How a Heatless Adsorption Dryer Works

The dryer uses two desiccant-filled columns operating alternately. One column dries the compressed air under pressure while the second regenerates using a portion of already dried compressed air at approximately atmospheric pressure.

The columns then switch duty so the drying process can continue while the saturated desiccant is regenerated.

How to Size an Adsorption Dryer

When Should I Choose an Adsorption Dryer?

Adsorption drying is appropriate where moisture remaining after conventional refrigeration drying would still create a problem.

• Moisture-sensitive manufacturing or process equipment
• Instrumentation and control-air applications
• Critical production processes requiring very low dew points
• Pipework or equipment exposed to temperatures where residual moisture could freeze
• Applications where a refrigerated dryer cannot achieve the required pressure dew point

Protect the Desiccant with Correct Filtration

Adsorption media should be protected from liquid water, oil aerosol and particulate contamination. The precise filtration arrangement should follow the dryer specification and the air-quality requirement of the process.

Before Installing an Adsorption Dryer

• Confirm required downstream airflow
• Allow for regeneration purge-air consumption
• Confirm normal and maximum working pressure
• Establish the required pressure dew point
• Check inlet and ambient temperature limits
• Provide the required pre- and after-filtration
• Confirm electrical supply and connections
• Provide condensate management where required upstream
• Allow access for filter and desiccant servicing
