The action of your oil free refrigerated compressed air dryer and the way it protects your compressed air from excess moisture will vary depending upon the type of oil free refrigerated compressed air dryers you use. The standard types of dryers we use with compressed air systems include:

Refrigerated Dryers – The most common type of oil free refrigerated compressed air dryer you will see in an industrial compressed air system is the refrigerated dryer. These work on a simple mechanism of using one or more heat exchangers to cool down the hot compressed air, condense out the bulk of the water and remove the water through a separator equipped with an automatic drain. If you are looking for a reasonably-priced dryer and are not operating under extreme conditions where you need unusually high drying capability, these are often the best choice and most economical choice.

Desiccant Dryers – If you are in an extreme situation where your air is subject to very low temperatures or your products or environment cannot tolerate any moisture at all, you may be better served by a desiccant dryer. These dryers use a material such as activated alumina to adsorb water from the compressed air. Desiccant dryers come in a wide variety of types such as as heated, heatless or blower purge models.

Specialty Gas and Liquid Dryers – If your company works with exotic or dangerous gases or liquids that need drying, such as benzene, butane, hydrogen or landfill gas, there are specialty dryers designed to safely remove moisture from these products.

Membrane Dryers – Membrane dryers are very efficient dryers that dehumidify and depress the dew point as the air comes into the system. They are becoming increasingly popular as they require no electricity, are easy to maintain and are quiet.

Deliquescent Dryers – Deliquescent dryers are another brand of electricity-free, economical oil free refrigerated compressed air dryers that work with a pressure vessel containing a dissolving tablet that absorbs water vapor.
