Compressed Air Dryers

What do compressed air dryers do?

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. The type of contamination varies depending on the environments and altitude.

Water vapour is another natural ingredient which can be found in variable amounts in the air. The amount of water vapour or any other contaminating products which the air contains plays a very important role in the quality of the end-product produced by your compressor system.

Aside from the end-product, water is well known to have damaging and corrosive effects on your compressor system. Untreated air at atmospheric pressure contains large amounts of water as well as 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 filters are responsible for removing the oil and dirt content from the compressed air whilst air dryers are used to remove water vapour before the air reaches the point of use.

Why use a compressed air dryer?

Safe operation / protect your investment

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. An air dryer will help to keep your system running damage-free and your operation safe and reliable with long term results.

High-quality end-product / peace of mind

Whatever your application, you need to be sure that your end-product is of a high quality. Air that contains water vapour can cause product spoilage which can be very costly to businesses. An air dryer ensures that air is pure and dry before it reaches the point of use.

Different drying technologies

Refrigerant dryers

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.
