contains solid, liquid, and gaseous contaminants, poses a significant risk as it can damage your air system and your end product. Moisture, one of the main components of untreated air, can cause the following problems: 

  • Water in a compressed air system often causes corrosion which leads to rust forming in the compressed air system. Those rust particles will be released and transported through the compressed air system. Corrosion of air or gas-operated instruments giving incorrect measured values, causing interrupts or switches off system processes. 
  • Cause of wear and tear of the inner part of the compressed air line, leading to holes and thus to air leaks, resulting in a pressure drop. Meaning a loss of energy and money. 
  • This can result in damage or failure of the compressed air tools and can cause contamination of the processed products. Free water or moisture in a compressed air system can sustain bacteria growth or the moisture can be absorbed by the processed product leading to quality deviations and product spoilage. For example: may adversely affect the color, adhesion, and surface finish of paint applied with compressed air. This could lead to rejection of your product and affect your profitability. 
  • Water can freeze in control lines in cold weather, leading to the malfunction of the controls.

How does an air dryer work?

Air dryers remove moisture from the air.
Each dryer system- desiccant dryerrefrigerated dryer, and membrane dryeruses its own technique.

The measurement of dry compressed air after processing is known as its 'dew point'. The lower the temperature of the dew point, the less amount of water vapor in the air. Dew point means the actual temperature where condensation begins. For example, if the dew point is -40 C° this means condensation starts only if compressed air temperature goes down to -40 C°.

All about compressed air dryers

How to choose the correct air dryer for my aircompressor?

Choosing the right air dryer for your compressor. It is important to determine the moisture requirements for your equipment before selecting the air dryer.


What is a variable speed drive air dryer?

Variable speed drive (VSD) dryer cuts energy cost for your compressed air system while producing air at a constant low dew point. It controls the speed of the compressor to match your air demand.
