Adsorption Dryers

Adsorption drying is used where compressed air must be significantly drier than the level normally provided by a refrigerated dryer, including applications exposed to freezing conditions or sensitive processes.

The OM-A-DRY product information lists a standard -40°C pressure dew point, with -25°C and -70°C options depending on the model and specification.

Heatless adsorption dryers use a portion of already dried compressed air to regenerate the desiccant. This air consumption must be allowed for when sizing the compressor and dryer.

Selection should consider delivered airflow, working pressure, required dew point, purge-air demand, inlet temperature, ambient conditions and the required filtration arrangement.

Adsorption dryers require suitable filtration to protect the desiccant from oil, water and contamination. The exact arrangement should follow the dryer specification and required air-quality class.

Confirm airflow, pressure, dew-point requirement, electrical supply, filtration, condensate management, purge-air allowance, connection size and service clearance.
