Air Treatment



When air is compressed it makes a lot of heat and water. Also, any other contaminants in the air stream such as dirt and oil are passed downstream of the compressor. The water and the dirt can cause early equipment failure, quality problems and lost production time.

Airdyne offers multiple solutions to clean up compressed air prior to entering the plant air system – and prevent problems:

Filtration

The first step in removing contaminants from the air system is a filter. A coalescing filter will remove solid particulates down to 0.001 microns at 99.99% efficiency. A coalescing filter is installed prior to any dryer and extends the life of the dryer's heat exchangers or desiccant. A particulate filter is designed to remove particles 0.1 microns and larger at 99.99% efficiency. A particulate filter is installed after a dryer to catch any contaminants before they enter production machinery.

Refrigerated Air Dryers

Refrigerated air dryers provide a 35-39°F dewpoint – that’s suitable for most indoor processes. These dryers are available from 15 to 5,000 SCFM, and in premium efficient cycling, or standard efficiency non-cycling configurations.

Desiccant Air Dryers

Desiccant air dryers can provide a dewpoint as low as -100°F. They are available as a heatless, externally heated or heat of compression design. These dryers are typically used in process applications where there is a zero tolerance for moisture. Desiccant dryers are also used in outdoor installations where freezing temperatures would cause a malfunction of a refrigerated dryer.

Membrane Air Dryers

Membrane dryers originated in the nitrogen generation industry where they have been successfully used for decades. A tube is filled with hollow membranes that allow compressed air to pass but remove water vapor. These dryers give a -80°F dewpoint relative to the incoming air temperature. Membrane dryers have no moving parts and require no maintenance, and therefore have a very long life.
