Compressed air needs some form of treatment to achieve the desired air quality.

Drying compressed air prevents liquid water forming downstream where it can contaminate or damage the system causing operating problems, costly maintenance and repair expenses, as well as potential damage to the end product.

The most effective way to prevent condensation occurring in a compressed airline is to ensure that the air has a pressure dewpoint below the temperature to which any part of the system will be exposed.  Only compressed air that is totally clean and dry will ensure maximum savings.

A refrigeration air dryer extracts water vapour by the application of cooling and subsequent condensation. Condensation of water vapor occurs on internal cooling surfaces and is then separated and drained.  Refrigeration dryers are designed to deliver pressure dewpoints above 0 degrees C to prevent freezing on the internal cooling surfaces.  Air is reheated before it re-enters the system to prevent pipe from ‘sweating’ in humid conditions. The refrigeration air dryer cools the incoming air, condensing the water vapors into a liquid that is then drained from the system.   This method of drying is very popular as it produces dew points which are adequate for most applications in an energy efficient and reliable manner. Typically, there is only a 5% additional energy cost for drying compressed air with a refrigeration dryer.

There are a number of things to be considered , e.g. maximum flow capacity when determining the correct sized dryer for your application, so please contact us to discuss your requirements.

We offer both the Chicago Pneumatic and MTA range of refrigeration dryers.  Other types of air dryers such as desiccant dryers are also available upon application.
